This makes things a little easier. I previously tried the Orion thin off-axis guider; it was difficult to find good focus between the two cameras (DSLR and CCD auto-guider). This Orion imaging flip mirror is a lot easier to use and set up. I have it mounted on my guide scope – an older but rugged Meade 1980’s spotting scope. The Meade DSI II is attached. I really like the things at Orion.
