Spectral transmission — Baader Venus I Ultraviolet-pass

At first glance, the original “Venus I” filter doesn’t seem much different than the Venus II filter. Yet field reports from ultraviolet shooters indicate that the infrared-blocking performance of the Venus II is much improved.

Notice the “bump” near 780nm on the Venus I which is not present on the Venus II; this is the source of the infrared contamination that is so disliked— there is often many times more infrared present than ultraviolet, so even a small leak can overwhem the UV image.
