Second Attempt At Astro Time-Lapse: Orion Setting

This is Steve. My second astro time-lapse video: Orion setting just after dark.

The photo above is the first frame, while there's still a bit of twilight; northern hemisphere, facing south. Orion is just to the right of center, with his belt just below center. Betelgeuse (yes, just like "beetle-juice") and Rigel at top and bottom a little less than a third from the top and bottom of the image. That's Sirius off to lower left, the brightest star in the night sky.

See FIRST ATTEMPT AT ASTRO TIME-LAPSE for how I do this.

These are 25-sec exposures on roughly 95-sec intervals, f/5.6, ISO 1250, 18-45mm lens at 18. I had the exposure on the app set to 90 sec, so I'm not sure why the discrepancy.

There are some interesting shooting-star/satellite/airplane streaks.

Here's the full video, generated at 24 fps. Watch it at 0.25x speed or hit the spacebar repeatedly to start/stop and play through it slowly, since the whole thing is only 119 frames from 3 hours of imaging, for a total play time of 5 seconds. Also be sure to watch at 1080p, on a high-quality monitor, because anything less loses a lot of detail; it looks a lot better on my built-in Mac display than on my inexpensive separate monitor even though both are 1080p.

And look closely, the middle star in Orion's sword, there's M42, the Orion Nebula!!! All grey-scale and full of noise with no image processing in this blowup, but there it is! In a super wide-field image! The mind boggles!

Here are some interesting frames, a full-night for comparison to the first one, and most of the streaks. I believe the triple parallel lines are airplanes. There's one with a regular line of 19 points diagonally across the frame, perhaps Starlink satellites in train? Also one with multi-streaks in different directions, it's a busy place up there! It's fun to cycle through these in the gallery view.

This is what my camera looked like when I went out to get it at 5am, with the temperature 33 F and the battery dead (that's the waning gibbous half-moon rising through the trees in the background):
