GSO photographic coma corrector for Newtonian telescopes. 1.25" corrector, designed specifically for the GSO 4.5" F/4 M-CRF-D Reflector Carbon (SKU: GS280) and other telescopes with a 1.25" focuser, for which two-inch correctors cannot be used.
For focusers with a smaller shift range, in telescopes with a shorter working distance, it is recommended to use a 1.25" 25 mm extension with a double-sided M28.5x0.6 thread (GSO FF519) in order to seat the corrector deeper in the focuser (it allows you to shorten the back focus from 72 mm to 47 mm). • Diameter: 1.25" / 31.7 mm
• working distance / back focus: 72 mm, counted from the beginning of the external thread
• camera side mount: external thread (male) M28.5x0.6 (1.25" filter thread)
• total length: 56 mm
• weight: 81.6 g
