40d astrophotography
Going through my logs I see a lot of interest for Canon 40D astrophotography. Astrosurf has posted an informative article about faint light application of Canon 40D applied to astrophotography. The article also provides noise and electronic gain comparison of Canon 40D, Canon 20D, Canon 400D and Canon 350D. Read the 40d astrophotography article.

Canon 40D astrophotography
Recently, I posted a video about canon 40d astrophotography using the live view. Yesterday, I saw quite a few hits from people searching for ["canon 40d astrophotography"]. Therefore I thought, I'd compile a list of resources that will help you use your Canon 40D for astrophotography.
What is astrophotography? "Astrophotography is a specialized type of photography that entails making photographs of astronomical objects in the sky such as the Moon, Sun, planets, stars, and deep sky objects such as star clusters and galaxies," according to Wikipedia.
Many professional and amateur astrophotographers have published their work online. Jerry Lodriguss keeps his astrophotography collection online. He also publishes A Guide to Astrophotography with Digital SLR Cameras.
Christian Buill posted an excellent and detailed review of canon 40d astrophotography is available in both English and French. His tests found that "For the same exposure time and the same ISO sensitivity, the 40D image appears 4 time denser than the image 400D (but the noise increases also a little less than one factor 4 in the image of the 40D compared to the 400D)." A concise summary of Christian's review is available.
Another very informative resource about Astrophotography and Canon 40D is an article by Jeffrey R. Hapeman. Jeffrey covers basics of Long-Exposure Astrophotography. It is a very well written article and highly recommended.
There are so many informative resources about Canon 40D and astrophotography. I plan to post more in the near future. If you know of any great astrophotography resources, please write a comment.
