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' 😀.

Eye of Croc or Eye of Cat:

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

Simply register for free here – We are always happy to welcome new members!

This is the equivalent of a just over 64 minutes exposure.

https://www.messier-objects.com/messier-94-cats-eye-galaxy/

Messier Object M94 is called The Cat's Eye Galaxy by some and The Croc's Eye Galaxy by others. It is located in the general direction of the Big Dipper (Ursa Major)'s handle. 'Ol Cat's Eye has an unusual shape which may or may not be related to dark matter being in the galaxy. This video shows an over 550 minute exposure and explains some of the controversy about M94:

Jabbah: The Horse's Blue Eyes

This is the equivalent of a just over 78 minutes exposure.

The big blue star is Jabbah. It is located in the Blue Horsehead Nebula (IC 4592) as part of the Scorpius Constellation. Jabbah also goes by the name Nu Scorpii Aa which is probably why some folks prefer to call it Jabbah. The color from this star group is reflected by the somewhat large nebula and gives the nebula its blue color. Seeing the stars is not too difficult, but you need very dark skies (and a "wide angle" telescope) to see the nebula.

Sadr in Cygnus:

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

Cygnus (the Swan) is easily visible this time of year even in some light polluted places. The brightest star in the constellation is Deneb. Sadr is at the base of the Cygnus' neck and is surrounded by some interesting dusty nebula areas. These are the equivalent of a just under 89 minutes exposure.
