Hi,

I've been considering getting at a Skywatcher 114/1000 catadioptric newtonian reflector on ebay at a pretty low price.

I was wondering if it could be used for astrophotography with a dslr? I know some similar scopes can't, at least by default. I've heard that for similar scopes modifications can be made to achieve 'prime focus', or a barlow can be used too. I'd be happy to try to modify it, if that's what would be necessary to make it work. I'd also be fine trying a barlow, even if it'd reduce the f stop- in which case, what would be the minimum magnification barlow I could use? I've heard low-profile focusers could work for certain telescopes, but I think they're a little too expensive. Would it work by default, if not would it work with one of these?

Thanks a lot.

EDIT: according to some reading up it may not be the best choice of telescope in any case. Thanks for any attention, sorry but I am unable to delete this post.

Don’t buy it. I’ve had one and the integral Barlow causes issues, as you can’t really collimate the scope using a cheshire or laser.  The 114/500 would be much better, as that’s like any other Newtonian design.

 If you want a newt for imaging then perhaps consider the SW 130pds....it was specifically designed for Astrophotography, as it has an oversized secondary to fully illuminate the field when using a camera. Someone else might be able to comment further on that, but if you can stretch to it, that would probably be better for your needs.

Staying away from it was a good decision!
