Thanks Andrew, I'm glad you liked it.
I've been looking into the filter situation and the only one that I can see that's suited to Brisbane LP, where it most street lights are Mercury vapour (M80 & M50), is the IDAS LPS-P2 - very exie! I did look at the spectral response of the Neodymium which is cheaper but it seems to let in a fair amount of Hg while hitting the Na.
I need to get out to a dark site me thinks!!
Cheers,
Mario
