Description

M51 whirpool galaxy cropped close up!! Version in ha and RGB 21hours of integration with 10" newtonian astrograph
Instruments used sw Quattro 250p astrograph Newtonian at f3.8 camera asi1600mm and asi120mm with a 60mm guide scope at f4 for guiding and antlia LRGB and ivur cut filter from Optolong zwo filter wheel zwo auto focuser eq6 r pro amd cegm dx and used the sharpstar 2” coma corrector and scientific x2 focal expended and having nice pin point stars all around the edges the trick to Astro is exposure time the longest the better results I used unity gain of 139 and gain of 75 offset 50
