Messier 64 – The Black Eye Galaxy

The Black Eye Galaxy is also called Sleeping Beauty Galaxy or Evil Eye Galaxy. It is designated Messier 64, M 64, or NGC 4826. It is a relatively isolated spiral galaxy 17 million light-years away in the mildly northern constellation of Coma Berenice’s.

Messier 64 (M64) has a spectacular dark band of absorbing dust in front of the galaxy’s bright nucleus. This feature gives rise to its nicknames, the “Black Eye” or “Evil Eye” galaxy.

I photographed this galaxy for over 12 hours from my driveway in March 2025.

NGC 2903 – Beautiful Spiral Galaxy in Leo

NGC 2903 is a beautiful, barred spiral galaxy located in the constellation Leo, approximately 30 million light-years away from Earth. It is known for its dust lanes and blue regions of newly formed stars. The core region features “hot spots” that are actually newly formed globular clusters.

An odd fact about this galaxy is its dual identification. It is also cataloged as NGC 2905. This is a rare duplication of a New General Catalog entry.

Imaged with the RC8 scope at 1625mm, 071MC osc camera, and the Eq6r Pro mount.

Exploring NGC 3718: A Unique Distorted Spiral Galaxy

NGC 3718 is also known as ARP 214. It is a distorted spiral galaxy in the constellation Ursa Major. It is located about 59 Million Light Years away. Its distorted form is due to gravitational interaction with the other galaxy seen in this image, NGC 3729. This interaction happened at some point in the distant past. These are all part of a group of galaxies known as the Ursa Major Cluster.

One interesting footnote – below NGC 3718 you can see a small grouping of elongated shapes, very close together. While not shown very well in my image, this is a small group of 5 galaxies known as Hickson 56. These Galaxies are estimated to be about 400 Million Light Years away!

Exploring Messier 67: The Golden Eye Cluster

Messier 67 is also known as M67 or NGC 2682. It is sometimes called the King Cobra Cluster or the Golden Eye Cluster. It is an open cluster in the southern, equatorial half of Cancer. Estimates of its age range between 3.2 and 5 billion years. Distance estimates are likewise varied, but typically are 2,600 – 2,900 ly.

M67 is not the oldest known open cluster. Several Milky Way clusters are known to be older. However, they are farther than M 67. It is a paradigm study object in stellar evolution. It is well-populated and has negligible amounts of dust obscuration. All its stars are at the same distance and age, except for approximately 30 anomalous blue stragglers.

It has more than 100 stars similar to the Sun, and numerous red giants. The total star count has been estimated at well over 500.

Exploring the Little Beehive Cluster

Messier 41 (also known as M 41 or NGC 2287) is an open star cluster in the constellation Canis Major. It is sometimes called the Little Beehive Cluster. It slightly resembles a smaller version of the regular Beehive Cluster, M 44. It was discovered by Giovanni Batista Hodierna before 1654 and was perhaps known to Aristotle about 325 BC. It lies about four degrees almost exactly south of Sirius (the brightest star in the sky). Together, it forms a roughly equilateral triangle with Nu2 Canis Majoris to the west. All three figure in the same field in binoculars.

The cluster covers an area about the size of the full moon. It contains about 100 stars, including several red giants the brightest of which has spectral type K3, apparent magnitude 6.3 and is near the center, and some white dwarfs. The cluster is estimated to be moving away from us at 23.3 km/s. The diameter of the cluster is 25–26 light-years. It is estimated to be 190 million years old. Cluster properties and dynamics suggest a total life expectancy of 500 million years for this cluster. It will have disintegrated by then.

Peering into Sh2-308, the Dolphin Head Nebula

Sh 2-308 is commonly known as the Dolphin-Head Nebula. It is an H II region located near the center of the constellation Canis Major. The region is composed of ionized hydrogen. It is about 8 degrees south of Sirius, the brightest star in the night sky.

The nebula is bubble-like and surrounds a Wolf–Rayet star named EZ Canis Majoris. This star is in the brief, pre-supernova phase of its stellar evolution.

Sh2-308 sits at a declination of -23 degrees, which means it’s just above my tree tops to the south. Unobstructed for a couple of hours per night it takes a while to gather significant data. With weather, life and the moon impacts this will be all I get of it this year.

Peering into the Needle Galaxy in Coma Berenices

NGC 4565 / Caldwell 38 is an edge-on spiral galaxy. It is about 30 to 50 million light-years away in the constellation Coma Berenices. It lies close to the North Galactic Pole and has a visual magnitude of approximately 10. It is known as the Needle Galaxy for its narrow profile.

This image consists of 169 3 minute exposures captured over two nights in Feb 2025. A GSO RC8 paired with the ASI071MC Pro was used atop a SW Eq6r Pro.

Exploring M 53/NGC 5053 – a globular cluster pair in Coma Berenices

A globular star Cluster (M 53) is located in Coma Berenices. It is one of the most distant globular clusters, situated 59k ly from earth. Globular star clusters are found in the galactic plane of our Milky Way Galaxy. They cause the massive glow of our core.

Astrobin link for this image.

M 53 appears to be connected to the nearby globular cluster NGC 5053 by a tidal bridge-like structure. To the right is a low mass globular cluster cataloged as NGC 5053 – 56k ly from earth. This is a metal-poor cluster. This means the stars have a low abundance of elements other than hydrogen and helium. Astronomers term this “metallicity”. As recently as 1995, it was considered the most metal-poor globular cluster in the Milky Way.

The chemical abundances of the stars in NGC 5053 are similar to those in the dwarf galaxy. Specifically, they resemble the Sagittarius Dwarf Spheroidal Galaxy. They differ from those in the Milky Way halo. The kinematics of the globular cluster support this idea. This suggests that NGC 5053 may have been stripped from the dwarf galaxy.

Exploring M 105 & friends in Leo

This image centers on a three galaxies in the Leo Constellation.

They are NGC 3384, M 105, and NGC 3389. A lesser player to the left is IC 642, it’s tiny. Annotated astrobin link.

NGC 3384 is a lenticular galaxy in the constellation Leo, about 35 million light-years away.

Messier 105 or M 105, also known as NGC 3379, is an elliptical galaxy 36.6 million light-years away in the equatorial constellation of Leo. It is the biggest elliptical galaxy in the Messier catalogue that is not in the Virgo cluster.

NGC 3389, a spiral galaxy in Leo. While not large I did manage to get some detail of this galaxy.

Sh2-247 – A dust ball in Gemini

Sh2-247 is a round diffused nebula positioned at the western edge of Gemini near a boundary on Orion. It is part of the Gemini OB1 molecular cloud complex and is located near the boundary with Orion. Admittedly, it’s not very exciting to look at.

It’s located near the Monkey Head Nebula as well as the Jellyfish Nebula.

Imaged over three nights, this image consists of 161 5-minute exposures. These were taken with a GSO RC8 telescope at 1625mm f/8. It is paired with a ZWO ASI071MC camera atop a Skywatcher Eq6r Pro mount. Acquisition session management with Astro Photography Tool (APT 4.60).
