This is an extension of my data from last week, but taken at a shorter focal length, and with some more time to consider processing.  This image was taken at 70mm, f/2.8, ISO 200, 30s, stack of 10 images, with a Nikon D5600, also from Mt. Laguna, CA.  Click for larger size (and ignore the jpeg compression artifacts!).

Thanks to those for the "likes".  And here is a reprocessed version of the same image that I like better.  Aside from the different orientation (I think the vertical looks nicer in this case, reminiscent of an ascending rocket), the colors are also different (and more accurate, I believe.....the previous version had an overly strong green cast).  The second version was processed in PixInsight, with which I am using the free trial period.
