Description

I used two sets of data for this shot, 85 frames shot with the Lpro at 300s, and 48 frames shot filterless at 180s.  Processed each in PI, then used luminosity blending mode in PS to combine; the filterless data has superior color, the Lpro data has superior detail.  The combo worked well.  I should repeat the experiment with more filterless exposures to equal the same overall integration time to see how they compare.  Still trying to find the right process for dealing with light pollution on broadband targets.
