A Short Tube Refractor Telescope is an optical telescope that uses a refracting lens to closely observe the night sky. It is one of the oldest and most commonly used types of telescope.
A Short Tube Refractor Telescope consists of a tube that has a lens at one end and an eyepiece at the other end. Light enters the telescope through the lens, which focuses the light to form an image. This image is then magnified by the eyepiece, allowing the observer to see the night sky in greater detail.
The most important factor to consider when choosing a Short Tube Refractor Telescope is the size of the lens, which determines the amount of light the telescope can gather. A larger lens will be able to gather more light, allowing for a brighter and clearer image. The size of the eyepiece also affects the amount of magnification the telescope can provide.
Setting up a Short Tube Refractor Telescope is relatively straightforward. The telescope should be placed on a stable surface, such as a tripod or table, and should be aligned with the North Star. Once aligned, the telescope should be pointed towards the desired object in the sky. It is important to ensure that the telescope is properly balanced to avoid any shaking or vibrations.
To ensure that the telescope is properly aligned and focused, the observer should use the focusing knob to adjust the focus of the lens. This will ensure that the image is clear and sharp. The observer should then use the tracking knob to adjust the telescope’s orientation so that the object stays in the field of view.
Finally, the observer should use the eyepiece to view the night sky. The eyepiece can be adjusted to provide different levels of magnification, allowing the observer to see objects in greater detail. The observer should be careful not to overexpose the image by looking through the eyepiece for too long.
With a bit of patience and practice, a Short Tube Refractor Telescope can be a great way to explore the night sky. With the right telescope, an observer can enjoy a bright and clear view of the stars and planets in the sky.
FOR BEGINNERS – Part 1/2. Review of the Orion Short Tube 80 Telescope
FOR BEGINNERS The price has actually come down quite a bit since its introduction in the 1990s. The newest version(s) sell for well under $200, and some of those even include a mount! Orion sold the optical tube (OTA) only for as little as $109. Early versions had a 6X30 finder and generic eyepieces. Later versions came with a much better 8X40 finder and better Expanse eyepieces, usually 20 mm and 6 mm, and sometimes they even threw in…
