Hello everyone , I own a celestron SCT 8" with reducer 0.63. Can I achieve a goof focus using ASI 224MC color as a guide camera with ZWO OAG and Helical focuser 1.25" or OAG uses only mini cameras ? At the back of the OAG I use a filter drawer 18mm and main camera ASI 2600mc pro color . Please advise !!!
