Observing Report 1st-2nd December 2011 (Two more clusters)

Posted by on December 3rd 2011 in Astrostuff, Observing Reports, Pics

Another night looking at pretty much the same as before. The seeing was better but still not brilliant. Visual observations of Jupiter, Mars, Andromeda Galaxy and several star-clusters. Tried to image M97 (Owl Nebula) but got the settings completely wrong and so ended up dumping the imaging data. Managed to do better with two other Messier objects as follows:

M38 (aka NGC1912), an open cluster in the constellation Auriga.
Subs: 18 light @ 300s, darks and bias frames, ISO400.
1000D on the 6" R-C, guided with PHD.

M103 (aka NGC 581), an open cluster in the constellation Cassiopeia.
Subs: 19 light @ 300s, darks and bias frames, ISO800.
1000D with 2x PowerMate on the 6" R-C, guided with PHD.
