Orion sells an adapter for its Maksutov scopes that will fit this Celestron. With the adapter ( about $20) all SCT accessories will work on this Celestron.
Bought for a spotting scope for shooting. 8x21 Erect Image Finderscope was useless in locating target. Had to move scope around alot to find. You definitely need a heavy duty tripod with a solid base to use this. It shakes ALOT on a std camera tripod. I also tried to use it to look at stars, but did not have the proper filters to do so. This scope may be more than I need for spotting targets. Eye piece would be better if it had a rubber cup. Was difficult to look thru.
Returning from France I decided to get a telescope for a friend there. Talked to several people including my friend..i came to same conclusion he did, for the money, you get the best of everything with use of both kinds of lens and a very strong name brand. Though i did not "ck it out" all the reviews, etc. gave this scope very good ratings.
this scope is awesome..i need to get a sturdier tripod..
