some folks may be interested in these early results from my new (secondhand) QHY9 CCD. still got a lot to learn about the world of CCD image capture and processing but starting to get some decent results.
the main image is about seven hours of h-alpha and forty mins each R/G/B and Luminance. Black and white h-alpha version

for interest, i've also attached a quick and nasty crop comparison with a Hutech 20D version taken in 2007. the images are totally different.. QHY9 on the left is 8 hours total, mainly h-alpha (more fine detail) while the 20D is about 4 hours broadband colour. QHY9 image has not been processed for such rich colour, but the inherent noise of an uncooled DSLR is still quite striking compared to the smooth tones of the QHY9 CCD.
