Skywatcher Coma Corrector for fast Newtonian Telescopes - 2" Connection

The aplanatic coma corrector allows astrophotography through fast Newtonian telescopes, such as Skywatcher Quattro Photo Newtonians.

♦ 4-element design for pinpoint stars to the rim

♦ Well corrected image field up to 28 mm diameter - well suited for cameras up to APS-C

♦ Optimized for reflector telescopes with a focal ratio of f/4

♦ Working distance 55 mm from the M48 camera thread

♦ The focal length of the Newtonian telescope is not changed.

 

Skywatcher Coma Corrector for fast f/4 Newtonian Telescopes

The Skywatcher telescope coma corrector, optimized for astrophotography with the fast f/4 Quattro photo Newtonians, delivers an impressive image. You can expect pinpoint stars to the edge of the flat visual field. The magnification remains the same.

The system consists of 4 lenses with one element made of FPL51 ED glass. The back focus (working distance) is 55 mm, the image circle diameter 28 mm for APS-C format. The coma corrector has a 2" barrel. To mount your camera you need an adapter from M48x0.75 to your camera mount.
