Thanks Don.  I see you applied more min filter to reduce the stars and darkened the background.  While it made the nebulosity jump more I look at a balance of highlighting the object and trying to make it still look natural in the sky.   I applied about 6 or 7 - 1 pixel min applications that I reduced each to 20 % to get the reduction of stars that I got.  I tried more and decided to stop where I did.   Every person has a very different philosophy of what they like.  I wish I had gotten more exposures for each panel but I am pleasantly surprised what I got with 2 hours each.   I really like the CMOS cameras sensitivity and think I want to try more mosaics.  They are so easy to stitch in Photoshop.  If I get some imaging time this winter i may try an Orion mosaic.
