another try at the "ear"...
25 ten minute subs at f/6.8 on the 12 inch LX 200 classic. Cropped
slightly (about 8%) to lose some bad stars
acquired, calibrated, and stacked in Nebulosity 2.1.5 post processed
with Photoshop CS3.
I still don't have star colors, but the fringes of the nebulosity
are much better than earlier attempts..
look also at my first try
at wide field H alpha of this region, in work.
