it's going to be hard work imaging DSOs with that scope George. At f10?, the sensitivity will be super low (particularly if you will be using a DSLR), which will mean that you need long exposures. Agree with other posts - you will definitely need a guider and you will be limited to a few of the brightest objects. Looking forward to seeing some images.
