I have bougth an used filter #2458380, but on the body filter, in the original Baader label, is written "H-Alpha 45nm Passfilter 2" wIR-cut.
Since in your catalog the #2458380 is 35nm filter, my question is: there where an old version with same P/N but different band?
Thanks a lot in advance for your help.
best regards

Does the filter block IR radiation right down to 2400nm. Solar radiation extends that far. KG3 heat absorbing glasses protect down to 2400nm. On your UV IR blocking filter you say it is better than KG3 so that implies that goes down to 2400nm.
