I've been back into astrophotography now for a couple years, getting better all the time. My processing tool of choice is Pixinsight. My camera is a sbig STXL16200 with it's 8 position self guiding filter wheel. Astrodon LRGB, 3nm Ha,Sii and Oiii. Currently have a Meade 12" F8 acf, William Optics FLT156 and a Stellarvue SVX80t.
