I've been neglecting you a bit. TikTok takes up quite a lot of time.

So, here is the open star cluster M39 in the constellation Cygnus. From my Messier Marathon. That's why the integration time is short, just enough for the record. But I was surprised by the dust (or gas?) that showed up in the background. F4 is no joke after all... And why did I sell it?
