Optical Tube Telescope Function. Optical tube assemblies are sold without mounts and can be adapted to a wide variety of mount types. Items 1-24 of 384. Page. You're currently reading page 1; Page 2; Page 3;. Optical tubes or optical tube assemblies (OTA) are standalone tubes that do not come with their own mounts or tripods. Optical tubes are usually bought to complement an.
An optical tube telescope is a type of telescope that typically features a long, thin tube with a light-gathering lens at the top and an eyepiece at the bottom. It works by capturing light from celestial objects, such as stars and planets, and magnifying them to allow for clearer observation and analysis. Optical tube telescopes are often used for amateur astronomy, and they can be quite affordable compared to other types of telescopes.

How Does an Optical Tube Telescope Work?
An optical tube telescope uses lenses and mirrors to gather and focus light from distant objects in outer space. The telescope’s primary lens, or objective lens, is located at the top of the telescope tube and is used to gather light. This light is then reflected off of a secondary mirror, which is located in the center of the tube. This secondary mirror directs the light towards the eyepiece, which is located at the bottom of the tube. The eyepiece is used to magnify the light, allowing the observer to make out details from the images.
The size of the primary lens and secondary mirror are important factors in determining the resolution and clarity of the image. A large primary lens and secondary mirror will allow for more light to be gathered and focused, resulting in a clearer, sharper image. Additionally, the eyepiece can be swapped out for various magnifications, allowing for more detailed observation.
Optical tube telescopes also typically feature a mount, which is used to point the telescope towards the desired object. The mount features a motor that can be used to track objects in the night sky, allowing the user to more easily focus on the desired object. Additionally, the mount can be used to rotate the telescope tube, allowing the user to observe objects at different angles.
Optical tube telescopes are a great choice for amateur astronomers, as they can be quite affordable compared to other types of telescopes. Additionally, they are relatively easy to use and maintain, making them an ideal choice for beginners. With a bit of practice, an optical tube telescope can be used to observe and study a wide range of celestial objects.
The Basics of Telescope Eyepieces
A basic overview of eyepieces for beginner telescopes. I cover the eyepieces that come with many beginner telescopes, details on the different types of eyepieces, and general ideas about upgrading and buying new eyepieces. Some of the eyepieces I discuss in this video: Orion Sirius Plossls amzn.to/2LgZzhM Celestron XCEL LX amzn.to/2L9tYOZ Orion Stratus amzn.to/2rZTNZZ Badder Hyperion amzn.to/2Lc3CvA Televue Naglers amzn.to/2GxZhPO
