Telescope with a 50mm objective lens, offering magnifications from 15x to 225x. I'm selling this because my child no longer uses it. The reason I've marked it as "slightly problematic" is that while most of the parts are present, something seems to be missing from the eyepiece section, preventing it from being securely fixed. I don't fully understand it myself, but it might still work as is, or perhaps it could be secured with tape. Please understand this before purchasing. - Model Name: GD-T003 - Magnification: 15x - 225x - Objective Lens Diameter: 50mm - Eyepiece Focal Length: 10mm, 20mm, 25mm - Tripod: Included - Uses: Astronomical observation, landscape viewing Thank you for looking.
