Which filter to choose?

[Jinx]

Well it seems that my original purchase Baader Neo Moon and Sky Glow 2" is out of stock, so I am now reconsidering its purchase.

Having just picked up my Ultrawide 9mm EP and big barlow, I was hoping to do some lunar observing - using the aforementioned new filter.

However, when looking at the UHC-S filters for future purchase and DSO views, I wondered if I could perhaps just go for this and forget the Neodymium one.

I presume Baader are worth the extra price than Skywatcher, but haven't worked out if the booster one is worth more over the standard one (see earlier thread).

I really don't want to waste 50-60 quid by doubling up on these filters. Oh and I really can't interpret absorption spectra!
