M33 and the Crab with the 10" RCT

Recommended Posts


after my "pop-art" mishap (see http://stargazerslounge.com/imaging-deep-sky/164806-m33-pop-art-little-mishap.html ), now an M33 of two nights. Altogether 57 x 2 min, GSO 10" RCT with optimised baffle, modified EOS40D camera, EQ6 pro, no guiding.

Stacked with DSS and contrasted using Canon Digital Professional.


Yesterday in a cold, transparent and windy night, I got 35x 2min on the Crab nebula:


I had to shut the obsy after that as it started to rain in strong winds while the sky was still mostly clear !

Hi Mark and Telrad,

thanks for your nice comments. It was my first trial on M1 yesterday with the RCT - until now my best shot was with a Celestron 9.25 from Kielder, but only 1/2 hour. So it is getting better already, but this object still needs photons. Also I am restricted to short exposure times as I work unguided. Here an autoguider should step in shortly.
