I got this photo last night. Good, sure but I was wondering how people got more. And by more I mean something like this..
I understand that I am not in the best of areas for astronomy photography so maybe that is my problem but I was wondering if I am just missing something.
Should I use my 50mm f/1.8 instead of my 18-55 kit lens? I wanted as much stars as I can fit into the frame but I guess it wasn't bright enough.
Thought?

Notice a few things about the example you referred to:
- Shot at f/1.8, so about 2 stops faster than yours. This is a big difference
- Carefully aimed at the central part of the Milky Way; this is an area of very dense star population
- Shot in a very dark area (but does not mean you can't get something good under less-than-perfect skies)
The key, if you aren't able to track the movement of the stars with a telescope mount, is to gather as much light as possible in short exposure time you have before stars trail noticeably. You need to keep your exposure time below about 600/FL. So if you are shooting with a 50mm lens, about 600/50 = 12 seconds is the limit, perhaps a little more or less depending on your tolerance for trailing.
There are a few old threads around here somewhere that discuss techniques in detail. Some searching should bring them up.

Thanks, I will go hunting for them after I go out with some friends.
Thanks again! :D |

Thread with additional links
This has at least some of those Fritz mentioned. A big one is shooting with a fast aperture... really makes a world of difference. Also, a sturdy tripod and a cable release help things, but you can also use your timer. |
