I was just given a great little gift, a Celestron Nexstar 90 SLT. I really need to know what adaptor kit I need and also advice on shooting via the setup. With the kit will there be vignetteing? Can I view via the lcd screen? I'm not finding a whole heck of a lot of info on this with my telescope or my t2i.
If no one comes along with a good answer, I have a friend who might come up with something, but he's not on this forum so I'll have to ask him by email.
I have a Celestron spitting scope (more suited to terrestrial use like birds and wildlife ) and with a T mount adapter on my T2i I can remove the eye piece from the scope and mount the scope to the T mount. I'm not sure if that would work with your model of scope. There is vignetting, and I think the scope acts like an f.11, and I actually found I get better results from my 300 mm zoom cropped than I do from the scope set up.
I have seen and heard about the vingetting, but with a good shot it can be cropped out. I agree with terrestrial shooting I use my 300mm lens and it's great, even for moon shots. But I'm looking for more. Saturn, Mars, Venus, etc.
I actually just gave away a telescope for the same reason. It was kind of a toy telescope, but a quality toy; I definitely got a better image from my zoom lens. Your Celestron (Todd) may be better than that.
