I order two of these and I'm very happy with them. I have both on my William Optics Zenithstar 73 III. And they fit like a glove. This product is made of aluminum. I don't think the description said that.
It´s perfekt for the ZWO Asiair plus. I really recommend this product

I bought two of these finder shoes for the same purpose. One was attached to the focus draw tube of my WO FLT120 and the other was attached to the Pro Astro Gear 3D printed mount for the Redcat51.

Installation was easy (all screws are provided) and the shoes sits snuggly on both flat and curved surfaces. There's slots in horizontal and vertical directions so this will cater for different screw hole layouts for different telescopes.

Two thumbscrews are provided which holds my ASI Air Pro nice and securely. Fully recommended!

Bought this accessory to fit to my Z73 scope as a mounting point for a ZWO ASIAR. Easy to install, ASIAR fits perfectly. An ideal addition to your Scope if you want to keep things neat and tidy with shorter rather than longer cables.

Excellent build quality and does the exact thing I need it to (allow for the ASIAir Pro to be mounted on the ZS61). Thanks Alex for the brilliant suggestion and as always, the first class quick service from FLO.

I bought this base so that I could attach an ASIAIR Pro to my William Optics Zenithstar 61 II APO. The good news is it fits and does the job but with a couple of provisos.

First, do not use the screws which are included with the base, use the screws you remove from the scope instead. For this scope the given screws are too long. I suspected that when I saw them but nonetheless did cautiously try them for fit. If screwed home they will foul the focusing tube; I now have a very tiny scratch on mine as witness.

Second, the base is made for a larger diameter scope. In reality this actually doesn’t make a huge difference and it still sits securely on the tube. I thought it might rock, but it doesn’t.

Overall it’s very well made and I’m pleased with it - does what I ask of it.

I was concerned about the previous review indicating that this wasn’t compatible with the WO redcat, but it certainly does fit my original version Redcat perfectly and can now attach my Astroessentials guide scope. Just don’t overtighten as that causes the base to bow inwards which then makes it too narrow for the guide scope shoe. Comfortably done up, no problem! Thanks to FLO for the buying advice and rapid delivery.

Well made adapter for William Optical telescopes. Do note however that it doesn't fit the Redcat51 or Spacecat51.

Bought this to mount a small guide scope on my William Optics Megrez 72 scope. Although the base has provision for two fixing bolts, there's only one attachment hole on the scope. Nevertheless this seems to hold the guide scope firmly and I've had no problems with any movement when guiding.

Purchased as a red dot finder mount for my Z61. It fits adequately but is obviously made for a larger diameter 'scope. It is secure though and will only ever support the RDF so is not likely to be stressed.
