About this product

Model:  ae_adptr_1026

Enables you to fit a guide camera with C 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. 

Can also be used on right-angled finder scopes but will then require a suitable 'C' extension to provide the necessary back focus.

High quality, CNC machined, anodised aluminium.

Includes a handy tool for inserting / removing the adapter.

  • Overall Length: 15mm
  • Finder Scope Thread: M51 x 0.75
  • C Thread: 1" 32 TPI

Note: Finder scope threads are fine and often have small particles of paint/plastic in them so we recommend cleaning the threads before screwing on the adapter. Please take your time, be careful and and don't apply force.

Great Product!
23 February 2023  | 

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!

Focus issues
20 October 2022  | 

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.


There are 4 main causes for focus issue in this setup:

*Not screwing the adapter in to the finder scope far enough - it needs to go all the way in as far as you can. This can sometimes be tricky because of the fine threads and sometimes there can be paint in the threads so it can take a few attempts winding in / out to loosen it all up.

*Having an additional extension on the 120MM Mini - make sure you just have the C adapter on the camera, no other extensions.

*Trying to focus during daytime on something not at infinity - these will only work at infinity.

*Tolerances in the finder tube length - unfortunately we have seen some small tolerance differences in the lengths of some finder tubes which can cause issues.

Does the job

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.

Good adapter
04 February 2021  | 

This adapter does the job well, it married up my Skyris 132c to the finder scope perfectly. My only niggle, is it could do with having a shoulder with knurled edges to help with installation and removal. Nonetheless it does the job well.

Well made item

Nicely made and finished adapter. The thread that goes into the finder scope is very fine and was reluctant to screw in but a clean out of the thread on the finder scope and a touch of lithium grease soon sorted that. Superb service from FLO who were very efficient and patient with my queries.

Tight fit
11 October 2018  | 

Like the description says, the very fine thread can be an issue! I fiddled around for 30 minuttes before i found myself some grease, after that i had no problem making the adaptor fir my 9x50 finder scope!

As always great service from FLO!
