I've seen some photos of nebullas, galaxies etc... do you capture them with a 70-200mm lens :o ?? Or do you attach a teliscope to your camera? Thanks guys...dont have an idea how much the 70-200mm lens zooms that's why!

Moved your post to the "Technical and scientific photography" section, because here are all the threads about astronomy collected together.
Do screen them, there are excellent threads! And have fun...

Have a look at the thread Gibbous moon handheld shot at 300mm !. The third post includes an image showing how much (or little) the Moon fills the 400D sensor when used with a lens at 300mm.

Hi kno3,

I've edited your message to get rid of that horrendously long link which was breaking the page frame. It's also more user friendly now. Click the Edit button in your post to see what I did.

As I indicated in my PM, your first and most important task for shooting anything other than the Moon is guidance. That pretty much means a motor driven equatorial mount. Personally I would avoid the item you linked to unless you wanted it for something else. I have no way of knowing what the quality of the optics is like but bear in mind that stars are just about the most unforgiving subject you can choose.

If you are new to the subject you could do worse than have a look through some of the articles accessed from this Sky & Telescope page.

It's a steep learning curve but it's very satisfying when you get it right. 8)

Bob.
