What is the cstar t45375 worth ? - The Optics

The Cstar Optics Cstar BW-750B 7x-50mm Waterproof Binocular does not require any batteries for normal operation. It is a purely optical instrument that uses lenses and prisms to magnify the image. However, some binoculars may have a built- in digital compass or range finder that requires batteries. If your specific model has these features and requires batteries, you can typically find the battery compartment on the side or bottom of the binocular. The required battery type and number will be specified in the user manual or on the binocular itself. If you are having trouble finding or replacing the batteries, I would recommend reaching out to the manufacturer or a trusted optics specialist for assistance.

Maybe it has slipped down the side of the sofa - things often do. If you wish to obtain a replacement, Google the make and model followed by the word manual.

Both axis can be unlocked by loosening the knobs holding each axis.

Inner scope??? you mean the eyepiece (s) are broken. Measure the hole eyepieces come in 3 sizes, .965, 1.25, and 2 inch sizes.

The .965 eyepieces are very difficult to find as most amateur telescopes use the 1.25 inch size.

Try Telescope Warehouse or Agena Astroproducts for a replacement eyepiece:

Don't ever buy another off brand telescope at a garage sale that you know nothing about.

You will not find a manual. BUT you do not need one.

This is a very simple reflector telescope on an Alt Az mount. Easy to move uop or down and left and right.

The eyepieces simply go into the focuser. The Larger the number written on the eyepiece the LESS the magnification.

Take the scope outside during the daytime and practice focusing on a distant object using the eyepiece with the largest number.

The manual WILL NOT tell you how to find those small dim objects in the sky. It's just assembly instructions.It does not tell you how to become an amateur astronomer.

Locate a local Astronomy club and seek advice from the members, who will be glad to help you with your telescope.

This is considered a toy telescope. You will not find a manual or replacement parts.

You won't find a manual for those small telescopes. However Meade maintains a site with their manuals. Find one similar to your scope under REFLECTORS and download the manual.
