Wake up and smell the Saturn…and then shoot 180,000 video frames of it through my telescope.
2 weeks later:
Finally finish processing and share, because sharing is caring!
How it was done
This image of Saturn was created from ~180,000 frames of video collected on 2013-02-13. Saturn was about 35 degrees in altitude at my observing location, in moderate seeing conditions and atmospheric disturbance. The video frames were stacked using Autostakkert2 and post-processed in Photoshop CS2.
In particular, more than 40 2-minute video clips were stacked independently using Autostakkert2 video processing software, running in WINE on Linux. I used the 1.5x upscaling feature on each clip using 30%-50% of the frames. Then each clip’s stacked output TIF was re-stacked together to create a final, smooth, image that could be heavily sharpened in Photoshop CS2 to bring out hidden detail, without causing too much noise.
