Skywatcher Coma Corrector 2" for Newtonian Telescopes

Optimised for all Sky-Watcher fast-ratio f/5 Newtonian Reflectors / Dobsonians, with 2” focuser.
Delivers stunning wide-field views with pinpoint stars to the edge of the field. Magnification remains unaltered.
Supplied complete with necessary adaptors for visual use.
For imaging use with a DSLR camera, a suitable M48x0.75 adaptor is required to match your camera.
Sky-Watcher manufactured Canon and Nikon M48x0.75 adaptors are available (prod codes 20237 for Canon EOS & 20238 for Nikon cameras).

As noted above, it has been optimised for telescopes with focal ratios between f/4.5 and f/5. We wouldn't recommend to use it with Newtonian telescopes of faster ratio, e.g. f/4 and faster...
