Designed for near and deep-sky observation with a fast focal ratio for astrophotography/imaging, Celestron's AstroMaster 130EQ 130mm f/5 Reflector Telescope features a 650mm focal length and a spherical mirror.
The scope is outfitted with a 1.25 rack-and-pinion focuser and two eyepieces to get new users started: a 10mm that yields 65x power and a 20mm for a 32.5x magnification. The 20mm eyepiece integrates an erecting system to correct images horizontally and vertically to allow easy terrestrial use. An unmagnified red-dot finder is also included to help set-up, align and navigate easier.
The included manual equatorial mount features slow-motion control cables make it easy to track objects even when wearing gloves, while also minimizing vibrations caused by handling the mount with your hands; and clearly visible indicators on the Right Ascension and Declination axes. An adjustable-height aluminum tripod rounds out the rig with a tray for accessories such as eyepieces, filters, and lights.

Permanent and irreversible eye damage may result.
- Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
- Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present
