Celestron Observer’s Accessory Kit – 1.25” Eyepieces, Filters, and Barlow Lens

A Versatile Expansion Kit for Visual Astronomy

The Celestron Observer’s Accessory Kit is an excellent upgrade for any amateur astronomer looking to expand the capabilities of their telescope. Whether you're observing the Moon, planets, or taking your first steps into basic astrophotography, this thoughtfully curated set provides essential accessories to improve your viewing experience.

Housed in a compact, foam-lined plastic carry case, this kit includes high-quality eyepieces, useful filters, a versatile Barlow lens, and a cleaning cloth—all designed to fit any telescope with a 1.25” focuser.

Eyepieces

17mm and 6mm Plössl Eyepieces (1.25”)
Both eyepieces feature a classic four-element Plössl optical design with a 52° apparent field of view.

• The 17mm eyepiece offers a medium magnification, ideal for wide-field lunar viewing or larger deep-sky objects.

• The 6mm eyepiece provides higher magnification, well suited to planetary details and tight lunar craters when atmospheric conditions allow.
  Each eyepiece is fully multi-coated for optimal light transmission and contrast.

2x Barlow Lens with Integrated T-Adapter

This dual-purpose Barlow lens doubles the magnification of any 1.25” eyepiece, extending the utility of the two included eyepieces and any others in your collection.

• Converts the 17mm to an 8.5mm and the 6mm to a powerful 3mm for very high magnification.

• Integrated T-threads allow for basic DSLR astrophotography by attaching an optional T-ring to your camera.
  Instructions for camera attachment are included in the kit.

Colour and Moon Filters

Three threaded filters enhance contrast and control brightness for planetary and lunar viewing.

• #80A Blue Filter: Increases contrast of Jupiter’s cloud bands and Saturn’s poles. Also useful on the Moon for a sharper visual edge.

• #25 Red Filter: Ideal for Mars, highlighting polar ice caps and surface features. Best used with larger aperture telescopes.

• Neutral Density Moon Filter: Reduces the Moon’s brightness for comfortable observation and improved detail. Also effective for viewing bright planets like Venus.

Cleaning Cloth and Carry Case

A high-quality microfiber cloth is included for safe removal of fingerprints or dust from your lenses and filters. The compact plastic case features custom-cut foam to hold each component securely in place and protect your accessories during storage and travel.

This convenient, all-in-one kit is perfect for new telescope users and experienced observers alike. It adds optical variety, improves contrast, and increases magnification options—all while keeping your gear organised and protected.
