******************************* Please read the profile before purchasing. ******************************* Horizontal leveling bracket for Sky-Watcher Star Adventurer GTi. Made to look like the original. I think leveling the equatorial mount is a basic requirement for astrophotography. This equatorial mount has a level on the main body, but it's small... I was skeptical about whether it was properly leveled, so This bracket allows you to level with a larger level so you can be sure it's level. It's glow-in-the-dark so you can adjust it in the dark without a light. Once it's charged, it will glow dimly for several hours. You can check it without a light during shooting. It's not bright enough to disturb your shooting or the people around you. Please check the accuracy of the level to be attached in the 3rd photo. It is adjusted and checked to a level where a marble will not roll. Refer to photos 8-9 for installation. You can fix it by just tightening the screws, but I don't think you'll take it off once you've installed it, so If you're worried, you can use thin double-sided tape to adhere it. Try not to touch the level when fixing or adjusting the bracket. After adjustment, it is fixed with adhesive, but the accuracy may be affected if strong force is applied. Made with a 3D printer. This is a handmade product, so it is listed as "no noticeable scratches or stains". Please refrain from purchasing if you are sensitive. Equatorial mount, tripod, and other equipment are not included in the listing. I also use this product, so the design may be changed.
