This adapter replaces the eyepiece assembly and converts the excellent Skywatcher finder into an effective guidescope by fitting a planetary camera (I use the ZWO ASI 120MC and it works very well)

Perfect fit and does the job perfectly. Fits my ASI 120 MC-s guide camera nicely.

First I could not get to focus but I did little research and what you need to do is to remove the tightening ring on the Sky-Watcher 9x50 Finder

Great quality product but it did not work with my Celestron 9x50 finder scope. Tube needed to be a bit shorter in order to come in to focus.

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.

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.
