after being out of EAA for the past 3 years I admittedly jumped on a few familiar purchases and a few hype train products. a c6, avx mount a 224 camera and the night owl.
using SharpCap and my prior knowledge I was quickly able to produce satisfying images without issue. my only issue was the FOV since the size of the sensor was only 6mm.
after a few months, I danced between the 183 and 294..the night owl was designed with a 183 sensor size (16mm) in mind but I wanted BIG..BIGGER IS BETTER RIGHT??
so I purchased the 294.
the 294 was even easier to setup since it came with all the exact sized spacers I would need for back focus from the night owl..perfect
I started it up full frame..HIGH REZZZ...sharpcap polar align was a breeze with this 23mm chip..it saw like..like..the universe almost !!
but it also saw vignette and coma and the occasional sct things like some reflections from the reducers or internals or whatever..idk..
I COULD NOT GET A FLAT FIELD..TOO MUCH VIGNETTE TO GET A GOOD FLAT>>BRIGHT CORE OR EDGES
so then I dabbled with the celestron 6.3 reducer and had an amazing 3 nights in a row of EAA..I saw little things and big things..things I've never seen before!!
BUT the edges were even worse but the vignette was managed by a flat.
so then I reached out to starizona and they gave me the tested resolution size for the night owl and a 183 and 294 sensor..the size doesn't fit one available in SharpCap so I settled on
3104X2116..they recommended 2848w by 1952h
flats corrected the vignette (1.5s) keeps the core tame so it doesn't blow out during a stretch and the corners are nicely blended. a few edge areas show some needed help but its just the limit of what I am working with at this point! the 294 camera is just super amazing and the night owl reducer is proving a great option! a 224 at $250 is super as well and will service me for planets.
ill provide the images here and it should be fairly obvious what is what but feel free to ask any questions! I was tempted to sell the scope and reducer and try another combo but now this system is proving to work great and the 294 is of course very flexible for any wide field scope that I will be adding in the future.
