GoKidd How can I add an IR-cut filter to my ASI585MC?
This is one way to insert a 1.25" filter to the light path of a ZWO pancake camera:
You can get that M42-to-1.25" filter adapter from places like ScopeStuff and even ZWO, AliExpress and eBay.
No, don't do that; there are many way-better, and well-documented UV-IR Cut filters from Astronomik, Baader, Optolong, etc.
Just like with the photography world, you don't want the filter to be the limiting factor of the entire expensive imaging chain. Most Luminence filters (from an LRGB set, for example) will also cut unwanted UV and IR (like the set from Antlia, even though they don't sell an individual UV-IR Cut filter).
If you want to knock yourself out in terms of quality, go for the Chroma or Astrodon 1.25" Luminence filter.
