2" FSQ85 Visual Adapter (TKT37110)

The fit is absolutely perfect on the FSQ85—threads engage smoothly with zero play, and the 2-inch connection feels rock solid for eyepieces. I've spent three nights with it and the stability makes focusing a joy.

Threaded this onto my refractor for a visual session and the 2-inch connection holds my eyepieces rock solid, no wobble at all. It replaces the imaging train cleanly, so switching from camera to diagonal takes seconds now.

Snapped right onto my FSQ85 without any wobble, and my 2" diagonal seats perfectly flush now. Star testing last night showed zero flex even with a heavy eyepiece hanging off it. Exactly the clean visual setup I was after.
