90mm solar sheet 

• Reduce glare and increase contrast of the Moon with the Celestron 1.25” Moon Filter
• Also useful for extra bright planets as well as terrestrial viewing over sand or snow
• Threads onto most 1.25” eyepieces in seconds

Upgrade your lunar views with the SVBONY 1.25" Moon Filter. Designed to act as "sunglasses" for your telescope, it reduces intense glare and light pollution, revealing sharp details of craters and planetary surfaces. Built with premium optical glass and a durable metal frame.

IR 850nm Pass Filter is suitable for IR sensitive cameras.

• Darkens the background during twilight.
• Imaging of bright planets, stars, and comets by day.
• Imaging of young stars in dust clouds and stellar nurseries.
• Filter thickness: 11mm.

• Universal Light Suppression: Effectively reduces artificial lighting (mercury, sodium, and LED) while enhancing Hα, Hβ, OIII, and SII emission lines.
• Premium Optics: Features 2mm Schott® B270 optical glass with IBAD (Ion beam-assisted deposition) technology for superior durability.
• Nano Coating: Double-sided NANO anti-smudge coating provides excellent water and grease resistance.
• Pro Frame: Matte black anodized and Teflon-coated frame eliminates reflections and flares.
• Usage Tip: Recommended for SLR lenses with a focal length of 60mm or more to prevent color shift.
• Versatile Design: Specifically designed for Astro-Adapter M48-M56 P0.75mm telescope connections.

• Four great Moon filters in one kit—everything you’ll ever need for optimal views of the lunar surface
• Three neutral density (ND) filters with different levels of light transmission (13%, 25%, and 50%) allow you to choose the perfect filter for your viewing conditions
• Moon & Sky Glow filter provides high contrast views of the lunar surface and enhances observation of deep sky objects from light polluted skies
• Aluminum filter cells provide a rigid, durable housing for the filter glass and are threaded on top and bottom for stacking
• Kit includes a plastic carrying case with Moon map and legend for identifying the most popular lunar features

Astrodon SII5_36R Narrowband Filter for Astrophotography

Optolong L-Pro is multi-bandpass filter which offers better color balance by maximizing the transmission band. The balanced transmission allows astrophotos to be taken with minimal color cast to broadband emission objects such as galaxies, reflection nebulae and globular star clusters. L-Pro is the best choice for light pollution suppression.

• Isolates emissions of nebulae into H-Alpha and OIII
• Compatible with DSLR, color/monochrome CMOS, and CCD cameras
• Muli-layers of anti-reflection coating
• High density sponge carton lining

After years of R&D we have developed a new solar film that has the optical quality of glass with the advantages of impregnated polymer. Will never develop pinholes or scratches that can let in light and ruin a filter. Other advantages: lightweight and does not require re-balancing tube assembly, will not break, consistent yellow-orange solar image, even density with any aperture, flat surface compared to other thin film filters that have wrinkles and creases. Will not tear or puncture. Stronger than any other solar film on the market. Also available in sheets. Guaranteed 15 years.
