View full detailsA GoTo mount, a dew heater, a camera and a phone running a star chart will flatten a small battery well before the sky gets good. Running out of power at one in the morning is one of the more avoidable ways to lose a clear night.
This is the field power side of a setup: a rechargeable pack with a red LED that will not wreck your dark adaptation, a mains supply for PMC-Eight mounts when you are observing from home, and the USB pressure tuner controller for Lunt solar telescopes.
Working out what your mount actually draws? Tell us the model and we will size it with you.

Every light on this page is night-vision safe. One glance at a white screen costs twenty minutes of dark adaptation.
Mount power is fussy about voltage and tip size. We match it to your mount rather than guessing.
The 8300 mAh pack carries a GoTo mount, a camera and a phone through a long session.
Every item on this page ships free within the United States.
Four products across field power, mains supplies and controllers.

8300 mAh with 12V and 5V outputs and a built-in deep red LED flashlight.

Mains supply for PMC-Eight mounts when you are observing from home.

USB pressure tuner controller for tuning a Lunt etalon from a computer.

Extension hose for the Lunt pressure tuner, in 25 and 100 foot lengths.
The practical ones.
The 8300 mAh pack holds 99.6 Wh. A small GoTo mount typically draws well under 10 W tracking, so a full night is realistic with capacity to spare for a camera and a phone. Slewing repeatedly and running a dew heater will shorten that considerably.
Dark adaptation takes roughly twenty minutes to build and about a second of white light to destroy. Deep red light lets you read a chart or find a knob without resetting your eyes.
Voltage, current and the plug tip all have to match, and getting it wrong can damage the electronics. If you are not certain, send us your mount model before you plug anything into it.
No, and the name is misleading. It is the pneumatic air line that extends the reach of the Lunt pressure tuner, so you can tune the etalon from further away from the telescope.
Power keeps the session going. These pages cover the rest of it.
