Single stack gives you under 0.65 Angstrom at 656.28 nm, and adding a double stack module brings that under 0.45 Angstrom. Barometric pressure tuning shifts the passband instantly, so filaments, plage and prominences can each be brought to peak contrast without touching the tilt of any optic.\u003c\/p\u003e\n    \u003cp\u003eWith 910 mm of focal length at f\/7, the LS130MT reaches a theoretical maximum magnification of 225x and produces a solar disk large enough to fill a modern sensor.

Viewing\u003c\/h2\u003e\n        \u003cp\u003eThe Lunt LS40THa is the smallest aperture telescope in the Lunt dedicated solar line, built around a 40 mm custom doublet optimized for the 656 nm hydrogen alpha wavelength. At 400 mm focal length and f\/10, it delivers a solar disk of roughly 4.0 mm at prime focus, which suits both relaxed visual sessions and imaging with a small sensor.\u003c\/p\u003e\n    \u003cp\u003eTuning is handled by tilting the internal dedicated etalon, which shifts the passband instantly so you can move between prominences on the limb and structure on the face of the disk. Single stack bandpass sits below 0.45 Angstrom, and adding a double stack module narrows that to below 0.29 Angstrom for higher contrast on filaments and active regions.\u003c\/p\u003e\n    \u003cp\u003eChoose a 5 mm, 6 mm or 12 mm blocking filter and either the 1.25 inch mini helical focuser or a Feather Touch upgrade, depending on the eyepieces and cameras you plan to use.

50mm\u003c\/h2\u003e\n        \u003cp\u003eThe Lunt 50mm Solar Ready Kit is built on the LS50THa, a 350mm f\/7 dedicated hydrogen-alpha telescope with an internal pressure tuned etalon. Lunt rates the bandpass at 0.6 angstroms and the Doppler True barometric tuner lets you shift the passband across the whole aperture, so you can scan the chromosphere at different depths.\u003c\/p\u003e\n    \u003cp\u003eAn integrated clamshell base carries the SunLock red dot sun finder and the Vixen dovetail, so the tube drops onto a photo tripod or a small equatorial mount without extra hardware. The Standard trim uses a helical focuser and a single 12mm eyepiece. The Enhanced trim adds a rack and pinion focuser and three eyepieces.\u003c\/p\u003e\n    \u003cp\u003ePremium Plus includes the LS50C compact double stack filter, which threads onto the front of the tube without tools and drops combined system bandpass to roughly 0.35 angstroms.

The black anodized body is built heavy duty, so it holds the scope securely while you slide it fore and aft to balance the load on your mount.\u003c\/p\u003e\n    \u003cp\u003eA slot on the top of the ring accepts the Tele Vue Sol-Searcher Sun Finder, so you can add a sighting aid without drilling the tube. The base is tapped 1\/4-20, which lets you attach the ring to a dovetail bar, a photo head or any fitting that uses the same thread.\u003c\/p\u003e\n    \u003cp\u003eMost LS60THa and LS80THa packages already include this clamshell, so treat it as a spare, a second ring for a two point mounting setup or a replacement. It changes only how the telescope is held.

Imaging\u003c\/h2\u003e\n        \u003cp\u003eThis 0.8x reducer and flattener from Lunt does two jobs in one barrel. It shortens the effective focal length of your telescope by a factor of 0.8, which widens the field and speeds up the system for imaging, and it flattens the focal plane so stars and solar detail stay sharp out toward the corners of a large sensor.\u003c\/p\u003e\n    \u003cp\u003eThe optics are multi coated and the housing is aluminum, so the unit stays light on the back of a focuser that may already be carrying a camera and filter wheel.

Reducers only deliver their rated factor and flat field at the correct distance from the sensor, so budget for spacer rings when you build the imaging train.

