This coma corrector, inserted into the focuser in front of the camera, corrects the image and doesn't reduce the focal length of the telescope. A broad 44mm diameter circle, which covers a 36mm x 24mm full frame DSLR, and delivers sharp images over the entire imaging field. The Baader MPCC Mark III Coma Corrector is equipped with Phantom Group© wideband multicoating on all air to glass lens surface.

As of no surprise the view was cleaned up nicely. 5 being the minimum before coma bothers them. So even if you have a more expensive parabolic mirror in your telescope, you still need a coma corrector. Sky-Watcher Australia Telescopes Mounts Accessories. It helps astro-imagers improve their photos of the sky. Summary. Phys. This will produce the same kind of "WOW" factor as going up in aperture-- the difference between corrected and uncorrected is just that big of an improvement. Newton telescopes, with such a short focal ratio, are free from field distortion and the astigmatism is not particularly strong. Concept: I have built Newtonian reflectors since my high school days and still enjoy observing with Dobsonians.   This Sky-Watcher coma correct This f/4 scope NEEDS a coma corrector. Its four element design yields a superbly corrected field with coma correction right to the edge of the field. All correctors have sufficient backfocus to be connected to all popular camera systems. I am not happy with the focusser that is mounted at the BS, it can carry only 2,5 kg and for heavy cameras it is not able to use this camera. He has contributed images to DSLRs, I recommend the coma corrector, which produced sharp, full-frame images Coma is a common plague of the Newtonian reflector design, and its annoying presence at the outskirts of an image can be a bane for astronomers of all levels. I went through each of my subs in DSS and discarded all egg shaped stars and satellites. Tele Vue offers us a coma corrector specially designed for high quality Newtonian telescopes and astrophotography. 5 and f4 becomes f3. Folks argue around f/4.
