What does 35 min with a QHY10 get you?
Ive been trying out further FR and FF from different manufacturers on my 127mm scope to see exactly which will give me a perfect flat field with sharp stars. After testing about 7 different ones I have settled on the P-Flat IV from William Optics. Nice but expensive bit of kit.
So after testing there were a few sucker holes around and so I decided to see what I could get to the North of my site. I managed to get 7x5 min with the QHY10 - PFlat IV and 127 mm scope before the clouds cleared me out.
I reduced it to monochrome as the colour was terrible due to moon and light pollution in such a low number of subs. In hindsight I would have been better off binning the camera 2x2 but that didn't occur to me at the time. Reminds me of a sad face; no flats, bias or darks.
Comments welcomed
