The monkey head nebula - ngc2174 is an emission nebula located in the Orion Constellation. It is associated with the stellar cluster ngc2175. It was given this name as you can see well from the photo, the face of a monkey.
I decided to process this photo with the Hubble Palette technique, and therefore, with fake colors to highlight better the emission areas of the various chemical elements that compose the nebula.

Robert Burnham, Jr. describes this beautiful object as follows:
“Charming group whose arrangement suggests the outline of a butterfly with open wings.” Nothing better than a little "poetry" to describe such a prominent object.

In 1654 Italian astronomer Giovanni Battista Hodierna was the first man to record this beautiful star cluster in the scorpion constellation.

In 1764 the French Charles Messier includes in his catalog as Messier 6. Under good conditions, it can be seen with the naked eye, in contrast to the dark regions surrounding the star cluster. It has an apparent magnitude of 4.2 and an estimated age of 100 million years, at a distance of approximately 1600 light years from planet Earth.

The brightest star in the cluster is BM SCORPII. It is cataloged as a yellow / orange supergiant, and is considered a semi-regular variable, as it is of the spectral class K0-K3, its magnitude varies from 5.5 to 7, in periods of 30 to 1100 days. The hot blue stars of the cluster belong to the spectral class B4 and B5.
The cluster to the right of this image is NGC 6404.

The most intense part of the image, which I had the idea from the outset to highlight, is part of an extensive emission nebula called: Sharpless 12.

The information about this object is very scarce, but I will try to put as much information as I can about this object. All ionization occurs due to the O-Star (O7V + O7V) HD 159176 binary star, which is located in cluster NGC 6383 and does not appear in my image.

A fact that caught my attention and that when we talk about astronomy we always go back to the past, most catalogs are hundreds of years old, but Sharpless is not even a century old. Stewart Lane Sharpless (born March 29, 1926 in Milwaukee, January 19, 2013) was an American astronomer who studied the structure of the Milky Way, professor emeritus of the Department of Physics and Astronomy at the University of Rochester. The first edition of its catalog is from the year 1953 (SH1) contained 142 objects. The final version, published in 1959 (SH2), contains 312 objects.

NGC 6164 has an appearance similar to what you would see in a planetary nebula. It has a gaseous shroud that surrounds the central star. These typically have shock-waves, and often highlight where they brighten showing where they are interacting with the interstellar medium.

The extensive outer halo would have to be my favorite part of this image. The outer halo is very dim and certainly proved to be a challenge to reveal it with all the tiny filaments with blue and teal highlights and a bit of red where Ha is present. There is a feature that I initially believed to be a light leak. On the left side of the image, there is what looks like a straight line. After looking through many images, it’s definitely real, and not a light leak.

NGC 6164 is 4,200 light-years away in the constellation of Ara. It is about 21 X 13 arc mins, at magnitude 11. It contains a very bright O-type star about 40 times as massive as our sun. The nebula in the center spans around 4 light-years and has an interesting bipolar symmetry, this is all framed nicely in the larger outer-shell, all set within a beautiful star-field.

This is a very interesting area in the Taurus Molecular Cloud featuring many dark and reflection nebulae. The main subject in the center is Barnard 7 (the dark nebula) and LBN 782 (the blue reflection nebula). To the left side is vdB 27, illuminated by RY Tauri, a young variable star. To the right is another reflection nebula illuminated by variable star CW Tauri. Peeking through the dust 186 million light years away is the galaxy IC 359, in the bottom right. All in all, a lot of different things to see here!

The young open star cluster NGC 7129 is embedded in the bluish reflection nebula vdB 146. Due to it's shape the reflection nebula is called "Rosebud Nebula" and is located in the constellation Cepheus. The young stars have blown a large, oddly shaped bubble in the molecular cloud that once surrounded them at their birth. The rosy pink color comes from glowing dust grains on the surface of the bubble being heated by the intense light from the young stars within. Also some Herbig-Haro objects can be identified in the reflection nebula. Their shape and pinkish red color is characteristic of glowing hydrogen gas shocked by jets streaming away from newborn stars.


NGC 7142 is an open cluster about 6,200 light-years away. With an estimated age of 4.5 billion years, he is one of the oldest known open clusters.

The fine Halpha filaments on the left side of the image are part of the supernova remnant SNR 110.3 + 11.3.

INFO
IC 1396 spans hundreds of light years at distance of about 3000 light years in constellation Cepheus. The famous formation of glowing gases, the "Elephant's Trunk Nebula" can be seen at four o'clock position. This is an active star formation region and it has several massive young stars inside it, coursing the ionization of elements of this emission nebula.

IC 1795 - The Fish Head nebula

IC 1795 is an area of gas and dust and also a star forming region in the northern constellation Cassiopeia.
IC 1795 is an extension of the larger Heart nebula or IC 1805.

The brightest part of the nebula has the designation NGC 896 in the New General Catalogue. It is classified separately because it was the first part of IC 1805 to be discovered.
