Description

I had written the imaging script for this target before I got to PA but I had pretty much relegated it to the cutting room floor before I arrived in favor of other targets. I believe the target that had beaten it out was either the Veil or Trifid. When it came time to imaging though, I decided those targets should wait until later in the year when they are higher and so better positioned for imaging. For that reason, I made the decision on the fly to switch to the North America Pelican complex which is the only deviation from a very regimented plan for the trip which I had planned to the minute, 2 months prior. Boy am I glad I made the decision to swap because this is easily the cleanest data I have ever collected. I could tell that is was good as the subs started to come in. Each 1 minute sub looked like a stack of several hours back home. I guess I shouldn't be supprised given the lack of light pollution and a filter that denies entry to all but the finest Ha and Oiii photons.

Given how clean the stack was, I decided to manipulate the image as little as possible. No star reduction and just a light amount of playing with saturation and contrast was all that was needed. I usually reduce noise in PI before stretching but the usual settings were destroying the data so I stretched before noise reduction for the first time ever. Didn't seem to hurt the image as my next stop was Topaz Denoise which seems more affective anyway. Overall very pleased with the image. If I can match this detail every time, I'll be very happy.
