Eyepiece Accessories and Filters
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,
90 degree Erecting Prism designed to fit 1.25/31.7mm focusers and eyepieces.Designed to give a more comfortable viewing position, and to correct upside down images.
Whether you're looking to build a telescope system from scratch, or wish to upgrade your "kit" Star Diagonal, the Altair Astro 2 inch Quartz Dielectric Diagonal offers 99% reflectivity due to its multi-layer dielectric coatings, and extreme durability thanks to its CNC machined aluminium casing. It has a non-marring brass compression ring to prevent damage
Perfect for both astonomical and terrestrial observing, these fully-coated diagonals offer correctly oriented images with excellent sharpness and contrasts. Designed for 1.25 Inch/31.7mm focusers and eyepieces.
The Skywatcher 1.25 Inch Variable Polarising Filter is a high quality anodised aluminium, optical glass variable polarising filter designed to reduce the amount of light entering your eyepiece. You can progressively dim the view when observing a bright object, such as the Moon or certain planets, to a level according to your needs, whilst increasing contrast,
The Altair Astro Premium Neutral Density Moon filter blocks 25% of the light passing through it removing excess glare from lunar images helping to bring out finer detail. Threaded to fit 1.25 inch eyepiece barrels.
Enhance your viewing of the planets and the moon. Even a 3/4 moon can reflect enough light to strain the eyes, so the use of a moon filter helps to reduce the incoming light and will even improve the contrast. The coloured filters are matched to help improve the viewing of a number of the Planets, and even comets.
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 Lightwave 1.0x Field Flattener is a non-focal reducing field flattener which gives improved results for photography with triplet and doublet refractor telescopes of between f5.5 and f6.5 focal ratio. The Field Flattener comes with a CNC machined T-threaded end-cap to protect against dust on the rear lens element which is more exposed than the front
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
Experience unrivalled views of our nearest star with one of these fantastic solar filters. These fully-mounted filters are far safer and easier to use than 'solar film' as they are mounted in a frame which is securely attached over the end of your telescope or camera lens via thumb-screws. This not only means that the filter can be quickly and easily attached
