Very easy to install, gives you a great guide scope.

Very useful adapter, has a great grip too.

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.

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.

Did the job perfectly.

Very well made little adapter, good quality and fit.

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.
