I'm still trying to get me head around these CMOS thingies. The sensitivity and resolution of the QHY600m is quite remarkable. But the noise floor still remains slightly problematic.
This image is a Sigma rejection sum of 10 sub five minute sub exposures, but as no attempt was made to register the field over three nights, the data was dithered and drizzled all by itself (I had to crop the image due nil overlap in places)
My KAF16803 CCD would have delivered a much smoother background, but no way would it resolved the extent of 47Tuc's halo as well..9 micron pixels look blocky at this FL.
I've uploaded the image at 4k resolution....looks very nice on a 4k monitor
Sorry, no colour, late evening clouds have foiled the colour data three nights in a row...
