An Edge-On Spiral Galaxy in Coma Berenices

NGC 4565, sometimes referred to as the Needle Galaxy, is an edge-on galaxy in the constellation Coma Berenices. One can see the galaxy's yellowish central core, which is divided by obscuring dust lanes running the length of the equatorial plane. Total exposure was 10 hrs 20 min taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg CCD camera (Astrodon Gen2 filters) on a Paramount ME in Mayhill, NM on the nights of 8, 15, 16 May; 17, 18 June 2018 ( 21 x 1200 sec lights; 4 x 1200 sec R; 3 x 1200 sec G; 3 x 1200 sec B all @ -20 degrees C; 24 darks; 128 bias; 128 flats for each channel). Processed in PixInsight 1.8.5.1353 Ripley (x 64). An annotated image can be found on the Amateur Astronomers facebook page https://www.facebook.com/AmateurAstronomersGroup

NGC 7217. KG Observatory.

NGC 7217 is an unbarred spiral galaxy 50 million light-years from Earth in the constellation of Pegasus. It is receding from us at approximately 952 kilometers per second.

It is an active galaxy with an active galactic nucleus (a compact region at the center of a galaxy that has a much higher than normal luminosity, probably caused by accretion of mass by a supermassive black hole at the center of its host galaxy).

NGC 7217’s main features are the presence of three optical ring-like zones of stars concentric to its bright nucleus. It has a tight, flocculent spiral structure with two spiral arms in the region of the outer ring. This suggests that NGC 7217’s central regions have suffered several starbursts. The outer ring is dominated by bright blue stars and is the location of most of the recent star formation in the galaxy. Although the galaxy is very gas poor for a spiral, this ring is also where we find the hydrogen gas to be concentrated. The galaxy is surrounded by an extensive, nearly circular luminous halo.

Other features this galaxy has are the presence of a number of stars rotating in the opposite direction around the galaxy’s center to most of them and two distinct stellar populations: one of intermediate age on its innermost regions and a younger, metal-poor on its outermost ones. An additional noteworthy feature is a symmetric ring of dust that surrounds the nucleus. Other dust lanes are seen mainly on the near side of the galaxy.

It has been suggested these features were caused by a merger with another galaxy and, in fact, computer simulations show that NGC 7217 could have been a large lenticular galaxy that merged with one or two smaller gas-rich ones, becoming the spiral galaxy we see today.

TRIFID NEBULA
I present to you, one of my most important works, an extremely difficult nebula to process, and I have never been so cold to get an image as it was in Munhoz - MG - -Brazil

high resolution: https://www.astrobin.com/full/364170/0/

Located approximately 5,000 light-years away, in the constellation Sagittarius.
A star-forming region in the plane of our galaxy, the object is an unusual combination, illustrates three different types of astronomical nebulae:
1) Red emission nebulae dominated by the light of hydrogen atoms.
2) Blue reflection nebulae produced by dust reflecting starlight
3) Dark nebulae, apparent "gaps" in the emission nebula, which cause trifurcarda appearance.

HELIX NEBULA
HELIX NEBULA

Planetary nebulae are actually the remains of stars that once looked a lot like our sun. These stars spend most of their lives turning hydrogen into helium in massive runaway nuclear fusion reactions in their cores. In fact, this process of fusion provides all the light and heat that we get from our sun. Our sun will blossom into a planetary nebula when it dies in about five billion years.

Have to comment on a few more pictures here...

Raul Villaverde, alcarreño, that's a great portrait of Andromeda. I like that smallish "dust ring" surrounded by a large, "soft" outer disk and halo composed mostly of old stars.

Delberson, that is a beautiful portrait of open cluster M23!

SUN SI, checkmates, I'm usually not so interested in pictures of the Moon and planets, but yours is fantastically striking!

SpookyAstro, that's a truly lovely picture of Comet 21P in Auriga! Look at all those well-known nebulas and clusters, and look at the brilliant color contrast between the comet and the stars, and look at that ginormous age-old "spaghettified" supernova remnant at lower right - Simeis 147, right?
