First attempt at NB and Clipped Layer Masks

[pmrid (Peter)]

OK. This is a first. I expect criticism. But here it is anyway., It's just an M20 that contains an hour each of Ha, OIII and SII in 10 minute subs.
Getting used to the Hubble palette takes a little while but ... I decided I couldn't possibly go to the AAIC unless I had at least done some basic colour mapping. So here it is. EdheHD14" at F11 with OAG and ATIK11002M.

Hey Peter, fantastic processing! You've got a couple of hot pixels and a bad column that you need to reject in your data. There are many ways to do this. CCD Stack has rejection algorithms to take care of this or you can dither your subs so the line doesn't fall in the same spot in all your subs. Also Nebulosity can build a bad pixel map for your CCD so you can reject these and interpolate them prior to stacking. Top work.
