Beautifully built and a pleasure just to hold. The flattener is adjustable and also has a very smooth camera rotation ring and in-built filter thread so it really completes the Zenithstar to a very satisfying unit. Because of manufacturing delays I received my scope weeks before the flattener and wouldn’t bother using the 73 without it if, like probably most people buying WO, used for photography. Stars are pin-sharp from edge to edge but without it looks terrible in the periphery. Highly recommended

William Optics Adjustable Flattener for Zenith Star 73

Wow what a difference this Flattener has made.Typical of WO the build quality is first rate,it really is a solid piece of construction.The added beauty of this little gem is in the title,adjustable.
No more messing around with spacers(unless of course your camera requires more back space than the adjuster can give,but i would think that would not be the case.
Also because everything is screwed to the scope,no more sag that can be introduced with thumb screws.Required back space is so easily done.
I can thoughly recommend this Flattener for your Zenithstar 73.
No regrets with this purchase,and of course the exerllent service provide by Firstlight Opics.

This is a superb flattener, it is beautifully made and the ability to adjust it without resorting to spacers is a massive benefit. Combined with the ZS73 I get perfect stars from corner to corner so very impressed.
