This actually is a work in progress with the QHY8.
I took 14x5 min shots last night using an old Celestron C8 (orange tube) with a Lumicon focal reducer from the heart of Brisvegas with all its light pollution and that stupid tower with its 4 laser lights sweeping across the field of view every 5 seconds. Someone ought to boil that cretin in crushed scorpion juice for being such a moron in this time of saving energy, year of astronomy etc etc



(rant off).
The scope has no coatings etc but it gave me the scale I wanted. Im going to gather more data next weekend to smooth it more as well as using a 10" to get more inner detail in the galaxy. Processed levels and curves in PS with no sharpening as yet.
I'd like to thank the QHY users (and others) that gave me tips on flat fielding as it really has cut down on my learning curve.
