All of my previous imaging experience lies with DSOs, and I'm aware that planetary imaging is an entirely different ballgame. My Mak127 (f/12) will be the OTA of choice (this won't be changing anytime soon) for this task, and I'm looking to acquire a color ZWO camera that will be ideally suited for use with this particular OTA. I'm aware of the pixel size (um) x 5 is the optimal focal length for proper sampling, and I've been looking at two particular cameras:
1) ASI224MC - pixel size 3.75 um, max FPS 150 at full resolution
2) ASI290MC - pixel size 2.9um, max FPS 170 at full resolution
Initially I was gravitating towards the Asi290 before I became aware of the "x5 rule", as I'd naturally assumed smaller pixels would provide a larger perceived image (as would occur with DSO imaging), however when looking at the numbers am I wrong to assume that I'd be best suited imaging with the Asi224 and pairing it with a 1.5x barlow to image at f/18?
This was my first attempt on Friday 6/14 from Northern NJ with the Mak127 paired with a Celestron 3x barlow and Canon T3i. Capture in BYEOS (1,000 frames), Stacked in Autostakkert 3 (best 50%), Processed in Registax 6.
Thanks in advance and clear skies!
