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.

Guided with the DSI pro I, PHD, and shoestring GPUSB through the Explore Scientific ED80 apo.
