Difference between the 2 flavours of Astronomik RGB filters?

As per the title, I'm struggling to discern the difference between the 2 flavours of RGB filter sets produced by Astronomik (other than one has a luminance as well!)

The technical spec's don't give an obvious contrast.

• Deep-Sky RGB Color Filters
• L-RGB Typ 2c Color Filters

Thanks in advance.

I think it's the interference of the different colour wavelengths that differ. Not an expert though!

For anyone else wondering, I heard back from Astronomik support, who said:

For deep sky imaging with an apochromatic refractor the Deep-Sky RGB set is recomended. The L-RGB set gives you the best color rendering of all availiable RGB filtersets. The main benefit of this is in planetary imaging.
