Scutum from Rancho Hidalgo

Here’s the result using the Canon 60Da on my little tracker head.  I spent a lot of time fooling with these in Pixinsight and then Photoshop.  Unusual for this part of New Mexico, I had problems with gradients due to smoke from wildfires in Arizona.  (See https://www.jjmcclintock.com/?p=139) I believe this is stacked from  5-180 second exposures. Images were collected May 18, 2012.

Scutum region, 5 x 180 sec, Canon 60Da; 28-135 lens at 28mm; f/8, ASA 3200
