I just reread my post, should be a glass filter that transmits in UV but blocks IR!

Quoting jimchung2338 <jim_chung@sunshine.net>:

Seeing was predicted to be good to very good on Friday night, Feb 06,

and I captured Venus just as the Sun was setting through an old Baader

UV filter and a glass filter that transmits UV but blocks UV.  This is

because the previous generation of Baader Venus/UV filters suffered

from IR leakage and Milton brought my attention to this fact last year.

No discernable cloud patterns this time.

Imaged with PGR Flea CCD at 66mS and f20 with C8.
