A 4 inch telescope tube is an essential piece of equipment for any amateur astronomer. It is the main part of the telescope, and it houses the optical components. The tube is usually made of metal or plastic and is typically rectangular in shape. It can be either open-ended or closed-ended and generally ranges in length from about 10 to 20 inches.
The most important part of the telescope tube is the objective lens, which is the main lens that collects light and images. In a 4 inch telescope tube, this lens is usually made of glass and has a diameter of 4 inches. The other components of the telescope tube are the eyepiece, which is used to view the images, the focuser, which is used to adjust the focus, and the finder scope, which is used to help locate objects in the sky.
When purchasing a 4 inch telescope tube, it is important to make sure that the components are compatible with each other. For example, the objective lens should be the same size as the eyepiece and the focuser should be able to adjust the focus of the lens. Additionally, the tube should be made from a high-quality material that is resistant to wear and tear.
Setting up a 4 inch telescope tube can be a bit complicated, but it is not too difficult for a beginner. Generally, the tube should be attached to a mount or tripod and the objective lens should be positioned at the opening of the tube. The eyepiece is then inserted into the focuser and the focuser is adjusted until the image is in focus. Finally, the finder scope is used to help locate objects in the sky.
Cleaning the 4 inch telescope tube is an important part of keeping the telescope in good condition. Generally, the tube should be wiped down with a clean cloth and any dust should be removed. Additionally, any fingerprints or smudges should be removed with a soft cloth.
Using a 4 inch telescope tube is a great way to explore the night sky. With a little bit of practice and patience, anyone can become an amateur astronomer and view galaxies, stars, planets, and much more.

Could it be the smallest 4" telescope in the world? I build this little Dobsonian as a scale model of my 16" f/4 Propdob.
