Sunset timelapse video and reprocessed Dumbbell Nebula

After days of grey, clouded skies, last night’s sunset was finally visible. So I positioned my camera in my window frame and let my laptop take 200 photos in a little over an hour:

When played at 20 fps, last evening’s sunset in timelapse looks like this:

Also, I worked a little more on my Dumbbell Nebula and got a pretty decent result considering the relatively low number of short exposure frames. After stacking, I masked out some of the noise, applied some high-contrast tone curves and made a star overlay, which makes the stars ‘pop’ and even makes them somewhat hexagonal (round with 6 small diffraction peaks due to the 3 bars in my telescope).

For reference, the original unprocessed frames look like this:

After exposure adjustment and noise reduction of the reparate images, they look like in the video below. The final image is the stacked image above.
