Sky-watcher 2 Inch Light Pollution Filter
The Sky-Watcher 2 Inch Light Pollution Filter is a contrast-enhancing anodized 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 skies appear much darker, and the contrast between object and sky is improved significantly. This contrast-enhancement effect is particularly apparent on nebulae. Unlike stars, emission nebulae give off light in a very narrow range of wavelengths.

Sky-watcher 2 Inch Ultra High Contrast (uhc) Filter
The Sky-Watcher 2 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. Supplied with storage case.

Sky-watcher 2 Inch O-iii Narrowband Filter
The Sky-Watcher 2 Inch O-III 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.

Meade Dsi Ii – Deep Space Imager (colour)
The user-friendly astrophotography revolution continues. Introducing the new DSI II. It combines ease-of-use with a larger chip, greater sensitivity, higher resolution, and dramatically lower thermal noise. Meade engineers have invented a remarkable new way to reduce noise without a cooler. This means you can take exposures for hours at a time. And the new thermal monitoring sensors automatically match your dark frames to ambient temperature so it’s nearly impossible to take an uncalibrated picture. The software includes a new zoom feature for easier focusing and the squared pixels of the new larger chip make processing simpler and images more beautiful than ever. The DSI II is the world’s first un-cooled camera with low thermal noise. And that’s as cool as it gets.
