Astrodon Venus UV Filter round, 50 mm
Astrodon introduces a breakthrough in UV filters for astro imaging. A durable, hard-coated UV filter of the highest quality having the best transmission available.
Image the cloud structure of Venus and Jupiter with astro cameras on a telescope.
Use for general UV photography (flowers, insects, forensics).

The Astrodon-Schuler UV filter has traditionally been used for imaging Venus. It is made from several colored glasses, but only transmits ~ 65% of incoming UV light in the 300 - 400 nm region. Another vendor recently discontinued a 1.25" mounted UV filter due to NIR light leakage, but offers a 2" unmounted version that only reaches 80% T. Astrodon offers you both sizes and higher performance. Like the highest quality Generation2 Astrodon LRGB filters, the UVenus filter minimizes halos around bright stars.

Astrodon UVenus filters are guaranteed to achieve >90% transmission. The actual scan below has an average transmittance of 98.2% from 325 - 381 nm, while minimizing out-of-band light leakage. This outstanding performance saves you time when imaging weak UV signals, while providing high contrast due to low light-leakage. You do not need a separate filter to block the NIR with the UVenus filter.

WARNING!
This filter is NOT to be used for visual observations, specifically the sun or UV light sources!
