More About the Astronomik H-Alpha 6 nm CCD Filter

An extremely narrow emission-line filter, the Astronomik 6 nm H-Alpha Filter is best equipped for CCD imaging with instruments as fast as f/3.5. It is not suitable for visual or solar applications. This filter allows h-alpha light from emission nebulae to pass through to your sensor while obstructing the remainder of the spectrum entirely.

The FWHM of the Astronomik 6 nm H-Alpha CCD Filter is optimized for maximum contrast between objects that emit H-Alpha, such as emission nebulae, and the background sky. While the 12 nm is similar in function, the 6 nm offers higher contrast gain due to the smaller FWHM. The trade-off is the dimming or eradication of some background stars in the final image. Using the Astronomik 6 nm H-Alpha in conjunction with the 12 nm H-Alpha filter will provide maximum contrast in HII objects (6 nm) while keeping background stars visible (12 nm) in the final image.

Given that the Astronomik 6 nm H-Alpha CCD Filter completely suppresses the main offenders of light pollution, mercury (Hg) and sodium (Na) emissions lines, it makes for an excellent filter for use in a light-polluted environment.

Astronomik EOS R/RP Clip Filter System

Astronomik EOS R XL clip filters are suitable for use with full frame mirrorless Canon EOS R and RP camera models. Facilitates imaging from both urban and rural areas, and does not require any modifications to the camera housing for use. Once the filter has been slid into place and is level, you can then reinstall the camera lens and you'll be ready to start imaging.

Without any tools and using only a finger, this filter can be easily installed. Removal does require the aid of an included small hook, but only initially. As soon as the filter is out far enough for you to grip with your fingers, you can go ahead and take it out the rest of the way and place it back in the case.
