Sharpstar 3" 0.85x MPCC Coma Corrector
Sharpstar 3" 0.85x MPCC Coma Corrector
A coma corrector is a must-have accessory for those looking to use their Newtonian reflecting telescope for astrophotography. Adding this Sharpstar 3" 0.85x coma corrector to your system will allow full-frame imaging and effectively produce fantastic deep-sky images due to reduced aberrations. The 30085NTRD coma corrector can shorten an original focal ratio of f/4 to f/3.4 which greatly reduces the exposure time.
When it comes to threads, you will find many threading options with this coma corrector. At the front of the corrector, there is an M82x1 male thread that will connect to the Sharpstar 3" focuser. On the back, there is an M76x1 male thread, M68x1 female thread, and an M54x0.75 female thread. These can be used to thread onto the Sharpstar M54 to M48 camera adapter ring (not included). This coma corrector has a back focus of 55 mm, starting from the M54 camera end thread to the focal plane.
