I purchased this item getting prepared for future modification of the Finder scope into a Guiding scope.

Great Product

Bought this adapter to mate a ZWO 120 Mini to my old blue 9x50 - works a treat!
You need to remove the black 1" or so extension from the ZWO to achieve focus. Careful not to remove the shallow sensor cover with it.
I'm now using my 9x50 finder for solar guiding (with OD5.0 solar film over the 9x50).
A great little adapter that opens up so many possibilities.

I searched for quite a long time for the parts I needed for my setup I kept coming back to FLO and this was one of the final pieces. The item was well wrapped and had all the pieces needed for assembly.

When I first got into this hobby more than 4 years ago I tried to convert my skywatcher finderscope into a guidescope. The previous adapter was not quite the right depth and I could never achieve focus. I'm now in the position to run two setups at once and needed another guidescope so I took a gamble on this adaptor. It allows the ASI120MM mini to get closer in than the previous adapter I bought and I was very happy to see I was able to focus and achieve sharp stars with this adapter. It yielded a 178mm focal length and that is fine for my needs. Certainly cheaper than a new guidescope. Usual FLO service was delivered super quick!

I connected and focused the ASI 290mm camera without any problem!

I ordered this item around 3pm, and it arrived the very next morning! The product itself is well made, and does it's job perfectly. I did actually have a bit of a panic at first, after thinking it didn't fit my ZWO ASI 120MM Mini Camera, but all it was was I'd forgotten to fit the little ring adaptor that comes with the ZWO Camera! Overall very happy with service and product!

I purchased this adapter to fit my asi 120mm mini camera to my S/W 9x50 finder scope. But found I could not get the camera to focus without being able to shorten the length of tube, by removing the focus lock ring to get the inward movement required to obtain focus.

Usual prompt and well packaged service from FLO. Adapter does the job, fitting securely into both finderscope and ASI120MM-MINI camera with nose adapter fitted.

Unscrew back of Skywatcher or Celestron 9x50 viewfinder. Replace with this adapter and BOOM! Super light guide scope. I bought for my Skywatcher but did my Celestron instead. 2 minute job no problems.
