DSLR Astro Conversion Filter for Canon EOS 7-40-50-400-450-500-550-600-1000-1100D
Baader have made an IR cut filter that replaces the standard internal Canon filter. This filter has high transmission of the H-Alpha line and eliminates the cameras’ major disadvantage for astro-imaging.
-
The Astronomik CLS Filter (not IR blocked) is the best deep sky and general purpose filter and one of my favourites.
This broadband light pollution filter works on all objects for both visual use, and imaging with standard and Baader modded DSLR cameras.
Blocks Sodium, Mercury and air-glow emission.
Can also be used as an effective minus violet filter by refractor owners.
Not UV / IR blocked.
-
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.
Comparison between Baader UV/IR cut and Astronomik IR Pro 742 filters
-
The Baader UV IR Block L Filter is excellent at blocking UV and IR, passband is 420nm – 680nm.
-

-
The Astronomik CLS CCD Filter IR Blocked has all the benefits of the standard CLS CCD filter but with IR blocking built in.