Upgrades\u003c\/h2\u003e\n        \u003cp\u003eThe Lunt MT series gives you a night sky refractor first and a solar platform second. Each optical tube assembly is an f\/7 apochromatic refractor built on precision aligned ED glass, and each one ships ready to accept a Lunt hydrogen alpha module later. You choose the aperture, then decide when to add the solar side.\u003c\/p\u003e\n    \u003cp\u003eFour apertures cover the range. The 70mm works at 420mm focal length, the 80mm at 560mm, the 100mm at 714mm and the 130mm at 910mm, so every tube holds the same f\/7 focal ratio. Smaller tubes stay travel friendly at around five and a half pounds, while the 130mm delivers the most resolution for deep sky imaging.\u003c\/p\u003e\n    \u003cp\u003eA dual speed 10:1 rack and pinion focuser handles fine adjustment, and a ring or clamshell assembly with a Vixen style dovetail lets you mount on standard saddles. When you want the Sun, swap the focuser for a Lunt hydrogen alpha module and blocking filter and the same tube reaches 0.7 Angstrom bandwidth or tighter. A fitted hard case protects the tube in transit.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kt-hero-img\"\u003e\n    \u003cdiv class=\"kt-sq\"\u003e\n      \u003cimg

Light\u003c\/h2\u003e\n        \u003cp\u003eThis calcium K blocking module from Lunt works at 393.4 nm, the calcium K line at the violet edge of the visible spectrum. It shows a lower, cooler layer than hydrogen alpha, where supergranulation cells and bright plage trace the magnetic network. Running CaK alongside H-alpha tells you more about the structure and depth of active regions.\u003c\/p\u003e\n    \u003cp\u003eTreat CaK as a photographic wavelength. Most adult eyes respond poorly at 393 nm because the cornea and lens yellow with age, so many observers see the violet colour but little contrast. Observers who have had cataract surgery often see far more. A camera records the detail readily, which is why the module is built around imaging.\u003c\/p\u003e\n    \u003cp\u003eThe module carries internal narrowband filters for a bandpass under 2.4 Angstrom and mounts on most standard night time refractors, or on a Lunt modular telescope in its night configuration. Pick the blocking aperture by focal length: B600 to 600 mm, B1200 to 1200 mm and B1800 to 1800 mm, each rated for apertures up to 100 mm.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv

Refractor\u003c\/h2\u003e\n        \u003cp\u003eThe Lunt LS152THa is a dedicated hydrogen alpha instrument built around a 152 mm unobstructed refractor and a single interference HD etalon. Nothing sits in the light path to soften contrast, so the system performs at both low and high magnification. High contrast coatings run through the optical train to keep scatter down across the full solar disk.\u003c\/p\u003e\n    \u003cp\u003eDoppler True pressure tuning is the reason this telescope behaves differently from tilt tuned designs. The internal etalon holds a bandpass below 0.45 Angstrom at 656 nm, and the pressure tuner shifts it toward and away from you. Follow a filament from base to tip and watch its structure move through the line, adding depth to what you see.\u003c\/p\u003e\n    \u003cp\u003eAt 900 mm and f\/6 the LS152THa suits visual observers and imagers alike. Choose a B1200 diagonal for visual work, a B1800 diagonal for a wider field, or a B3400 straight through unit for large sensors, and step up to a 2.5 inch Feather Touch focuser in the top configuration.

nothing else to source before first light. A 350 mm focal length at f\/7 keeps the tube short enough to travel with while still resolving prominences on the limb and the larger active regions on the disk.\u003c\/p\u003e\n    \u003cp\u003eTuning uses the Lunt Pressure Tuner, a barometric system that shifts the passband by changing air pressure inside the etalon housing rather than by tilting glass. That keeps the image evenly tuned from one edge of the disk to the other, and the adjustment is fine enough to bring up filaments and surface texture that a coarse tilt would move straight past.\u003c\/p\u003e\n    \u003cp\u003eSingle stack bandpass sits below 0.6 Angstrom, and a double stack module takes it below 0.4 Angstrom when you want the highest surface contrast.

Remove the solar module and the same tube works as a night time refractor.\u003c\/p\u003e\n    \u003cp\u003eAll three trims share a 2 inch dual speed rack and pinion focuser with 10:1 fine focus, ZWO EAF compatibility and 55 to 60mm of travel, so motorised focusing and camera trains are supported from the start. The Standard trim pairs a B600 blocking filter with a 16mm flat field eyepiece and a 4 inch dovetail.\u003c\/p\u003e\n    \u003cp\u003eEnhanced moves up to a B1200 blocking filter with 12mm of clear aperture and swaps the fixed eyepiece for a 7.2 to 21.5mm zoom. Premium Plus keeps the B1200 and adds the LS50FHa front mounted double stack filter for a combined bandpass under 0.28 angstroms, along with a 6 inch dovetail for balance.\u003c\/p\u003e\n

