Astronomik IR Pro (742nm) Filter

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.

Sensitivity of most CCD cameras is still fairly high in this region so smaller scopes (>5″) can benefit. Large telescopes (>10″) can benefit from the 807 filter, especially in poorer conditions.

    I use this filter for imaging the moon. I find it helps to steady the seeing which benefits focusing and the final image.
