Telescope-Accessories-Askar C1 ColourMagic 2″ Duo-band Filter – Ha and OIII

Check Out This Ha / OIII Duo-Band Filter From Askar!

Adding this Askar Colour Magic C1 filter to your color camera effectively blocks light pollution while providing incredible detail in the Ha and OIII wavelengths! Ideal for city astronomers, image beautiful emission nebula in high contrast and stunning clarity.

By adding narrowband imaging capabilities to color camera users, isolate intricacies of nebulae in one shot! There is no need to purchase additional filters for different wavelengths, as you can collect rich signal with just this Colour Magic C1 filter. A band pass of 15nm±3nm in Ha and 35nm±5nm in OIII separate the background sky from the nebulosity within the frame for sharp, clear images. Understanding the limitations OSC camera users face, Askar introduces a unique method of creating the popular SHO Palette, something formerly only available with monochrome cameras!

SHO Palette for Color Camera Users!

While this C1 filter is incredible by itself, it truly shines when paired with the Askar Colour Magic C2 Filter (not included). This C2 filter isolates wavelengths in OIII and SII, and when this data is merged with that of the C1 filter, color camera users are able to create a full SHO color palette within their images! This ability was previously only available for monochrome camera users with the requirement of three different filters. Thanks to the innovation from Askar, Hubble Palette color mapping can be achieved by anyone! Check out the bundle of both of these filters here: ColourMagic C 2″ Duo-band Filter Package.

Elevate Your Deep Space Imaging

This Askar Colour Magic filter offers highly detailed, colorful narrowband images for OSC camera users! Whether it be through light pollution suppression, compatibility with numerous set ups, or quality craftsmanship, see why this dual narrowband filter is a must have amongst your astronomy gear.

Emission Nebula Imaging
Emission nebulae are celestial bodies that emit certain wavelength of light, typically in the Ha, SII, and OIII band passes. This Askar Colour Magic C1 filter has a peak transmittance of 90% in the 500.7nm (OIII) and 656.6nm (Ha). By separating these wavelengths, intricate details can be discerned from the light polluted background sky. In post processing, mapping these captured wavelengths to certain color channels develops unique and creative images of these deep space objects!

Extensive Compatibility
Compatible with most filter wheels and filter drawers, seamlessly join this Askar Colour Magic C1 filter to almost any set up! The wide surface area can easily cover full frame sensors, bringing narrowband imaging to a wide variety of color cameras.

Premier Construction
This Askar Colour Magic C1 features a thickness of 2 ± 0.05mm and was crafted with quality in mind. A surface finish of 60/40 and barrier property of OD3 at 200-1000nm delivers high performance transmission for crystal clear images!
