Messier 51 in Canes Venatici 2020-03-15
Aberkenfig, South Wales
Lat +51.542 Long -3.593
Skywatcher 254mm Newtonian Reflector, Olympus E410 at prime focus. EQ6 Syntrek Mount.
Better known as The Whirlpool Galaxy in The Constellation of Canes Venatici.
A fairly reasonable outcome for such an ambitious target in a light polluted location. A demonstration of what can be achieved just using an old digital SLR and a 254mm aperture telescope. A dedicated deep sky imaging camera using longer exposures would be a better option though.
A night with good transparency enabled the exposure times listed.
5 light frames of 60s at 1600 ISO.
24 light frames of 60s at 800 ISO.
Also 5 dark frames.
Processed with Deep Sky Stacker and final levels adjusted with G.I.M.P.
