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 SkyTech CLS Canon EOS Clip Filter aids astrophotography on Canon APS-C EOS cameras by blocking light pollution while allowing light from deepsky objects through. The CLS filter has a wide pass-band, giving a natural colour rendition, meaning it is ideal for areas with moderate light pollution such as in city outskirts or suburban locations.
Cheshire Collimating Eyepiece.Designed to assist with the accurate collimation of a Newtonian reflector telescope.
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.
This 1mW red laser collimating device boasts some of the best and most practical functions collimators can offer. A large display window allows the user to clearly see the face of the device. Whilst most other brand name collimators only have one setting, this has seven adjustable brightness levels. The 1.25" laser collimator comes complete with a removable
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
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
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.
The mirrors inside these diagonals have undergone a special high-reflectivity multi-coating process, allowing them to reflect 99% of the precious gathered starlight, providing exceptional brightness and contrast (Standard diagonals typically reflect 90-95% of light).
The SkyTech CLS-CCD Canon EOS Clip Filter aids astrophotography on Canon APS-C EOS cameras by blocking light pollution while allowing light from deepsky objects through. The CLS-CCD filter has a wide pass-band, giving a natural colour rendition, meaning it is ideal for areas with moderate light pollution such as in suburban locations.
