Hi Ray,

Just letting you know that I plugged in numbers to your spreadsheet to the best of my knowledge, and the graph confirms what I was getting before, that about 15-minute subs in my case are optimal and that there is minimal gain past that length. I guess sky brightness is the largest uncertainty for me, but with narrowband it should be comparable to an extremely dark site?