Correctors\u003c\/h2\u003e\n        \u003cp\u003eThe Tecnosky Horizon binoviewer lets you observe with both eyes through a single telescope. Its head combines prism and mirror elements and carries built in optical correctors, so on a Lunt hydrogen alpha telescope it reaches focus without an optical corrector system lens or a stack of spacers, which is often the obstacle with older binoviewer designs.\u003c\/p\u003e\n    \u003cp\u003eMagnification through the head is 1:1, so your eyepieces keep their marked focal lengths. Eyepiece holders are 1.25 inch and Lunt publishes an eye relief range of 58 mm to 74 mm along with a rotatable diopter adjustment for balancing focus between your eyes. Unobstructed clear diameter is 17.3 mm and the head weighs 24.9 ounces.\u003c\/p\u003e\n    \u003cp\u003eOverall dimensions are 127 by 106.7 by 50.4 mm. The head is compatible with Lunt solar telescopes and with Newtonian and refractor telescopes generally, and Lunt suggests pairing it with its flat field eyepieces in 8, 12, 16, 19 and 27 mm for solar work behind proper solar filtration.

Telescope\u003c\/h2\u003e\n        \u003cp\u003eA double stack etalon puts a second filter in series with the etalon already in your Lunt MT telescope. Single stack gives you 0.7 Angstrom or better. Adding the second etalon takes the system to 0.5 Angstrom or better, and Lunt reports tighter figures near 0.28 Angstrom on current internal modules. Contrast on the disk climbs sharply.\u003c\/p\u003e\n    \u003cp\u003eChoose the version that matches your telescope. The LS50FHaP and LS60FHa front mount on the LS60MT and LS60THa. The internal SFPT module drops inside the LS80MT and LS100MT. The LS130MTP module serves the LS130MT. The LS100FHa front mount covers the LS100MT and LS100THa. Each one leaves the night sky configuration untouched.\u003c\/p\u003e\n    \u003cp\u003eAt the narrower bandwidth you see filaments resolve into dark cores and multiple strands, plage boundaries sharpen into cellular networks, and active regions show more magnetic structure. The trade is brightness, so plan on lower magnification or longer exposures. Pressure tuning shifts the passband on and off band without tilting the etalon, and the internal modules install without a factory return.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv

Every etalon is individually tested on Lunt metrology equipment and rated at 0.4 Angstrom, so the bandpass on your unit is verified rather than estimated. Prominences, filaments and active region structure all show clearly.\u003c\/p\u003e\n    \u003cp\u003eUnlike the center obstructed sets, the full 50mm aperture stays clear, which helps resolution and evenness of illumination across the disc. Tilt tuning shifts the passband across the hydrogen alpha line at 656.28 nm, and the filter lifts off in seconds so the same refractor returns to night sky work after sunset.\u003c\/p\u003e\n    \u003cp\u003eThe filter set is specified with a blocking filter matched to your focuser and focal length, in either a 2 inch or a 1.25 inch fitting. A B600 suits focal lengths to 540 mm, a B1200 to 1080 mm visually, a B1800 to 1620 mm, and a B3400 covers the longest focal lengths and large sensor full disc imaging.\u003c\/p\u003e\n

Stars\u003c\/h2\u003e\n        \u003cp\u003eThe Lunt LS60MT is a universal day and night telescope built on a professional grade FLP51 ED doublet. In its shipped hydrogen alpha configuration the working aperture is 60 mm behind the etalon module, while the native objective measures 70 mm for night use. Focal length is 420 mm at f\/7, giving a short tube that carries easily and settles quickly on a small mount.\u003c\/p\u003e\n    \u003cp\u003eBecause the hydrogen alpha module is modular rather than built into the tube, you can lift it off together with the pressure tuner and fit a standard focuser in its place. That turns the same optical tube into a conventional ED refractor for lunar, planetary, deep sky and terrestrial viewing, so a single case covers your daytime and night time sessions.\u003c\/p\u003e\n    \u003cp\u003eSolar tuning uses Doppler True barometric pressure tuning, which gives instant doppler shifting and fine control over what the passband reveals. Single stack bandpass is below 0.45 Angstrom and double stacking brings it below 0.40 Angstrom. Blocking filters are offered at 6 mm, 12 mm and 18 mm in diagonal and straight through form, all with a 6 Angstrom bandpass.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv

