More About the Astronomik H-Alpha 12 nm CCD EOS R APS-C Clip Filter

For deep sky astrophotography with Canon EOS R APS-C camera models under light-polluted skies, the Astronomik H-Alpha 12 nm CCD EOS R XL Clip Filter is ideal. Its 12 nm FWHM is optimal for Canon cameras, enabling the use of very fast optics. F/number application range spans from 1:2.8 to 1:15. Transmission losses and chromatic distortions, something that can be a nuisance with other filters, only happen when super bright aperture ratios of 1:2 and more are used. Using this filter guarantees 90% transmission or more at H-Alpha (656nm). This filter is made to Astronomik's exacting standards. While transmission ratings may vary between each filter, you are guaranteed a transmission rating greater than 90%, with a typical transmission rating of around 96% for the 12 nm Ha. The specific T-Max will be listed on the filter case. You can rest easy knowing that every unit is thoroughly tested and guaranteed to meet Astronomik's stellar benchmark of performance! Another asset of this 12 nm filter is the easy availability of guide stars for cameras with an incorporated autoguider.

Astronomik's H-Alpha 12 nm Filter enhances the contrast between objects, in this case between targeted objects with H-Alpha emission lines and the skyglow background. This filter also provides total suppression of emission lines from artificial sources such as mercury and sodium-vapor from street lamps, making it an excellent light pollution filter! Because of the high optical quality of the Astronomik H-Alpha 12 nm substrate, you won't be able to tell the difference between the razor-sharp stars seen with a camera or with your regular telescope.

Like all Astronomik filters, H-Alpha 12 nm CCD filters are parfocal with all other Astronomik filters, and are delivered in a high-quality, long-lasting plastic storage case. This filter completely blocks out all unwanted wavelengths in the visible and IR parts of the spectrum. Diffraction-limited, your telescope's optical performance will not be compromised. Furthermore, this filter features a very thin substrate and is highly resistant to the effects of scratching, aging, and high humidity.

Astronomik EOS R Clip Filter System

Designed for Canon EOS R APS-C cameras for use in both metropolitan and suburban viewing areas, Astronomik EOS R APS-C clip filters do not require any camera modifications to be used.

Installation may be performed without tools using only one finger, while a small hook is included for initial help with filter removal. As soon as the filter is out far enough to grasp, you can use your fingers to take it out and place it back in its case. Imaging can begin once this filter is rested flush into place and the camera lens has been reinstalled.
