This is a good one, considering I didn't aim for anything interesting but just a random area of night sky where no trees or buildings are blocking the view. I mean, it's pretty random.
You can actually tell the Lyra (Fig 2) and the Sagitta (Fig 3).
And all of this, is shoot on an action camera, costs only 350 USD. Wow, I'm deeply amazed.
BTW I'm using Sequator for stacking, looks like it can handle the lens aberration pretty good.
