For longer exposures, you'll get a lot of noise in the image. The colder it is, the longer the exposure you can have, or at least that is what I have found. This shot was taken when it was below freezing.
Yep, CMOS chips get toasty after a while. Most DIY astro-photography rigs using modded dslrs add some additional cooling. I'm now awaiting an OCNer to attach a phase change unit to his/her camera.

And my contribution:
Canon 500D + 18-55mm kit lens (Insanely annoying to focus at night time, why is there no distance scale on the focus ring!?!?).
f/8, 30s, ISO 100, Shot in RAW, processed in Adobe Camera Raw.

I looked into it previously. A phase change unit would draw too much power though, most of the time I'm out in a field or something and don't have access to power other than the APC unit I bring. Using dry ice or LN2 would be much easier.

Took a pic early this morning....in the rain and with large swell almost hitting me....anyhow
HDR edit (no idea on HDR - just looked ok)
20 + 25 + 30 seconds combined

Very quickly done - if there is any advice further for it - like a good HDR program etc

Canon 50D w/ Sigma 30mm f/1.4 ISO 400 f/4.5 2"
Santa Monica, California

Not quite a long exposure, but longer than most shots I do. I've some others I'm working on. You know, when I actually get around to doing some exposure blending in Photoshop (and no I refuse to do tone mapping HDR )

This was a shot I took the other night of the moon over the water and the sun had just set, I liked the colors, but wish I could have gotten the moon sharp as well, 30 second exposure, F16, ISO 100
