I need to get a set of LRGBs at some stage for my CCD.
Years ago, the SBig filters, Astrodons, Astronomiks etc were the usual choice. Now, not so easy! Optolong, ZWO, Antlia, Chroma$ (and Astronomik and Baaders etc) etc. To be clear, Chroma is way out of budget.
Welcome any input…
Yep, very good. The unmounted filters do have some edge blackening to prevent light leak, but I'd recommend mounted filters if you can (I should have done that)
