Baader cmos optimized filters - new or rebranded?

[GTom]

Question here for Baader's LRGB-set: older stock says "CCD optimized, no haze, no reflections etc," new stock is "cmos optimized". Is there any practical difference between the two?

think I answered this one recently but there is a difference in the specified band pass for the blue filter 400nm for the new one Vs 380nm for the old one. There may be other tweeks to the coating but all in all you can still use the old CCD set on CMOS cameras without issues as I do. 

So no it's not a pure rebranding.

Thank you Adam!

For planetary work I'd lean to the new "B" filter, for deep sky to the old one, to make use of as many photons as possible 🤣. Will be using an SC and a triplet apo for these jobs, I think I'll be fine with the "old" design.
