Okay, I admit that the subject line is slightly misleading. I worded it to imply that I'm looking for a guide because I figured more people would read it. That said, this is actually about writing one. I've been thinking about a long-term project (as in several months) I could to which would be to write a book-length guide for digital astrophotography with a reg'lar consumer camera (covering both P&S and dSLR as opposed to $50,000 CCD chips). I was just starting to seriously think about doing this tonight when I thought to do a quick Amazon search. I found several books that cover this (like this book, this one, this, or this). So now I'm kinda put-off from the idea of doing it. All of these books are 200-400 pages or so, and they seem to cover A LOT of stuff, pretty much everything I was going to cover. I was planning on including stuff like: how your camera works how a digital detector works sources of noise and how they behave levels explained curves explained exposure (shutter speed, aperture, ISO) explained what you can photograph with what specifics on photographing the moon specifics on photographing star trails specifics on photographing constellations and general wide-field astrophotography photographing planets how to take pictures for astronomical image processing how to process photographs in theory how to process photographs in practice with Photoshop CS2 or 3 why webcams make better cameras for planets and other stuff So yeah, it was going to cover a lot of information, basically from start to finish, from theory to practicality ... but then again, it seems like lots of other folks have covered this, too. So is this a worthwhile project? Or would I be re-inventing the wheel? Edit: I think this guide would talk more about what you can photograph with different levels of equipment than others, but I'm not sure because I've never actually bought one before.
