March 3, 2022. M42. Celestron 6 inch SCT with Starizona 0.63x reducer/corrector. 150mm aperture at F6.3 giving 945mm focal length. Canon full spectrum full frame EOS 6D. EQ6-R Pro mount. Sky Watcher Evoguide 50 ED guide scope with ZWO ASI120 mini guide camera. Guiding via PHD2. DSLR lights plan executed in AstroPhotography Tools (APT). 30 exposures of 30 seconds each. 15 minutes total imaging time. This was basically a test of my guiding setup. Unfortunately I discovered that my coma problem with the C6 was not cured by the more expensive Starizona reducer/corrector and apparently is as severe as with the Celestron focal reducer. This is why I prefer refractors or refractor lenses. If it were not for the coma, the C6 would be a dream scope.
