This is a 10nm filter sold by AliExpress.
Do you think there are many performance differences between Andover-396-5 nm?

Re: alie`s 395-10nm
hard to tell. Christian should have the experience to answer this. Looking at the bandpass I would say it should not make such a big difference contrastwise. The Baader K-Line filter also produces good images (8nm).

Looks very similar to the K-line in bandpass, higher transmission but worse blocking.
