Visual Astronomy Filters

Looking at the moon through a telescope can be like staring into a flashlight. This filter threads into your eyepiece and dims the view so you can see great detail and contrast on the surface...

The Celestron 1.25” Eyepiece and Filter Kit is a great way to expand the functionality and enjoyment of your telescope. Accessory Details Eyepieces All five Plossl eyepieces can be used in any telescope with a...

Our 1.25" Light Pollution Reduction (LPR) Filters are designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light. This includes mercury vapour, and both high and low pressure...

Colour filters enhance planetary imaging. Every refractive system, (lenses, correctors, eyepieces etc.) produce Chromatic Focal Shift: The different colours focus on different planes. By isolating one colour more detail will become apparent. Always use a...

When observing the moon or planets, a lot of the time there is just too much light! A-Star Telescope carries the Antares 13% and 25% (ND) neutral density polarizing filters to cut the brightness down...

When observing the moon or planets, a lot of the time there is just too much light! All-Star Telescope carries the Antares 13% neutral density (ND) polarizing filter for two inch eyepieces to cut the...

The distinction you'll find with Bandmate filters is their consistency, achieved by keeping control of the manufacturing and quality control processes each company does so well. All the materials are sourced in Germany. Each filter...
