if you are trying to do high resolution planetary imaging at long focal lengths with a small CCD, finding the object can be a real pain. Try setting the camera to relatively long integration (eg a second or two) and maximum gain and then defocus the scope enough that the star/planet images expand to be larger than the fofv, but still visible - quite often you will then be able to see part of the extended image of your target if it is bright and not too far away - easy to centre then.
