A Rose by another name ... is a Screaming Skull!

NGC 7789, a star cluster located in the Cassiopeia Constellation, is called Caroline's Rose Cluster in honor of astronomer Caroline Herschel who discovered it in 1783.

It also goes by the name The Screaming Skull Cluster. I must lack the cultural background or imagination, I have viewed this cluster through different telescopes at differing times of the season, but I just do not imagine a skull, much less a screaming one. Oh well.

This is the equivalent of 84 minutes, 40 seconds of exposure.

It also goes by the nicknames Ghost Cluster, Star Mist Cluster, Herschel's Spiral Cluster and Crab Cluster, maybe star mist might come close as a name...

NGC 281 This is the equivalent of 116 minutes exposure time. NGC 281 also goes by the name of the Pacman Nebula. https://solarsystem.nasa.gov/resourc

This is the exposure equivalent of not-quite-but-almost 61 minutes. (Part One of Two)

Orion has plenty of interesting parts to see; nebulas, bright glowing stars and whatnot. Orion is not the only neat thing in that part of the sky, the Rosette Nebula is close by and it is certainly neat to see. But there is also a Cone, a Christmas tree and a little variable thing as well.

This is the equivalent of 112 minutes and lots of change worth of exposure.

NGC 2261, Hubble’s Variable Nebula is named after astronomer Edwin Hubble, who also has the big space telescope named after him:

The Cone Nebula, NGC 2264, is actually much larger than the part seen above, the part in the images is what gives it its name:

NASA had some fun with the Christmas Tree Cluster (The batch of stars in the “lower” part of the Cone Nebula), they rotated the image upside down — or right side up if you view it in the land down under — x-ray colored the nebula green and animated the Cluster’s stars. They have a player on their page:

Cropped a lot, just trying to get a vulture in the same frame as the moon.  Looks weird, but it was fun trying to get the shot......70-300 XT-5.

Busy as a bee… Not far from Castor and Pollux in Gemini, actually just in the next constellation over to the “left” in Cancer, is Messier Object M44, The Beehive Cluster:

M44 is fairly easy to find visually or when using binoculars or small telescopes. This is the equivalent of 58 minutes of exposure.

"Will you walk into my parlour?" said the Spider to the Fly” * 

Back on page one of this thread, there is a post showing a quick exposure isolating IC 405, The Flaming Star Nebula. That section of the sky has so many things to see it is almost a tourist-oriented nature-viewing area.

Some of the highlights include tadpoles, starfish, spiders, flies, pinwheels and more.

This is the equivalent of just about 56 minutes of exposure.

Will the spider once again coax the fly into its parlour? Will the fly escape the machinations? Their exchange is in the sky for us to ponder...

Big Bear, Big Dipper...

Every now and then one of the images I post will have an asterism, which is just a pattern in the stars that is interesting to see, but the stars have no relation to each other unlike stars in constellations. There is a famous one where both happen at the same time, the stars are in an asterism and in a constellation...

This is a screen capture from Stellarium, with annotated star names added on top. All of the stars are part of constellation Ursa Major. The blue-ish colored lines and the white-ish colored lines connect the main constellation stars, the white-ish colored lines alone form asterisms. The orange-ish colored labels are for the stars in the two asterisms.

This is the equivalent of an 80 seconds exposure.

As a side note: Alcor and Mizar are a famous double star pair, very easy to see visually or with binoculars or telescopes.

But Sirius-ly Dog Star...

Of all the neat and interesting or just regular things to see in the night sky, Sirius, The Dog Star in constellation Canis Major, is considered the easiest to find, because it is the brightest star in the night sky. Being close to the Orion Constellation also helps make it easy to find. Sirius is going to continue getting brighter because it is moving toward us, in about 60,000 (60.000) years it will be a very close neighbor.

(This is the equivalent of 28 minutes, 20 seconds worth of exposure).

If you can find Sirius up high enough in the sky, then just below it you should be able to find Messier Object M41, The Mini Beehive Cluster (related in name to Messier M44 the Beehive Cluster). Sirius and M41 are companions, tracking together across the night sky. There are some other interesting objects, clusters and nebulae in that region, probably the most famous is Sh2-308, Dolphin Head Nebula.
