For long, guided exposures of deep- sky objects, do you guide manually, or use a CCD autoguider?
Part 2: Do you guide through a seperate guide scope, or off- axis?
Part 3: If using a seperate guide scope, how is it coupled to your main telescope?
Part 4: Realizing the size of the target determines which method you use, would you rather shoot piggy- back, prime focus, eyepiece projection or afocal coupling?

Hi. I have a tracking scope aligned to the north celestial pole. Some shots were guided using an off axis guider (Spectrascope, I believe. Looks a lot like this http://www.mistisoftware.com/astronomy/images/GiantEasyGuider_800.jpg ), some were mounted on axis, and some were attached to the scope fork. I am a fan of prime focus.
