I discovered there is an additional M5 threaded hole under the manufactures sticker on the Skywatcher ESPRIT 100ED.
By installing this shoe I am better able to distribute the weight of my ZWO EAF, guidescope and ASIAIR Pro to achieve good side to side balance on the mount.
The quality of the shoe exceeds that of the shoe supplied with the telescope.

Solid bit of equipment. Excellent quality.

Bought this to fit the skywatcher finder scope onto my old Celestron 8 inch SCT. Screws onto the celestron snugly (using the screws already on the celestron). Also the fit for the finderscope dovetail is good and snug. Happy with it.

This is a well-made and solid-feeling shoe which firmly secured the finder to the OTA. To fit it to my Heritage 130p, I removed the primary mirror and covered the secondary with a plastic bag to prevent dust/scatching. I marked up the outside of the tube with a pencil and drilled three 5mm holes with a HSS bit, directly vacuuming away the metal debris. I then used three 8mm M5 black countersunk socket screws and nuts (not supplied with the shoe) to attach the shoe. These screws are short enough that they don't protrude into the mirror's working aperture.

I bought a Sky-Watcher 9x50mm RACI finder at the same time, which sits firmly in the shoe with the screws done up exactly as it should!

The only thing that would make this shoe better is if bolts/nuts were supplied with it.

Super fast speedy delivery and very well packed.
A quality adaptor.

As ever excellent service. Great price and incredibly good delivery.

I bought this because I wasn't happy with the cast item my scope came with. This clamp has precise machined dovetail and very well made finish. The shoe of my finder scope fits perfectly. A nice upgrade for your scope! I am much more confident in my guide camera tracking well now. Excellent

Superb quality, a great price avd next day delivery. A1 service!
