Canon DSLR Astronomik IR Pro (742nm) Filter
Rated 5.00 out of 5
£44.00 – £89.00

Add to Wishlist

The IR Pro (742nm) Filter pushes the passband of the Baader and Altair IR pass filters further into the Infra Red. At these longer wavelengths, planetary images are much less disturbed by distortions in the atmosphere.

This is the best “Planet Killer” filter, based on research by Astronomik to determine the optimal passband for enhanced Planetary Imaging, with most amateur equipment.

Sensitivity of most CCD cameras is still fairly high in this region so smaller scopes (>5″) can benefit.

Due to the combination of low half-width and high transmission of almost 100% in the area of the OIII line, the filter delivers a maximum signal in the desired wavelength, but blocks all other radiation and thus ensures an extremely dark sky background.