Solar Imaging\u003c\/h2\u003e\n        \u003cp\u003eThis PC-USB pressure tuner from Lunt replaces the manual pressure tuning knob with a microprocessor controlled unit you can drive from a computer over USB. A one eighth inch airline runs from the controller to the telescope and can be made any length you need, so the box can sit indoors while the telescope stays out under the sky.\u003c\/p\u003e\n    \u003cp\u003eFront panel control is deliberately simple: one button raises pressure, one lowers it, and a digital readout plus indicator lights show where you are. The unit holds the pressure setpoint to 0.3 PSI and auto compensates for internal pressure drift caused by temperature swings, so your chosen wavelength position stays put through a long session.\u003c\/p\u003e\n    \u003cp\u003eIt runs more than twelve hours on internal batteries and accepts 12 to 15 VDC external power that runs the unit and charges at the same time. Any existing Lunt pressure tuned product can be retrofitted without returning it to the factory. Closed loop feedback of etalon pressure also lets you correlate pressure changes with doppler shifted events.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kt-hero-img\"\u003e\n

The Standard trim uses a B1200 filter and a 19mm eyepiece.\u003c\/p\u003e\n    \u003cp\u003eEnhanced upgrades to the B1800 blocking filter with 18mm of clear aperture for full frame sensor coverage, and adds 8mm, 12mm, 16mm and 19mm flat field eyepieces.

Scopes\u003c\/h2\u003e\n        \u003cp\u003eLunt offers a focuser to match nearly every one of its solar telescopes, from a compact helical unit for small refractors up to a two inch dual speed rack and pinion. Choosing the right one comes down to the thread interface on your blocking filter or rear cell, the weight of the gear you plan to hang off it, and how fine you need the final adjustment to be.\u003c\/p\u003e\n    \u003cp\u003eThe 1.25 inch mini helical focuser threads T2 male to T2 female and gives ten millimeters of non rotating travel with a brass compression ring and a locking collar. The 1.25 inch rack and pinion steps up to a rotatable draw tube, half an inch of travel, positioning accuracy of plus or minus 0.002 inch, and a load rating of six to eight pounds.\u003c\/p\u003e\n    \u003cp\u003eFor imaging, the 10:1 versions matter. The 1.25 inch rack and pinion with 10:1 fine focus suits the LS40THa and LS50THa, while the two inch rack and pinion carries roughly 55 to 60 mm of travel, a 10:1 reduction, and works with ZWO EAF and Optec FocusLynx motor kits. At the top of the range, the SLF1.5 and SLF2.5 two inch draw tube focusers are Starlight Instruments Feather Touch units built in a Lunt specific configuration.

Viewing\u003c\/h2\u003e\n        \u003cp\u003eThis polarizing filter unit from Lunt pairs with a Lunt White Light Solar Wedge to give you control over image brightness. The wedge and its ND3 filter already bring sunlight down to a safe level, and the polarizer then lets you trim the remaining glare so the disk sits at a comfortable level for your eyes.\u003c\/p\u003e\n    \u003cp\u003eInstallation is simple. Screw the filter onto the barrel of your eyepiece, drop the eyepiece into the wedge, then rotate the eyepiece or the top filter element to vary transmission. Choose the size that matches your wedge barrel, PF1.25 for the 1.25 inch wedge and PF-2 for the 2 inch wedge.\u003c\/p\u003e\n    \u003cp\u003eThis filter is a brightness control, not a solar filter. It must never be used on its own to look at the Sun. Always observe through properly filtered equipment such as a Herschel wedge on a refractor or a dedicated hydrogen alpha telescope, and add the polarizer only inside that safe optical

