As for the indirect sky glow from the Moon, I am sure it is simply a case of there isn't much coming through the few nm band width of the filter and the less the band width the less there is getting through?
I think Gerd ahs been working on them for a while and I know he is very happy with the result, very high transmission even at 6nm something like 95% or more I believe |
I think I smell an upcoming side by side review (12v6)
