Premium Grade H-alpha 35nm CCD Filter 2" (optically polished) from Baader Planetarium

Baader's new H-alpha CCD passfilter with medium 35nm-wide FWHM bandwidth is ideal for use with interline CCD cameras (although cannot be used on its own for protuberance imaging).

It's an excellent high-contrast deep sky red filter for RGB use, optimised for all interline CCD chips. It allows CCD-contrast images of H II regions (e.g. North America Nebula) and images can be taken even from "light-polluted" areas.

It comes with a non-aging efficient hard coating on a planeoptically polished surface. Ideal for fast optical systems between f/10 and f/2.8.

It will cause NO haloes and NO reflections. According to the spectral analyse (please see the image below) IR is blocked as well.
