ETX Rear Cell Thread Adapters with 2" SCT Schmidt Threads,
for Original ETX scopes and the new Observer ETX series.
For ETX-90, 105 and 125, and it fits some other scopes, see below!

This fits the threads on the rear cell of the ETX 90, 105 and 125, and has male 2" SCT
Schmidt threads so you can use your SCT adapters and accessories on your ETX.
If your ETX has male threads on the rear cell that measure 1.36" or 35mm then
this adapter will fit. Meade discontinued their adapter so we make them now here
in Texas! Machined 6061T6 aluminum, black anodized, 0.375 overall thickness

The adapter is only 9.6mm thick (or long), saving in-focus distance and space
where the camera lives. Adapters and diagonals with SCT thread collar rings
will work with this adapter.

The inside diameter is 34mm, the light path is not choked down where full
illumination of large camera imager chips and focal reducers is important.

#ETXA Fits some C90's, but only those with a visual back that measures 34.5mm!
Also fits Celestron Nexstar SE4! (If it measures ~~34.5mm diameter)
And it fits the new Meade Astro ETX-90! (because it measures ~~34.5mm...)
Also fits the iOptron MC90 Mak, photo below. Thanks to Jim T!
