Eyepiece Accessories and Filters
Celestron's Moon Filter is an economical eyepiece filter for reducing the brightness of the moon and improving contrast, so greater detail can be observed on the lunar surface. The clear aperture is 21mm and the transmission is about 18%. Screws on to the filter thread of any Celestron, or other manufacturer's 1.25 inch eyepiece.
The Sky-Watcher 1.25 Inch Light Pollution Filter is a contrast-enhancing anodised aluminium, optical glass filter designed to block out the wavelengths of light emitted by mercury-vapour light and other common causes of light pollution, whilst providing higher transmission at critical hydrogen-alpha and hydrogen-beta lines than competing filters. Bright,
The Baader Hyperion Eyepiece T-Adapter enables you to attach cameras fitted with T-rings to Baader Hyperion eyepieces for eyepiece projection photography. It is suitable for use with Baader eyepieces with a 43mm thread - such as Hyperion fixed focal length eyepieces and the Mk III 8-24mm zoom eyepiece (but not the Mk II zoom eyepiece) - attaching to the
The Sky-Watcher 1.25 Inch O-III Narrowband Filter narrowband filter is specially designed for the observation of gas and planetary nebulae. It distinguishes different contrasts of the wavelengths of light that pass through, giving ideal conditions for the observation of faint super nova remnants and planetary remnants.
The Baader contrast filter booster will help sharpen up your stellar images, boosting contrast, emphasising lunar, Martian and Jovian surface details and cutting down on visible light pollution. The filter is especially useful in economy refractor telescopes, where it can aid in the correction of colour aberration.
The Sky-Watcher 2 Inch Light Pollution Filter is a contrast-enhancing anodised aluminium, optical glass filter designed to block out the wavelengths of light emitted by mercury-vapour light and other common causes of light pollution, whilst providing higher transmission at critical hydrogen-alpha and hydrogen-beta lines than competing filters. Bright, light-polluted
Baader Solar Filters provide a professional and secure solution to observe and image the Sun using AstroSolar Safety Film. Many ready-made filters stretch the filter material like a drumhead in order to make it look like a piece of glass – this absolutely destroys the image quality, rendering the film useless for high magnification work. AstroSolar film
This Sky-Watcher Coma Corrector is optimised for all Sky-Watcher fast-ratio f/5 Newtonian Reflectors / Dobsonians, with 2” focuser. Delivers stunning wide-field views with pinpoint stars to the edge of the field. Magnification remains unaltered. Supplied complete with necessary adaptors for visual use. For imaging use with a DSLR camera, a suitable M48x0.75
This handy, time-saving device is a must-have for astronomers, for both visual and photographic use. Up to five filters can be installed in the threaded, numbered compartments, and each can be selected for your eyepiece or camera by simply rotating the inner wheel to any of the five click-stop positions. One compartment can be left empty for unfiltered
The Baader Neodymium + IR Cut-Off (Moon + Skyglow) filter drastically improves contrast for all reflector telescopes, without loss of brightness. The filter greatly intensifies surface details on Mars, Jupiter and Moon and enhances many deep sky galaxies and nebulae against the background sky. The Neodymium element greatly reduces glare and unwanted street
The 1.25" Baader 6 Colour Filter Set comprises three longpass and three genuine bandpass filters, which act similar to a nebula filter, so that only a small portion of the visual spectrum is transmitted to emphasise certain planetary surface detail. All filters have standard 31.7mm eyepiece filter threads. The set consists of the following colours: dark
