Thanks for the alternate rendition, Moose. Wish the tiff hadn’t vanished. I uprezzed the only little jpeg I had with Gigapixel AI and thus
some star artifacts. The monument had a minor alignment issue overlaying the stacked sky and foreground shots. I was already 3 hours into it.
Many use a utility to eliminate the green cast— typically sky glow from exited oxygen at 558nm. Sensor is very sensitive there.
Back 5 years ago when I started, wide angle astrolandscape was a very tiny niche. Now there are plug -ins to “make small stars.”
This enhances the prominence of the MW. Accuracy is often not the goal.
Don't forget Topaz Sharpen AI. Here's a roughly analogous subject. It has both pinpoints and dim, subtle structures, and
much more serious motion blur than you would allow in your astro work.
Look particularly at images 3 & 4. The OIS wasn't up to 720 mm eq. at 1/125 sec. and the 1/2.3" sensor is noisy. Sharpen
AI has done magic!
Accuracy? I dunno. The very reason I wasn't carrying The Big Guns is why no comparison.
😉
BTW, taken at Dogtown, 9/13/2019.
