An 80mm FCD100 Triplet Bundled with a Dedicated Field Flattener

This fast f/6 refractor pairs genuine HOYA FCD100 extra-low dispersion glass with an air-spaced triplet lens system and fully multi-coated optics for superior color correction and sharpness in a compact 80mm package.

Designed for both astrophotography and visual observation, the tube comes bundled with a dedicated field flattener optimized for f/5 to f/7 focal ratios, correcting field curvature and reducing coma for cleaner stars across the frame.

The 2.5-inch hexagonal focuser supports up to 10 lbs of imaging gear, and the kit includes two extension tubes and a dew shield so you can start imaging right out of the box.
