That looks really, really nice Gary

Regarding the luminance filters, I am not sure. I have ED80 + flattener ATM and I used it with Baader UV/IR-cut filter in the past, until I dropped the filter and smashed it . That worked well to remove bloated stars.
The Baader UV/IR-cut seems to have the same spectral response in IR as the Astronomik L2 but it is somewhere in between the L2 and L3 filters in the UV range.

I am tempted to say L2 but I will post a question on this forum regarding my setup. Hopefully one of the more knowledgable people will be able to give advice (and could probably also help you with your decision).

Brendan, I hope you get better soon. Back pain here as well but nothing very serious.
