This is my first post, so hello to all!
Recently I purchased an IMX533 based color camera to play a little with EAA and live stacking because I have never done that before. I plan to use it with SCT 8" mostly, and also with SY135 to try some wide fields as well, but for tests, I have attached it to my 90mm refractor.
It was windy last night and some high clouds were present, but I captured some first lights
The first one is M45 - 60x4s live stack with flat frames calibration only, so I needed to remove a few hot pixels because the Saturn C camera is not cooled - I wanted to have a lightweight and small camera.
I started live stacking too early and you can see some stars are horizontally elongated.
Another one was M33 galaxy - 100x4s stack.
And NGC891 galaxy with Abell 347 cluster left and lower from the center. It is 150x4 stack.
All stacks were shortly processed in PixInsight (color calibration, stretching, and noise reduction).
I am quite happy overall with these first results, and SharpCap autofocusing, plate solving, and live stacking with alignment and calibration worked well for me. I only need to prepare the dark frames for the next time and try with a sigma clipping stacking.

Hi Jolo,
Very nice images.
Amazing what a 90mm scope can do if coupled
to the right software and camera.
Keep up the good work.

Re: First EAA images from 90mm scope
Thanks!
I just realized I did not provide more details about the setup. Refractor is TecnoSky Owl 90/540 with 0.8x FF/FR on EQ6 mount. My home location's sky is usually around 19.50 mag/arcsec2. Camera settings were: mode RAW16, gain 150, offset 100, stacking method: average, master flat present but no master dark.

Hi Lucas and welcome
Some nice first light captures there, especially with the relative short exposure times.

Very nice start with the scope. You are doing well to be imaging at all at the moment-skies here difficult. Tim

Thanks, Tim! There are also mostly clouds at my location at this time of the year, so a quick EAA session is very helpful for health
One more stack captured with SharpCap and processed in Pix - Double Cluster in Perseus - 80x8 seconds at gain 150, with darks and flats.
Full frame 50% resized, and crop 100% size.
