Celestial Fireworks

With the lousy weather this February I decided to reprocess a couple of images taken back in 2011. Can't get decent skies this week or next according to long term weather outlook.
This image was taken with my original 10" F14.6 Mak-Cass. Who says you have to shoot at F5 to get anything. This is with my old STL11K camera, which is still working great.

Wow! That's incredible Roland.

Wow that is one heck of an image! Do you recall any exposure times, even overall?

  Just match pixel size to focal length. High qe camera helps too.  Some of the new backilluminated cmos cameras allowing binning would be excellent.

Back then I almost always did 20 minute exposures.

In the "cleaning up" domain.... Back in October during the Mars opposition, a friend told me about Topaz Labs DeNoise AI that removes noise and sharpens images. <https://www.topazlabs.com/denoise-ai>

It works really great! I've attached a slit-screen grab showing a portion of your image and a preview of what it would look like after DeNoise AI did its magic.

Your image doesn't have much noise to start with, but DeNoise AI would have slightly sharpened it and brought out a bit more detail. I've seen it remove a LOT of noise in some of my images, and it always improves the details.

It greatly improved my pathetic Mars images last fall.

Topaz Labs also sells Gigapixel AI to resize images, and Sharpen AI to sharpen them. I have Gigapixel, but don't use it much because it takes a LONG time. Just reducing a 4500x3500 image to 800x600 takes 10-15 minutes! I suspect it runs faster on "normal" (non-astro) photos.

Sharpen AI appears to be a new product, and I don't know anything more than what's on the website.

Clear skies.
