Off axis guiding with a Schmidt cassegrain, any comments appreciated
I am successfully guiding my SW ED80 using a piggy backed orion short tube 80 and ASI130MM camera with PhD . How hard would it be to use an off axis guider using this camera with my celestron 9.25" at f6.3 ? Finding guide stars with the Orion 80mm and camera was very easy but I can imagine not so easy with a pick off prism as its field of view and that of the larger telescope will be much smaller. I don't want to waste money on an off axis guider if it is going to be too hard to use but am up for the challenge. Any advice would be appreciated.
