Is there an up to date reference about the various photometric filters. I am considering buying a set (B.V,R,I) of photometric filters, 2 inch diameter. A quick search identified Baader and Uptolong as potential sources. I would appreciate to know about possible other manufacturers. Also, opinion about the performance of these various filters would be appreciated.

Thanks,

Damien

Damien,

I am also hoping to see something comprehensive. But that may be a long time coming!

Here is a short review of Baader: https://www.aavso.org/baader-bvri-bessel-filter-testing

I have heard that Chroma's new filters are generally good, but I lack solid evidence of that.

If I were in need of photometric filters at this time, I personally would only go with Baader or Chroma. But that's just me...
