Observing Report 2nd-3rd March 2013 (A mixed bag of Messiers)

Posted by on March 4th 2013 in Astrostuff, Observing Reports

It wasn't forecast to be the clearest of nights but I'd got the OK to go out and I wasn't going to waste the chance. The skies were fairly clear for the first hour but after that I was battling the orange haze of a low thin mist illuminated by waste light from streetlights. Despite that, I managed to see a fair few things and snap some more Messiers:

M40 (centre-left), a pair of stars in the constellation Ursa Major.
Subs: 12 light @ 300s, darks and bias frames, ISO800.
1000D on the 6" R-C, guided with PHD.

M48 (aka NGC 2548), an open cluster in the constellation Hydra.
Subs: 16 light @ 300s, darks and bias frames, ISO800.
1000D on the 6" R-C, guided with PHD.

M53 (aka NGC 5024), a globular cluster in the constellation Coma Berenices.
Subs: 22 light @ 300s, darks and bias frames, ISO800.
1000D on the 6" R-C, guided with PHD.
