Optolong L-Pro Light Pollution Broadband Filter

[bomberbaz]

Anybody used this either visual or imaging wise I would be interested to hear feedback.

A look at their light transmission charts doesn't really tell me much other than it seems to let far more light through than either a Optolong's std light pollution filter or their UHC with no other variance on what it doesn't let through.  There is also no apparent reason why it lets through the extra light as it doesn't seem to affect according to the transmission charts. https://www.firstlightoptics.com/optolong-filters/optolong-l-pro-light-pollution-broadband-filter.html

Lets face it, the main reason for any filter is to reduce unwanted photons from a specific wavelength so I cannot see why this is so special and why it warrants such a price tag but I hope to be enlightened (sorry no pun intended)

Anybody got any info?

Cheers, Steve.
