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,
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
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.
Cheshire Collimating Eyepiece.Designed to assist with the accurate collimation of a Newtonian reflector telescope.
The Skywatcher 2 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,
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
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 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
The Sky-Watcher 1.25 Inch Ultra High Contrast (UHC) Filter is the best all-around dark-sky nebula filter. This filter permits superb views of objects like the Orion, Lagoon, Swan and other extended nebulae. It performs well in smaller aperture instruments owing to its greater light transmission than the O-III, yet still suppresses light pollution well.
Designed for serious Astro-Imagersand optimised for the Evostar-80ED PRO, the Sky-Watcher 0.85x Focal Reducer/Corrector effectively reduces the telescope's focal length by a factor of 0.85x and provides much improved field-edge correction. Use in conjunction with Sky-watcher's M48 Canon or Nikon T-ring adaptors (product codes 20237 & 20238).
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).
