I usually go at least as long wrt time for L as for R+G+B, although still getting a feel for it.

I find that 40+ subs per channel hits the range when the channel output is cleaning up nicely. With galaxies, hundreds of subs to really target the SNR. This is with my 1600 of course. Prefer a few more with the 178 and its tiny pixels.

YMMV though as your scope is much bigger and faster (thus higher SNR!) than my little refractor