Telescopes\u003c\/h2\u003e\n        \u003cp\u003eA dedicated Lunt hydrogen alpha telescope already reaches 0.7 Angstrom or better in single stack. Adding a double stack filter places a second etalon in series and pulls the combined bandwidth to 0.5 Angstrom or better. Lunt publishes tighter figures still on the current 40mm and 152mm systems. The Sun's surface gains contrast immediately.\u003c\/p\u003e\n    \u003cp\u003eThree versions cover the dedicated range. The LS40FHaP is a 40mm front mounted tilt tuned etalon for the LS40THa, and Lunt lists the pair at under 0.29 Angstrom combined. The LS50CP is a compact 50mm filter that threads onto the front of an LS50THa in seconds. The DSII\/LS152T is an internal module for the LS152THa.\u003c\/p\u003e\n    \u003cp\u003eExpect filaments to break into dark cores and multiple strands, prominences to show internal threading from base to tip, and plage to separate cleanly from the background chromosphere. A Lunt blocking filter is required at all times, since the double stack filter is not a standalone safety device. Installation needs no tools and no factory return.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kt-hero-img\"\u003e\n    \u003cdiv class=\"kt-sq\"\u003e\n      \u003cimg

Lunt states the airline can be installed at any length.\u003c\/p\u003e\n    \u003cp\u003eTwo lengths are offered. PC-USBHOSE25 adds twenty five feet, which is usually enough to reach from a scope on the lawn to a nearby doorway or shed. PC-USBHOSE100 adds one hundred feet for a permanent pier, an observatory run, or a fully remote setup where the operator is well away from the instrument.\u003c\/p\u003e\n    \u003cp\u003eThe hose is an accessory for the PC-USB controller and does not tune anything on its own.

broadband AR. At 560 mm focal length and f\/7 it carries a theoretical maximum magnification near 140x, which leaves you working room on solar active regions in the morning and on planets or globular clusters the same evening.\u003c\/p\u003e\n    \u003cp\u003eFitted with the hydrogen alpha module and Doppler True pressure tuner, the tube observes the Sun with barometric fine tuning instead of tilt, so the passband stays even across the whole disk. Single stack bandpass is below 0.65 Angstrom, and adding a double stack module narrows it below 0.45 Angstrom for stronger contrast on filaments and surface structure.\u003c\/p\u003e\n    \u003cp\u003eLifting the hydrogen alpha module off and fitting a focuser in its place converts the same optical tube into a conventional apochromatic style refractor for lunar, planetary, deep sky and terrestrial work. CNC mounting rings and a Vixen style dovetail handle attachment, a red dot sun finder handle speeds up acquisition, and an aluminum finished hard case protects the tube in transit.\u003c\/p\u003e\n

Alpha\u003c\/h2\u003e\n        \u003cp\u003eThis 60mm full aperture H-alpha etalon package from Lunt places a 60mm tilt tuned etalon in front of your refractor with no central obstruction. Each etalon is individually tested on Lunt metrology equipment and carries a verified 0.4 Angstrom bandpass, so the figure on your unit is measured rather than assumed.\u003c\/p\u003e\n    \u003cp\u003eThe extra aperture over the 50mm set raises resolution and image brightness, which helps when you push magnification on filament structure or want a cleaner full disc frame. Tilt tuning shifts the passband across the hydrogen alpha line at 656.28 nm, and the filter lifts straight off so the refractor returns to night sky duty.\u003c\/p\u003e\n    \u003cp\u003eA Lunt blocking filter must sit in the optical path at all times. Order the set with a B600 for focal lengths to 540 mm, a B1200 to 1080 mm, a B1800 to 1620 mm or a B3400 for the longest focal lengths, and pick the 2 inch or 1.25 inch fitting to match your

Carry\u003c\/h2\u003e\n        \u003cp\u003eThe Lunt 100mm Solar Ready Kit brings observatory class aperture to a tube you can still carry. Lunt lists the Standard trim as a 102mm f\/6.5 doublet at 663mm focal length, while the Enhanced and Premium Plus trims are listed as the LS100MT with an FPL53 ED triplet at f\/7. All three use an internal pressure tuned etalon.\u003c\/p\u003e\n    \u003cp\u003eThe etalon is rated at a verified 0.45 angstrom bandpass with Doppler True barometric tuning, so you can shift the passband across the whole aperture while observing. Shared hardware across the range includes mounting rings with a solar handle and red dot sun finder, an 8 inch Vixen dovetail, a 2 inch 10:1 focuser and a hard case.\u003c\/p\u003e\n    \u003cp\u003eStandard pairs a B1200 blocking filter with a single 19mm flat field eyepiece. Enhanced moves to the B1800 with 18mm of clear aperture and adds 8mm, 12mm, 16mm and 19mm eyepieces. Premium Plus keeps the B1800 and includes the SFPT internal double stack module for a combined system bandpass below 0.28 angstroms, plus a zoom eyepiece.\u003c\/p\u003e\n  \u003c\/div\u003e\n

