I have difficulty using my STXL-1100M with SKYX Camera Add-On. The camera is not specifically listed, but I have found that the STX does work but the listed filter wheels do not match up to my choice of the FW-8S. Can you enlighten me as to which choices I should make for both the camera and filter wheel to function properly? I should add that the camera and filter wheel work well with Maxim-DL.
