Errata, sorry.

In this post the curves popping up are those of the Lumicon UHC filter.

thanks for the update on the Lumicon web site.
Not sure, if Lumicon has made a technology remake, but below are the curves of the older Lumicin deep sky filter

Astronomical filter curves

Looking like a good choice for the visual observations, even if the purists would worry about the filter leakage in 400nm - 430nm.

Looking forward to more of your reports on using this filter, as it helps all of us when making a purchase decission.

to display the Lumicon Deep Sky Filter against the Astronomik UHC, both stacked with IR block.

The Lumicon Deep Sky Filter corresponds roughly with the Baader UHC-S, I also have in my collection.
There have been even rumours, if the both filters, the Baader UHC-S, and the Lumicon Deep Sky were not from the same production batch, as some of the Baader filters (and also Astronomik filters) have been rebranded for the non-European markets, from time to time.

Best,
