Best Selling ItemsScope Cover £25.54 This Premium Woven Polyester Telescope Cover is specially treated to protect against snow, frost, rain, pollution and birds. What's more, it is ultra violet-stabilised to protect against the harmful effects of sunlight and its Weather-GardT protection means it is 100% waterproof. Integral ventilation flaps make it especially suitable for protecting a telescope. Solid brass eyelets and quality tie-cords are provided, and every cover comes complete with a durable zip-up storage bag. Use the cover to protect your telescope while you wait for the weather to change or when you don't want to take it in until the next day. Equally useful as a dust cover for indoor storage. The top picture shows it on an 8-inch Dobsonian but it is big enough to cover a 12-inch SCT such as an LX200. The bottom picture shows it protecting a C11 OTA mounted on an EQ6.

find out more | | CLS Visual Filter (1.25) £66.00 The Astronomik CLS is an inexpensive sollution for visual deep-sky observation, b&w photography and CCD observation. It is the right filter to improve the contrast of nearly all objects under light-polluted skies with all sizes of telescopes. Due to the design of the transmission curve the filter reduces the sky background. Gas nebulae, planetary nebulae as well as open clusters, globular clusters and galaxies are all seen better. The Astronomik CLS blocks the emission of Hg and Na streetlights as well as all Skyglow-lines . The filters are optimised for the use with focal ratios from f/4 ito f/15. Loss of transmission and colour distortion common with other filters are only evident with Astronomik filters at extreme focal ratios of f/2 and faster. Size: 1.25" find out more | | SkyLight Filter SCT Rear Cell £32.99 Protect the optics of your SCT from dust and improve the view. Celestron's Skylight filter threads onto the rear cell of C5, C6, C8, C9.25 and C11 telescopes, and onto the reducer plate of C11 and C14s. This general purpose, Wratten #1A filter improves color saturation and balance, increases visual and photographic contrast, helps to decrease glare in lunar and planetary observing, and penetrates atmospheric haze. find out more | | T Ring for Canon EOS | | 42mm OG Binoculars Lens Covers £9.00 Designed for 42mm objective binoculars; fits barrel diameters from 48mm ~ 52mm find out more | | Radial Guider  £108.99 Specifically for use in prime focus, deep-sky imaging or astrophotography with Schmidt-Cassegrain telescopes, the Radial Guider is compact and sleek in design. This accessory makes it possible to simultaneously photograph and guide through the optical tube assembly of your telescope. The Radial Guider also eliminates the problem of differential flexure, because you’re both guiding and photographing through the telescope. The Radial Guider is compatible with Celestron’s C5, C6, C8, C9¼, C11 and C14 telescopes and comes with a unique prism angle adjustment screw. It must be used with a guiding eyepiece, camera T-Ring and drive corrector (dual axis preferred). Primarily for use with catadioptric telescopes, but also works on refractor telescopes having adequate back focus. This guider is a tremendous improvement over conventional off-axis guiders. Not only is the angle of the prism tunable, but it also maintains a fixed rigid camera orientation while still offering users the freedom to move the guiding eyepiece radially about 135°. find out more | |
