Off Axis Guiding
Im a bit confused about off axis guiding. I understand why it is needed for certain scopes, but how do you locate a guidestar. I have all sorts of trouble getting a good star with a dedicated guidscope, and I cant understand how one would obtain a good star when you can't move the scope, framing etc... I should mention im using a celestron stand alone guider. Does that make a difference? Could I use this guider with an OAG setup?
Cheers
