Ideal for near and deep-sky observation, Celestron's PowerSeeker 127EQ 127mm f/8 Reflector Telescope features a respectable focal length and a large, parabolic mirror that produce detailed images of the moon, clear views of the planets, and the ability to resolve bright distant objects such as nebulae and galaxies. The scope is outfitted with a 1.25" rack-and-pinion focuser and two eyepieces to get new users started, and a 3x Barlow lens that effectively triples the magnification of any eyepiece used with it to expand the usability.
The included manual equatorial mount features slow-motion control cables with large knobs to 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.
