Good quality product

The adjustable flattener has the usual William Optics quality feel about it. It gives secure attachment for my Canon and Fuji cameras, when used with the appropriate adapters, and has allowed me to capture crisp images now that we have finally had some clear skies.

Does the job

It works fine, does what itís supposed to do. The tension screws really need unscrewing a lot before it can be rotated to set the framing angle but once discovered, it does work. It would be useful if either William Optics website or FLO mentioned that rotation was possible and how to do it.

William Optics Adjustable Flattener for ZS 61.

I bought this Flattener as it has been designed for the above scope,and could be directly screwed directly onto the scope,theifore eliminating any slippage, or off axis alighnment that can occur when using a flattener that is a push in and grip method.
Again with WO the fit and finish is second to none,and the adjustabilty to be able to set easily the back focus is a real game changer.
Another nice touch is that the Flattener can also be rotated in order to be able to frame your targets better.
I would,nt be without it,and to me it justifys the extra cost ,and i can thoroughly recommend it.

I've used cheap third party 1x flattener before and couldn't get field corrected on APS-c size sensor. I've decided to buy dedicated one. What a difference. Perfect stars across the field of APS-c. Will try with full frame soon.
Don't hesitate. Get one for yourself
