In the next post within this thread, I am going to try to post a picture here, as an "appetizer." If it does not work, I will try again with a different technique.
It turns out that expanding the image is not very worthwhile -- it first redirects you to a hosting site, and then if you click it again, you get a huge photo that is hard to view because it is too large.
30 seconds at an ISO of 3200. And I have an incandescent flashlight -- 30 years old -- that sheds a warm light for a quick paint job on foreground objects.
If you like night shots, check out the blog link -- there are others.
By the way, you can do this without a tripod -- just put the camera on a picnic table!
