Description

This is a reprocessing of an old untracked data set that I acquired during a hike to Mount Champaquí back in 2019.

The shelter near the summit was around 2200m above sea level, and the area is quite dark, SQM 21.82. The view was spectacular, and all the equipment I had to carry on my backpack, so I was limited to just my camera and a regular, untracked tripod.

This was my first time imaging at a dark site, and the data I acquired has lots of issues, mostly because I was also just getting started with AP. You can tell from the poor framing ;-)

This little integration from home, however, would never get nearly enough data to be able to see the dark dust clouds. Dark sites are awesome.

If you look at the image without zooming too much, it's really nice. If you zoom you'll see I used too long an exposure length for an untracked shot, even at 28mm FL. I love this image nonetheless since it's a reminder of all the goodies of a dark site.

An interesting bit of trivia, is that I had never been happy with the processing on this image before this attempt. The kit lens has a lot of geometric distortion, and the significant drift in the subs caused all sorts of registration errors. I just recently developed an optical flow registration algorithm that compensates for geometric distortion, and that's what allowed me to succeed this time around.

The morale of the story: reprocess your old data, especially data you weren't satisfied with the first time around. You might be surprised.
