It's going to be easier to get good SNR in blue with the Pleiades because there's lots of signal!

My thoughts are:
  • always do sky limited subs for L/R/G/B (may not be feasible for NB)
  • try to avoid a big imbalance between SNR in the colour channels but rough is good enough and if you're doing Lum then it's less important
  • for NB the signal in each filter is much more variable and target dependent - just do the best you can and rely more on processing to make up for poor quality masters (tone mapping is a big help)

Cheers,
Rick.
