Product description

With a peak width at half height of 7nm, these filters are excellent for use with full-frame CCD cameras.

These filters are of course perfectly anti-reflective and plane-optical polished!

It is a high-contrast red deep sky filter for RGB use. The filters are optimized for all full- frame CCD chips. Superb high-contrast CCD images of H-II regions are even possible in 'light-polluted' locations (e.g. of the North America Nebula).

They are not suitable for home-made prominence set-ups.
