Description

LHaRGB composition. L data taken under about 1.4" seeing. OIII exposures were also taken, but it turns out the OIII signal from this nebula is too weak to make a big difference.  This is my first image processed with PixInsight's new gradient correction tool. It works well, but it requires some parameter tuning.

Rev.B:  When I reviewed the first uploaded version, I found an embarrassing mistake: I forgot to turn on a sharpened layer in Photoshop before I flattened the layers. This made the nebular part looks kind of blurry.  I corrected this problem and re-upload it.  Rev.B is the corrected one.
