About this product

Model:  lynxastro_sw_9x50_finder-t_adptr

Enables you to fit a guide camera with T 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 you will need a 40mm T extension to provide the necessary focus. 

High quality, CNC machined, anodised aluminium.

  • Overall Length: 12mm
  • Knurled Grip: 2mm
  • Finder Scope Thread: M51 x 0.75
  • T Thread: M42 x 0.75

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.

Fitting to a TS 8x50 finder
Friday, 5 April 2019  | 

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.


Response:

As you've found, these are designed specifically for the length and threads found on the Sky-Watcher 9x50 finder. They may work on others but these are the ones it's designed for and will 100% work with.

Secure fit

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.

Great Adapter
Friday, 27 April 2018  | 

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.
