I would say this is my first real astrophoto, since the previous ones were done on a tripod.

I managed to capture some of the emission nebulae despite my camera being stock. There's definitely more h-alpha data in there, but it's all mangled up with the noise. I had to use f/2.8 to shorten my exposures, which introduced a little coma. I brought out what detail I could, and I think it turned out pretty well.

Take a look!

Wow, CG-4? Was this hand guided?

Beautiful job.

What a great looking pic... All on a CG4 with a stock DSLR! Congratulation.

Thanks for the comments. Next photo I'll hopefully be using a new Sirius mount. The most frustrating part was that the red histogram never completely separates from the read noise when you've got a stock camera. Need to see about getting it modded soon...

No, I did not use guiding. The exposures were only one-minute, which I do not think is a big deal for 50mm focal length. Alignment only needs to be moderately accurate, and periodic error shouldn't be too noticeable.

Great job - that's really inspiring, I'll have to give that a try sometime.

Nice wide field image, Barnards loop included.

Have fun!
