8 Inch Telescope Tube Rings.
Telescope tube rings are an essential component of all telescopes. They are used to securely mount the telescope tube to the mount. 8 inch telescope tube rings are most commonly used for amateur telescopes with apertures of 8 inches or less, such as the Celestron 8-inch telescope.
The telescope tube rings consist of two semi-circular rings that are connected by two or more adjustable mounting screws. The rings are usually made from aluminum or stainless steel and are designed to be light yet strong enough to support the weight of the telescope tube. The mounting screws are used to adjust the distance between the rings, which is necessary to ensure that the tube is centered in the mount.
When mounting an 8 inch telescope tube in the rings, it is important to make sure that the tube is centered in the mount. To do this, you should first place the tube in the rings and loosely tighten the mounting screws. Then, use a spirit level to check that the tube is level in the mount. If the tube is not level, adjust the mounting screws until it is. Once the tube is level in the mount, tighten the mounting screws to secure the tube.
It is also important to make sure that the tube is not too tight in the rings. If the tube is too tight, it may cause the rings to bend or even break. To ensure that the tube is not too tight, you should be able to move the tube from side to side and up and down in the rings. If the tube is too tight, you should adjust the mounting screws until it can move freely.
When installing the 8 inch telescope tube rings on a mount, it is important to make sure that the mounting screws are properly aligned with the mount. The screws should be placed in the same plane as the mount and should be evenly spaced. Once the screws are in place, use a wrench to tighten them securely.
It is also important to check the rings for any signs of wear or damage before using them. If any of the rings show signs of wear, they should be replaced. Properly maintained telescope tube rings should last for many years.
Don't Buy Telescope Tube Rings: Make It Yourself
Classic vintage refractor, or telescopes like ETX need tube rings if you want to use them without their original mounts. Here I have discovered a new way to use a cheap substitute for the tube rings that can attach any small to medium telescopes to a Vixen dovetail. This way you can use them on any modern mount like SkyTee-2 Alt Azimuth mount or GEMs and even do guided astrophotography! I use cable ties. In making this video I have used these…
