Finally Taking Pictures!

By

After trying to get the right equipment for astrophotography, this lens finally got me there. The only thing I don't like about the setup is that I cannot "zoom" in/out. The image size is fixed, but worth it to finally take some good pictures.

Questions about this item:

Shopper  A friend of mine has a celestron 8 inch schmidt-cassegrain telescope, I have a Canon 7D camera with the (canon) T-ring adapter. Will this T-adapter work on this particular scope ? I don't have access to the scope yet, but would like to have all needed acces. in hand when I do.
ROBERT B  Yes. You just use this to replace the eyepiece. The great majority of telescopes have the 1.25 diameter eyepiece, and this will work in all those, too. There are issues to be aware of. The mount of the scope may not have room for the camera, and the balance may be thrown off by the camera weight. This affects the accuracy of star tracking. The other issue is the focal planes of the C8/7D. After passing through the diagonal, there may not be sufficient focus travel to get focus to your 7D sensor. Mine just makes it to infinity. There is another option, the Celestron 93633A T-adapter, which threads onto Rear Cell, replacing the diagonal assembly, saving about 1.5" of focus. Again, there may not be room for the EOS if you point straight up. I have both of these. The Moon will be 110 pct of the narrow sensor dimension. Use daylight exposure setting - it's basically a beach scene up there. The C8 is f10.
rich k  That info is very helpful, thank you. I have ordered the 93633A you mention to cover both bases. When you mention the 110% sensor issue - would it make any difference if I used a different camera with different crop sensor? I also have a Canon 1D Mark 3 which has the 1.4 crop sensor (vs. the 1.6 of the 7D) and wonder also about any change in result (with same C8 scope) if using a full frame sensor camera - say a 5D Mark 1, 2 or 3?
