The M51 galaxy, 31 million light-years away from Earth, is a spiral galaxy visible to the inside of the hunting dog constellation. Recompile a photo made in March, but with the difference that this time I used the Drizzle algorithm that doubles the size of the photo. Although the total exposure time is poor (only 11.5 hours of laying), some emission nebulae are also noticed. Setup used: Newton Sw 200/1000 with Mpcc 3 mounted on a Neq6 Pro frame, sum of 139 poses from 5 minutes to 200 iso made with a Canon 1100d full spectrum reflex
