G'day Bojan,
I had an opportunity to give my Optalong L-Enhance a side-by-side comparison with my new ASKAR C2 dual band last night. It was a full moon (minus 1 night) but even so, the results were clear enough.
I imaged using a ASI071MC on a SharpStar 94EDPH (x0.8 reduced).
The absence oh the Ha signal in the ASKAR image certainly brings out the O3 and allows that little bit of S2 to come through as well.

I do not yet have the skill needed to extract the 3 NB bands and combine into a full Hubble palette. That is a task for another day.
