Answering your questions: The Celestron has two advantages over the Mak
as far as imaging is concerned. It is somewhat faster photographically,
and it has a wedge. Without a wedge you will be limited to very short
exposures, around 15 secs or so, any longer and the stars become
misshapen due to a phenomenon known as field rotation. With a wedge, and the scope properly polar aligned, you should get unguided exposures up
to 30-40 secs. These exposures will only be sufficient for the brightest
DSOs. Wavytone is right on the money for most DSOs, but you should be able to get some half decent lunar and planetary pics, especially if you stack short videos in Registax or similar.
For purely visual of the Moon and planets, the Mak has the edge.
