Telescopes & Astronomy

• Instantly transform your normal Celestron 6” Schmidt-Cassegrain telescopes(6" SCT) into a yellow-light solar telescope (complete list of 6" SCT look in description section)
• ISO compliant solar safe film protects your eyes when viewing the sun, unlike some other filters on the market
• Solar film produced in the USA by American Paper Optics, one of the suppliers recommended by NASA for safe solar viewing
• Designed from the telescope’s lens cap for a snug fit, each filter includes two safety Velcro straps and four self-adhesive Velcro pads for safely securing your solar filter in place

These are safe full aperture (sometimes referred as clear aperture) solar filters. This means that it allows the most light possible into the telescope because it allows the full aperture of your telescope to be viewed. The full aperture allows the best possible daytime viewing when there is minimal atmospheric turbulence.

Adding the ZWO O-III Narrowband filter to your imaging collection will help you go beyond RGB imaging and capture your favorite nebulae in a totally new light, no matter how polluted your skies may be!

• Fits Optical Tube Diameter 7 1/8" (181mm) to 7 3/8" (187mm)
• Safe for viewing the Sun
• Blocks 99.999% of incoming light
• Compatibility: LX70 R6, LX65 6" MAK & 6" ACF™, LX85 6" MAK, ACF™ & 6" Reflector

The ZWO narrowband O-III 7nm filter is designed for nebula observation allowing 7nm bandwidth of light centered on a wavelength of 500nm through,  which corresponds to OIII emission lines, blocking out all other light.  Adding the ZWO O-III Narrowband filter to your imaging collection will help you go beyond the RGB imaging and will help capture your favorite nebulas in a totally new light, no matter how polluted your skies may be!

If you'd like to enhance your astronomy experience with some colour planetary filters, why not go for the saxon 2" Colour Planetary Filter Set?

This set comes with four filters of yellow, red, dark green and blue.

Astrodon 5nm Narrowband Filters – H-alpha 5nm

H-α (hydrogen-alpha) at 656 nm (nanometers) is deep red in color and the most popular narrowband filter. Hydrogen is ubiquitous in the cosmos and is present in emission nebula (North American, Pelican), planetary nebula (Dumbbell, Ring), Wolf-Rayet objects (Crescent, Thor’s Helmet) and supernova remnants (Veil).
