I am adding OAG to my FSQ106. I have a SX filter wheel and purchased the SX guide head and ASI290mm mini. When I get the scope focused I can't get the guider anywhere near close. I have to move inward 600 steps for the OAG to reach focus but then the scope is way off. The stars are just long streaks when the scope is focused and PhD can't use them. I tried guiding with the guide stars in focus but the stars walk off the PhD screen. This doesn't happen with the normal guide scope.
Any help appreciated
