Quote:Keith, was the dust from the HA channel or the RGB that you typically see? If it is from RGB then it probably does not show up due to the LP in my area. I kept the subs to 10 minutes in RGB so I wouldn't have to contend with the sky glow. I did not process it out, it wasn't there!

I kept the subs to 10 minutes in RGB so I wouldn't have to contend with the sky glow. I did not process it out, it wasn't there! That would explain it if most of your signal was coming from the Ha. I don't have the lights from my version on the computer I'm using now, but as I recollect the dust was mostly coming in the L and RGB light frames, and I'm in a Bortle green zone so the sky glow background isn't too overwhelming. ...Keith
