The first astrophoto taken with the EOS-M. Considering the trouble it is to manually trigger the exposures without proper camera control, I am surprised I stuck it out to take 40+ subs. Since 30 seconds was the longest I could program the camera for I simply maxed out the ISO and took a lot of subs plus a dozen darks. There is still way too much noise in the resulting frame. Still, the ISO 12,800 frames are not all that bad, better than I expected. If this camera had remote control it would be a decent little astro camera. Longer subs and a lower ISO would deliver decent results.

One of the nice things about many of the NIkon bodies including the D90, D300 and many others is the 10-pin port that supports use of a very inexpensive MC-36 intervalometer. I’ve heard more than one Canon user lust for such an option. 🙂
That is a great picture. What brand .8x reducer did you use on the AT6RC?
I use the Televue 0.8x reducer/flattener that I use with my TV-76. Not perfect, it is designed for an f/6 ‘scope, I have considered ordering the AT reducer, but not that bad either.
