Quote: Since the threads on the Min-EQ are the metric equivalent to 3/8", I didn't know if it would be a good idea to make an adapter plate so that I didn't chew up the threads on my mount. Have you had any problems with that?
Quote: I'm torn right now between staying cheap and looking for an additional summer job (I'm a college professor in a somewhat poor state) so that I can afford a mount to last me for whatever my hobby might someday grow into. (I hate these kinds of decisions!)
Quote: Basically, I am torn between the inexpensive route to just take a step up from what I have already attempted and trying to match the capabilities of my camera/lenses to the mount.
Quote: There is no sense in going for a better mount than my camera can handle, and I don't foresee ever getting out of the "consumer line" of Canon cameras (Rebel/40D/50D/etc.).
Quote: how long of an exposure a given Messier Object (say M31 for my example) would take to get a result (depth) that was equivalent to [posted picture].
Quote: I have had others recommend EQ3 mounts and a good match for the performance of my lenses.
Quote: The reality with astrophotography is that for focal lengths 200mm and up you are going to need a stable and accurate mount. The mini-eq is really best suited for 100mm and less and that means 24mm to 50mm are more optimal. At 50mm, Jupiter is a bright star and the moons will probably be indistinct.
Quote:The CG5-GT mount is the least expensive mount you can get that will carry a nice range of focal length scopes. If you get into autoguiding, there's no reason you couldn't shoot long exposures with 1000mm focal length scopes as well as using the mount for wide field imaging with just the camera sitting on it.

If you've spent any time at all in the DSLR forum below, you'll soon realize the DSLR cameras you're speaking of are NOT THE WEAK LEAK in astrophotography! You can do a lot of serious imaging with a common DSLR.
Quote: Quote: how long of an exposure a given Messier Object (say M31 for my example) would take to get a result (depth) that was equivalent to [posted picture]. I don't see your picture, but here is a photo of Andromeda (M31) taken at 320mm focal length and comprised of 60 x 1 minute exposures. The mount was a CG5-GT mount...just for reference. The camera was a Canon 30D. The lense was an Astronomy Technologies 66mm APO refractor. A 300mm Canon lense would be more than adequate as well.
Quote: At 300mm and above, ... you wlll really want to autoguide. ... Another feature that is very useful for imaging is goto. I took this shot of the North American Nebula without actually ever seeing it in my telescope. I had to take an image just to verify that it was there. The goto on the CG5-GT mount put the nebula dead center in the field of view. In addition, some objects may require multiple nights of imaging to get enough data. Having a goto scope can really be helpful there.
Quote:That's why I say that the CG5-GT mount with full goto and autoguiding, and capable of holding a wide range of instruments is such a great deal at only $600.Patrick
