Enables you to fit a guide camera with T thread directly to a Sky-Watcher 9x50 finder-scope.
Will also fit other similar finder-scopes from Orion / Celestron with a fine M51 x 0.75 thread.
High quality, CNC machined, anodised aluminium.

Fits and works as described - no problems

i purchased this adapter to connect a new SkyWatcher 9 x 50 finder to use as a guide scope with an ASI120MM-S camera. The part had a sharp sliver of painted metal which fell off when inspected and the adapter also had a shoulder (no on the FLO image) which prevented the adapter being secured close to the camera side. It works however.
We don't often have quality issues on parts like this so we would have replaced this had you reported the sharp thread to us.
The shoulder though is intentional, it's on many of our adapters and can stop the Aluminium parts becoming jammed together which makes removal much easier.
Works with the Celestron finder scope

Fitting to a TS 8x50 finder

Very nicely made adapter can't fault the build. For me though wanting to put my ASI 120MM on to a TS 8x50 finder I couldn't get focus as the adapter came. I had to machine off the knurled section down to the thread depth so it would go further into the finder's tube. That solved it. The camera now focuses. This is probably because I had a spare TS 8x50 finder rather than a skywatcher 9x50. I think the finder tube on the TS must be a few mm's longer.
4 stars because it didn't quite work out of the box for me - had it focused at infinity it would have had 5.
As you've found, these are designed specifically for the length and threads found on the Sky-Watcher 9x50 finder. They may work on others but these are the ones it's designed for and will 100% work with.

I cleaned the thread on the finder and had no problems fitting it securely to an ASI120MC-S.
The only issue I encountered was achieving focus. This required the removal of the locking ring to allow sufficient inward travel for the objective.

I was very happy when FLO listed this adapter for sale. It is good quality and does exactly what it is needed for. I am have now been able to convert my SW 9x50 into a guide scope using a ZWO ASI120MM. Highly recomended for use with any camera with a T-thread.
