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.
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.
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 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,
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
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.
This long-pass filter limits transmission of light with wavelengths longer than 650nm. Whilst suppressing all other polluting lights, the filter allows you to observe emission nebulae with greatly enhanced contrast. Ideal for observing emission nebulae or objects that emit in the H-alpha region. Suitable only for CCD photography. Threaded to fit standard
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.
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 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).
