I have a Ricoh KR-5 SuperII camera, celestron t-Adapter, t-mount adapter and a Bushnel reflector telescope, i know i know its not that great. I seem to be able to only focus on close objects like trees CLOSE TO ME but I cant focus on a stop sign across the street. please help me out I could realy use it. In advance Thanks!!! I wasnt sure where to post this... lol

I hope you're using just the T- Mount adapter and not the black barrel extension and you're not trying to use an eyepiece.

And if you are using the diagonal, you should take that out as well. First, because the camera will give a correct image without it, and secnd because the additional legnth that 90 degree prism adds may too much to allow you to reach focus.

You should have the T muount inserted into the tube where the diagonal goes, and nothing between that and the camera.

Think of it as attaching a 1900 mm lens to your camera - supertelephoto. You don't need an eyepiece for that.