Confidence\u003c\/h2\u003e\n        \u003cp\u003eLunt builds two small machined adapters that solve the most common fit problems on a solar telescope back end. One steps a 2 inch blocking filter or focuser down to 1.25 inch, the other threads onto a T2 blocking filter so you can drop in 2 inch eyepieces. Both are metal bodied and both use a non marring brass compression ring.\u003c\/p\u003e\n    \u003cp\u003eADP2-1.25 is the part to reach for when you own a 2 inch Lunt blocking filter but want to observe with 1.25 inch eyepieces, and it works equally well as a general reducer inside any 2 inch diagonal or focuser. The brass ring grips the barrel evenly instead of digging a thumbscrew dimple into it.\u003c\/p\u003e\n    \u003cp\u003eLST2-2 inch goes the other way. Remove the 1.25 inch eyepiece tube from your blocking filter, thread this adapter onto the exposed T2 thread, and you can use 2 inch eyepieces. Lunt lists it for its blocking filters, hydrogen alpha and calcium K telescopes except the LS35THa, and Ca-K modules.

Systems\u003c\/h2\u003e\n        \u003cp\u003eThe High Resolution Glass upgrade is an optional element for a Lunt internal double stack system. It targets the faint background glow that internal double stack modules produce, and it does that without changing how the double stack tunes or how narrow the passband becomes. You keep the 0.5 Angstrom or better bandwidth and gain a cleaner background.\u003c\/p\u003e\n    \u003cp\u003eThree versions match three double stack systems. The HRG\/80 fits the double stack filter on an 80THa. The HRG\/100 fits the double stack filter on a 100THa. The HRG\/SFPT fits the internal SFPT module used on the 80MT and 100MT universal telescopes. Choose the one that matches the module already on your telescope.\u003c\/p\u003e\n    \u003cp\u003eImagers benefit most. With less scattered light in the field, prominences at the limb separate from the sky background and edge detail holds together at higher stretch. Visual observers see a darker field around the disk as well. Each unit ships at about one pound, so it adds no meaningful load to your mount or your balance.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kt-hero-img\"\u003e\n    \u003cdiv

The backing plate is the rear interface of the optical tube and the focuser mounts to it, so the two are supplied together as one part.\u003c\/p\u003e\n    \u003cp\u003eIts purpose is conversion. Remove the rear pressure tuned etalon section from the LS152THa and fit this plate and focuser in its place, and the same optical tube becomes a night time refractor.

tuned etalon. Lunt publishes a verified 0.45 angstrom bandpass measured on metrology equipment rather than estimated, and the full 40mm aperture stays unobstructed so contrast holds right across the solar disk.\u003c\/p\u003e\n    \u003cp\u003eChoose the trim that matches how you observe. The Standard configuration pairs a B600 blocking filter with a mini helical focuser, a 4 inch dovetail and a 12mm eyepiece.

Every trim ships in a fitted hard case.\u003c\/p\u003e\n    \u003cp\u003eStep up to Premium Plus and you add the LS40FHa double stack filter, which places a second etalon in series and brings combined system bandpass below 0.29 angstroms. That trim also carries a 6 inch dovetail for balance with the filter fitted, plus a 7.2 to 21.5mm zoom eyepiece covering roughly 19x to 56x.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv

Use\u003c\/h2\u003e\n        \u003cp\u003eThese are 1.25 inch prism diagonals that Lunt supplies for daytime and terrestrial work rather than for solar observing. The 45 degree unit uses a full size Amici prism to give a fully corrected image, left to right and up and down, which is what you want for reading distant signs, watching birds, or scanning a landscape through a refractor.\u003c\/p\u003e\n    \u003cp\u003eThe 45 degree angle also sits at a comfortable head position for horizontal targets, where a 90 degree diagonal forces you to crane your neck. The GSOPD90 covers the other case: a conventional 90 degree prism for night time astronomy and for terrestrial targets high above the horizon, giving an up and down correct, left to right reversed view.\u003c\/p\u003e\n    \u003cp\u003eBoth use full size prisms so the field stays fully illuminated and free of vignetting. Neither of these diagonals is a solar filter and neither makes a telescope safe for the Sun. Point a telescope at the Sun only when the correct certified solar filtration is fitted at the front of the instrument or in a dedicated Lunt solar system.\u003c\/p\u003e\n  \u003c\/div\u003e\n

