UHC filters are very useful aids in the fight against light pollution and natural sky brightness. They suppress artificial light but are transparent to wavelengths emitted by nebulous celestial objects. The effect of this for the observer and astrophotographer is considerably greater contrast.
The new Baader UHC-L filter is an all-purpose anti-light-pollution filter which also blocks LED lamp emissions in the blue part of the spectrum. Both passbands allow all of the light emitted by well-known nebulae through (the H-alpha and H-beta spectral lines of excited hydrogen as well as the OIII spectral lines of oxygen).
You can find all available filter sizes and formats here in our shop.
The Baader UHC-L filter offers all of the advantages of the CMOS-optimised Baader filter:
- Adapted for typical CMOS camera sensors
- Reflex Blocker™ coating
- Blackened edges
- Every filter is individually polished and coated for optical precision
- Life Coat™ coating for high durability
