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.

Sky-Watcher 9x50 Finder to C Adapter
26 April 2024  | 

FLO is one one of the few places in the world, apparently, that this item is available. Top notch service and an easy to use website made my purchase easy. The shipping was very fast. It arrived even faster than some items get delivered from the west coast here in the US. Thank you!

Works with the old blue 9x50 finders too!
28 June 2023  | 

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.

Just what I needed
11 June 2023  | 

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.

Does what it says on the tin!
13 May 2023  | 

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 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
24 March 2022  | 

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.
