Observing Report 3rd-4th May 2011 (A Cluster and a Ring)

Posted by on May 5th 2011 in Astrostuff, Observing Reports, Pics

I'll spare you the usual details, suffice to say that it was a warmish night, nice and clear and with a light breeze so I was out with the baby R-C scope looking at more Messier Objects. It was a late start and a short session, as from 4 a.m. onwards it was too light to take pics.

As before, I'll let the results do the talking:

M10 (aka NGC 6254), a globular cluster in the constellation Ophiuchus.
Subs: 7 light @ 300s, darks and bias frames, ISO400.
1000D on the 6" R-C, guided with PHD.

 M57 (aka NGC 6720, The Ring Nebula), a planetary nebula in the constellation Lyra.
Subs: 16 light @ 300s, dark and bias frames, ISO400.
1000D on the 6" R-C with 2x PowerMate, guided with PHD.

 

M57 really needs a lot more data, I'll try to get more next time out.
