Helix calibation used
Hi
I've reprocessed the Helix from a few days ago using better calibration techniques of dark subtraction, blurred background lighting removal, white and dark point settings etc
more time consuming but better than my previous outcome from one long 20 minute exposure.
10X 483" ISO 800 C9.25 F6.3 CG5 autoguided EOS 20Da (with a nice clean sensor now)
cheers
frank