Each bar is machined from aluminum and finished in black anodizing, with four mounting holes tapped 1\/4-20 so you can position the tube where it balances best on your mount.\u003c\/p\u003e\n    \u003cp\u003eThree lengths are available. The 4 inch bar (LS100PS) measures 100 mm and suits compact tubes, the 6 inch bar (LS150PS) measures 150 mm for mid size scopes, and the 12 inch bar (LS300PS) measures 300 mm to give larger instruments a long sliding range for balance.\u003c\/p\u003e\n    \u003cp\u003eTwo connecting screws are supplied with every bar. Lunt solar telescopes all use Vixen style mounting, so the bar drops straight onto standard equatorial and alt azimuth saddles. Fit the bar before you set up for the Sun, and keep proper solar filtration installed on the telescope for every observing session.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv

A 100 mm professional grade APO triplet with FPL53 glass and ion assist broadband coatings handles the night sky, while a modular hydrogen alpha etalon drops into the same optical path for full disk solar viewing. Swap the module and focuser, and the instrument changes role in minutes.\u003c\/p\u003e\n    \u003cp\u003eOn the Sun, the internal etalon delivers a bandpass below 0.65 Angstrom in single stack form and below 0.45 Angstrom when double stacked. Doppler True barometric pressure tuning lets you shift across the hydrogen alpha line at 656.28 nm, so prominences, filaments, active regions and surface granulation each come into their best contrast as you tune.\u003c\/p\u003e\n    \u003cp\u003eAt 714 mm focal length and f\/7, the LS100MT reaches a theoretical maximum magnification of 175x and pairs well with a wide range of eyepieces and cameras.

Scope\u003c\/h2\u003e\n        \u003cp\u003eThis 40mm center obstructed H-alpha set from Lunt mounts over the centre of your existing refractor objective, converting a night sky instrument into a solar telescope in seconds. The 40mm etalon delivers a bandpass below 0.65 Angstrom at 656.28 nm, so prominences, filaments, active regions and chromospheric texture all come into view without a dedicated solar tube.\u003c\/p\u003e\n    \u003cp\u003eTuning is by tilt, so you angle the housing to centre the hydrogen alpha line and start observing. There are no pressure systems, no air pumps and no external controls to manage. A centre mounted foot supports the etalon, which means the filter carries a central obstruction; plan your aperture and contrast expectations around that design choice.\u003c\/p\u003e\n    \u003cp\u003eEach set ships with your choice of a B600 or B1200 blocking filter and one machined adapter plate sized to your telescope, included in the set. The plate is matched to the outside diameter of your dew shield, so to measure for your adapter plate take a measurement of the outside diameter of the dew shield on your refractor telescope. Nine plate steps run from 55 to 60 mm up to 95 to 100 mm, covering objective housings up to 4 inches. Removal takes seconds when the refractor is needed for night use.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kt-hero-img\"\u003e\n    \u003cdiv class=\"kt-sq\"\u003e\n      \u003cimg

Aperture\u003c\/h2\u003e\n        \u003cp\u003eA Lunt blocking filter is required with every Lunt hydrogen alpha etalon or telescope. It is not just a stop; the housing carries an additional filter stack that makes the package safe and gives the final image its contrast. Lunt only warrants safety and performance when one of its own blocking filters sits in the optical path.\u003c\/p\u003e\n    \u003cp\u003eClear aperture sets how much of the light cone gets through. B600 gives 6 mm, B1200 gives 12 mm, B1800 gives 18 mm and B3400 gives 34 mm. Larger apertures hold a fully illuminated field at longer focal lengths, which is what full disc imaging with a bigger sensor needs. Match the size to your telescope focal length.\u003c\/p\u003e\n    \u003cp\u003eHousings come in three styles. The s versions are 2 inch straight through tubes with T2 and 2 inch connections. The d1 versions are star diagonals with a 1.25 inch eyepiece holder and a T2 connection, and the d2 versions are star diagonals with a 2 inch eyepiece holder and T2.
