Hercules Cluster M13 (84 minute equivalent exposure).

From a dark place, you can see this one in the northern sky just by looking up. Of course, having more than 100,000 stars in the cluster helps brighten it up a bit.

edit: Back in 1974, radio messages were sent out into space. The ‘Arecibo Message’ was sent toward M13.

Look! Up in the sky! It is a comet...

C/2017 K2 (PanSTARRS)

Like just about every other comet out there, this one moves around a lot. I have seen it a few times since its discovery was announced and got this image on June 28, 2022. It was moving across the Ophiuchus Constellation. It still is, and should be visible for some time yet. I have seen estimates that it will be visible until September, 2022. This is the equivalent of an almost 58 minute exposure.

Coat hanger...

Welcome, dear visitor! As registered member you'd see an image here…

(This is the equivalent of a just under 28 minutes exposure.) This is Collinder 399 (Cr 399), The Coat Hanger Cluster, also known as Al Sufi's Cluster or Brocchi's Cluster. Except it is not.

Cluster? Constellation? Something Else? A lot of astronomers have studied and debated what this group of stars is as an astronomical thing. The most recent studies tell us these ten stars form an asterism -- a bunch of stars that form a pattern in the sky, but have no other connection to each other (The Big Dipper -- Ursa Major is an example of an asterism).

The Coat Hanger Cluster is easy to see using binoculars and small telescopes, it is in the constellation Vulpecula.

I put a new version of Bode's Stuff on page one of this thread. The framing is better suited to that telescope's focal length. The dust lanes still are not showing up very well, but there is always next 'galaxy season' 😀.
