I finally got the Lunt 60 pressure tuned 1200 today. As a follow up, which blocking filter has better transmission? Will I also need an IRUV cut before the Quark? Also picked up a US made pst and AOK Swiss adapters. I’m thinking of using it for double stacking the Lunt with this also. Does anyone have any experience with either one of these configurations? Thanks again!
