This is a mosaic of two frames taken Saturday night last week. The object doesn't quite fit my field.
approx. 15x600s calibrated Flat field + Bias in CCD Stack. QHY8 - G11 - 5" celestron - autoguided PHP/ED80. Gain:1 Offset:60. Baader UHC-S + MPCC.
I was a bit dissapointed given the total integration time. I was expecting more. Clouds and sky glow, haze did a bang up job. Bit hard to process the gradients. Definitely will give it another go under much darker skies and better conditions as it was a bit low on the horizon.
Also got a lot of dark streak and noise due to fairly warm night and what I believe may be due to fast read out on the QHY8 camera. I'll try again with slower download speed. Never had the problem before. Might be temperature related.
