The Local Group spiral galaxy, Messier 33 in Triangulum, with some of its star forming nebulas showing up as green-blue Oxygen III regions in its spiral arms. This is a stack of 30 x 6-minute exposures, with the Starfield Optics Géar115 f/7 apo refractor taken as part of testing the scope, with its 1x Adjustable Field Flattener for the scope's native 805mm focal length, and with the stock 45-megapixel Canon R5 at ISO 1600. Autoguided and dithered with the MGEN3 autoguider on the Astro-Physics Mach1 mount. No dark frames or LENR applied on this chilly night in December 2022. Noise reduction with RC-Astro Noise XTerminator; star reduction with RC-Astro StarShrink. Galaxy details were enhanced with applications of: a masked High Pass Sharpen filter, Starizona's Galaxy Enhance action, and PhotoKemi Dark Details action. All stacking, alignment and processing in Photoshop.
The Local Group spiral galaxy, Messier 33 in Triangulum, with some of its star forming nebulas showing up as green-blue regions in its spiral arms. The field also contains some faint and much more distant 13th to 15th magnitude galaxies. This is a stack of 20 x 4-minute exposures, with the Starfield Optics Géar115 f/7 apo refractor taken as part of testing the scope, with its 0.8x Adjustable Reducer for f/5.6 and with the stock 45-megapixel Canon R5 at ISO 800. Autoguided and dithered with the MGEN3 autoguider on the Astro-Physics Mach1 mount. No dark frames or LENR applied on this mild night in November. Noise reduction with RC-Astro Noise XTerminator. All stacking, alignment and processing in Photoshop.
