Description
(Ha)GB composition of 10x20min RGB unfiltered images and 8x20min Halpha (Astrodon 6nm) @ ISO1600 Suburban sky, with 6.0m visual limiting mag. Canon 350Da(mod) with 4.4(D=110mm F=800mm) Newton reflector on EQ6Pro Syn Scan mount, autoguided. Processing - Iris & Photoshop. Low outdoor temperatures (-17C when taken RGB and -5C for Ha images) makes DSLR almost like cooled CCDs :-D, so such long expositions with high iso settings became possible.
