This is what you need i believe...its an m42 to 1.25" short adapter...your camera is way too far from your focal point. Unscrew the long tube, make sure its an M42 thread (the diameter of the tube should be just about 42mm) If its 42mm...buy that adapter, if its an M48, then look for an M48 to 1.25" adapter adapter
