I am confident on using an OAG as I have been for sometime. It took a while to get both the imaging camera (currently a QHY 163C and a ZWO OAG) and the guiding camera in focus but once set, it works well just as long as I don't look at the OAG without a smile on my face. I read that back focus has to be meticulous so it will be interesting to see what does happen with this. I primarily want to do narrowband targeting as well as broadband LRGB depending on the circumstance. One person said to crop the images to remove any rubbish from the edges but when forking out so much money, I would like to get good data across the sub.
My Optolong filters are still being manufactured or shipped, not quite sure of their thickness. I can't see the sensor in the camera but there is something there and it might be some sort of cover for it. The 16200A is all a bit high tech compared to CMOS cameras.
