Conditions were remarkably pleasant last night and allowed first light of my new QHY600m-lite CMOS camera.
There are many bouquets and brick bats I could throw at QHY, but for now I'll refrain and simply say, while the overall experience was very positive, but at low flux levels, unlike CCD's, with CMOS low-level pattern noise needs to be worked around.
First light image is here
No noise reduction or sharpening was applied to the image stack. Darks and Flats both applied.
For those who are interested, I'm happy to field questions about the QHY600.
P.S.
Curiously, with my CCD based cameras Cosmic ray hits were common seen when collecting dark frames. I would have thought sCMOS would also detect these interlopers. Nup. Not a one. Very mysterious.
