> 3 dayWill fit the Explore Scientific ED80 if you replace the stock screws with 6mm m5 screws. Itll overhang on both sides but a small strip of electric tape to keep it from scratching is all you need.

> 3 dayPerfect finder shoe for 8 SCT scope. I used this on my Celestron CPC800 and found that the elongated mounting holes were just shy by about 1-2 mm to match up with the scope. The shoe is made of relatively soft metal and I simply used a round file to extend one hole slightly. The two set screws ensure that the guidescope Ill use is firmly in place and wont move during set up and tear down. I looked long and hard for a suitable shoe and this one is it, albeit with a minor effort on my part. I suspect it fits perfectly on other 8 scopes. Im quite happy with my selection.

11-06-2025I use this with my Celestron C6 for mounting the ASIAIR PRO. The natural curve matches my C6 perfectly. Quick install, lightweight and quality materials have made this quick release my top pick!!

> 3 dayReplaced the original red dot finder base with this one as I could not get the original celestron provided out of box red dot finder to align to the 5SE telescope. This product works well with the Nexstar with no additional holes required to be drilled. I also replaced the original celestron provided red dot finder with a finderscope with cross hairs. The combination solved my problem of lack of alignment. Recommend product.

> 3 dayI purchased this for a 1990s Celestron C8 SCT. Fit perfect, the mounting allows the screws to be at an angle so they thread in and do not interfere with the guide scope dove tail as my other did. Nicely made and holds scope nice and tight with the dual screws.

Greater than one weekI bought this as part of a mounting rig for a guide scope for a star tracker. This particular part is of high quality and works well.

Precision machined finder shoe base in matte black, made of high strength aluminum with anodizing aluminium process, durable for long time use. The aluminum material makes the product lighter and easier to carry. |
The base forms two linear constraints on each tube radius of 130-400 mm in diameter, which gives maximum stability. The base also carries small guidance/CCD guider without any problem. |
Two large knurled thumbscrews makes it easy to install: Bases feature two large thumbscrew locks to secure your finder scope or reflex sight in place, even while wearing gloves. Just put it on the optical tube and tighten the screws. |
There are two elongated holes on this base and a single countersunk hole for screws up to M5 in the middle. Two screws are on the side of base. The distance between the center points of the screw holes is 24 to 41 mm. |
