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

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

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.

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:

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.

A Dragonfly, ..., An Owl, ...., ET!

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

Located in the Cassiopeia constellation, NGC 457 is known as the Dragonfly Cluster, or as the Owl Cluster or as the ET Cluster. 'Ol Dragonfly can easily be seen in the Northern Hemisphere this time of year with low powered binoculars. This is the equivalent of a 95 1/3 minute exposure.

Two for the price of one, ..., Doubling your Cluster fun!

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!

Together NGC 884 and NGC 869 form The Double Cluster in the Perseus Constellation (close by the Cassiopeia Constellation). This is the equivalent to a 49 minute exposure.

The Double Cluster is popular with the binocular and/or small telescope using observers, and in dark skies it is quite visible just by looking up toward Cassiopeia.

The Triangulum Galaxy -- Messier Object M33:

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 110 minute exposure).

M33, a pretty, little, close by galaxy, is actually connected to The Andromeda Galaxy M31 (shown on the first page). Some speculate that sometime in the future, these two will crash into each other, or they could just keep going their separate ways. Speculation gets rather fanciful regarding this notion.

More locally, visually seeing M33 is used as one of the criteria for determining a place's Bortle Scale Number, a measurement of how dark the sky is at night in that place vs how much light pollution or sky glow there is at that place. If you can see M33 without using binoculars or telescopes then that place has a low Bortle Number -- this also works the other way, if you are at a dark sky site and you can see M33, your night vision is in good shape. 😀

That's the spirit 😄.

Maybe next time try using a mount for your camera instead of hand holding it, that way it is easier to get better focus for the stars. 🙂

Fish Head Stew

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

This is NGC 896 (also known as IC 1795) The Fish Head Nebula. Fish Head is located just next to the very beautiful Heart Nebula (IC 1805), so close that it looks like it is connected to it. This is the equivalent of a 102 minute exposure.

Rigel and the Witch Head Nebula:

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 typically how IC 2118 (usually called the Witch Head Nebula) is presented, upside down. In space though, there really is no such place as "up". The nebula is a reflection nebula; which means it does not give off any light on its own, but instead reflects the light from stars, nearby street-lamps, errant flashlights, etc. 😀.

The Rosette Nebula has a lot of moving parts. Tucked away inside is a small cluster, NGC 2244.

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 exposure equivalent of just under 66 minutes. The cluster is surrounded by dust lanes, other nebulas and nebula stuff. Here is a slightly more brightened version:

edit: This is a bit more distant view for the Rosette Nebula (using the feet to zoom does work 😀).

This is the equivalent of a 19 minutes, 35 seconds exposure.

Another fine chapeau ... Thor's Helmet (NGC 2359).

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 52 minutes, 30 seconds exposure.

Other known aliases include the Duck Head Nebula, the Flying Eye Nebula, the Duck Nebula and the Whistle Nebula.

Like M104, the Sombrero Galaxy, Thor's Helmet is certainly large enough to keep the hot sun off of your head. The nebula is actually a big 'ol bubble formed by a solar wind blowing from a star through a gas cloud.
