OPTIONAL ACCESSORIES

You will find that additional accessories for your PowerSeeker telescope will enhance your viewing pleasure and expand the usefulness of your telescope. This is just a short
listing of various accessories with a brief description. Visit the Celestron website or the Celestron Accessory Catalog for complete descriptions and all accessories available.

Sky Maps (# 93722) –

Celestron Sky Maps are the ideal teaching guide for learning the night sky. Even if you already know your way around the major constellations,

these maps can help you locate all kinds of fascinating objects.

Omni Plossl Eyepieces –

These eyepieces are economically priced and offer razor sharp views across the entire field. They are a 4-element lens

design and have the following focal lengths: 4mm, 6mm, 9mm, 12.5mm, 15mm, 20mm, 25mm, 32mm, and 40mm – all in 1.25” barrels.

Omni Barlow Lens (# 93326) –

It doubles the magnification of that eyepiece. A Barlow lens is a negative lens that increases the focal length of a

telescope. The 2x Omni is a 1.25” barrel, is under 3” (76mm) long, and weights only 4oz. (113gr.).

Moon Filter (# 94119-A) –

This is an economical 1.25” eyepiece filter for reducing the brightness of the moon and improving contrast, so greater

detail can be observed on the lunar surface.

UHC/LPR Filter 1.25” (# 94123) –

This filter is designed to enhance your views of deep sky astronomical objects when viewed from urban areas.

It selectively reduces the transmission of certain wavelengths of light, specifically those produced by artificial lights.

Flashlight, Night Vision (# 93588) –

The Celestron flashlight uses two red LED’s to preserve night vision better than red filters or

other devices. Brightness is adjustable. Operates on a single 9-volt included battery.

Collimation Tool (# 94183) –

Collimating your Newtonian telescope is easily accomplished with this handy accessory which

includes detailed instructions.

Collimation Eyepiece – 1.25” (# 94182) –

The collimation eyepiece is ideal for precise collimation of Newtonian telescopes.

Digital Camera Adapter – Universal (# 93626) –

A universal mounting platform that allows you to do afocal photography (photography through the

eyepiece of a telescope) with your digital camera.

T-Adapter – Universal 1.25” (# 93625) –

This adapter fits the 1.25” focuser of your telescope. It allows you to attach your 35mm (D)SLR camera for lunar and

planetary photography
