First light with the new ZWO ASI 183MM Pro CMOS camera. The tiny 2.4um pixels allow very high resolution captures even with moderate focal length telescopes. Tight crop on M101 to show the captured detail. I have to experiment a bit more with sub-exposure duration and gain/offset combination but very happy with the first two nights of data.
