Chroma 3nm ha worth it?

[Trentend]

Wondering how this would compare to an Antlia 3.5nm which is in my current inventory for NV. The Chroma seems to be the go to filter at this band, albeit with a chunky price tag. Not sure if I’d notice a step change between the two?

What other filters have you got?

3.5nm Antlia, 7nm & 695 baader, 12nm and 642 Astronomik. The chroma (if I went down that route) would be a replacement for the Antlia.

I have an Antila 3 nm in bound and a Baader 6.5 nm f2 filter. No chroma to compare with…
