IR cut-off
Eric,
Interesting observation!
If I can get the chance I'll put the Baader on the spectroscope and see if I can measure the actual cut-off. The only CCD's I have which might get out to 1100nm is the webcam and or the MX7C.
Keep you posted.
(BTW the ROSCO UV-IR appears ( at least on paper!) to cut everything above 700nm)
