NGC 55 (Will the real Sculptor galaxy please stand up!?)
My Synscan handset lists "Sculptor galaxy" and NGC 253 as 2 objects. After digging about I gather NGC 55 is being called the "Sculptor galaxy". I guess they're both in Sculptor......
Anyway, as a first semi-serious DSO stacking effort thought I'd pick a bright galaxy, however I gather NGC 55 is a bit tricky from reading around tonight? Forgive my dodgey processing - trainer wheels on. Original stacked image from DSS and my attempt at processing attached.
Took about 90 x 30sec, mainly ISO 1600, some 800 with about 8 x 1min thrown in. MPCC and IDAS in use, no guiding, and oops - no viewfinder cover on....
I've fiddled quite a bit and can't get rid of that noise/sky background surrounding the galaxy without losing a lot of galaxy detail. Any pointers guys?
All done with in-camera noise compensation turned on and no darks/flats, so I guess that's one big reason.
