Product Details

If you were to use only one filter with your SCT, a Skylight Filter/Dust Seal would be your most versatile choice. This general purpose, Wratten #1A filter improves color saturation and balance, increases visual and photographic contrast, helps to decrease glare in lunar and planetary observing, and penetrates atmospheric haze.

It's also an inexpensive way to protect your investment in quality optics as this filter serves as an effective dust seal. By leaving the Skylight Filter/Dust Seal on when removing or attaching other visual accessories, you prevent dust and other atmospheric contaminants from entering the rear of your telescope. Needless to say, it's much easier to clean a dusty filter than a dusty primary mirror, secondary mirror and corrector plate.

The Skylight Filter/Dust Seal must be threaded onto the rear cell of instrument before any other accessory is installed. The female end attaches to the rear cell of your telescope. All additional accessories then mount onto the exterior/male threads of this filter. This filter has a standard SCT female thread (2"x24tpi) on one side to attach to the male SCT thread on the rear cell of your Celestron or Meade telescope.

Made by GSO of Taiwan, this is the same product that is sold under the brand name of another major telescope manufacturer for a lot more. Clear aperture = 34.4mm (1.35"); Weight = 2.1oz.; Maximum Diameter = 56.9mm (2.24"); Length = 23.5mm (0.92").
