Imaging Projects

In this blog, I will share the results of all of my imaging projects. The newest will be at the top and the oldest will be further down the stack. Going back in time here is interesting - some of my early stuff was pretty rough - but I did not see it that way at the time - I was thrilled to get anything back that looked like an image! Hopefully, you will see how my work has progressed with time!

Messier 8 - The Lagoon Nebula

Messier 8, also known as the Lagoon Nebula, is a giant interstellar cloud located in the constellation Sagittarius and is 4000-6000 light-years away. This is a rich star-forming region - in fact, it is one of the two such regions that are bright enough to be seen with the naked eye under dark skies.

This is my second effort shooting this target.

Arp 271 - Interacting Galaxies: NGC 5426 & NGC 5427

Arp 271 consists of two distant spiral galaxies, NGC 5426 & NGC 5427) that are interacting and gravitationally linked. The galaxies are located a whopping 130 Million light-years from earth, in the cancellation of Viro. Both galaxies are of a similar size and have been interacting for millions of years, and they will continue to for millions more. It is not known whether they will collide or not. But we do know that the mutual gravitational attraction has created "bridges" of stars, gas, and dust between them.

The Arp designation refers to "The Atlas of Peculiar Galaxies," a catalog of peculiar galaxies produced by Halton Arp in 1966.

Messier 17 - The Omega Nebula

M17 is one of those objects that has collected a lot of common names over the years. Most often known as the Omega Nebula, it has also been called the Swan, Horseshoe, and Check-Mark Nebula.

As you look towards the southern sky during summer, you are actually looking to a very bright portion of our own Milky Way Galaxy, and M17 is part of that region. The Omega Nebula is a large region of Hydrogen II Gas located in the constellation Sagittarius. It is between 5000 and 6000 light-years from earth and has a diameter of about 15 light-years.

NGC 4631: The Whale Galaxy and NGC 4656: The Hockey Stick

NGC 4631(The Whale) and NGC 4656 ((The Hockey Stick) are fascinating pair of galaxies. Both galaxies fit in the same frame, and this creates an interesting composition.

NGC 4631 is the larger and brighter of the two. Located about 30 Million light-years from Earth, this galaxy has a wedge-shaped form that resembles a whale, thus - its name. In addition, NGC 4631 has a nearby dwarf elliptical galaxy, NGC 4627, as a companion.

NGC 4656, the Hockey Stick - also known as the Crowbar Galaxy, is a highly warped barred-spiral galaxy. Its distinctive shape is due to a *recent* gravitational interaction with NGC 4631. T

NGC 5981, NGC 5982, & NGC 5985: The Draco Triplet

The Draco Group of Galaxies are a string of three primary galaxies that can be seen in a common field of view in the constellation Draco. The largest and roundest one seen at the bottom of the frame is NGC 5985. This has a barred spiral structure, and the arms are clearly visible in this shot. NGC 5981 can be seen at the top of the frame. This is also a barred spiral galaxy, but it is seen almost edge-on. The galaxy in the center is NGC 5982. It is an elliptical galaxy - which is typically seen as nebulous without any obvious structure. These galaxies are approximately 100 Million light-years from earth.

Messier 20 - The Trifid Nebula

The first imaging attempt on Messier 20, commonly known as the Trifid Nebula, is a Hydrogen II region in Sagittarius located about 5000 light-years from earth. The name "Trifid" means "divided into three lobes," This describes the impression when seen visually in a Telescope. This object combines an open cluster of stars, an emission nebula (the red portion), and a reflection nebula (the blue portion), making it a rich target for astrophotography. The dark lanes are concentrations of dust and gas that form nurseries for the formation of new stars

Messier 13 - The Great Globular Cluster

Messier 13 - The Great Hercules Cluster is about 22-25 thousand light-years away and is about 145 light-years in diameter. This consists of a ball of several hundred stars packed together. This and other globular clusters are distributed around the outer plane of the galaxy and seem to be made of ancient stars.

This is the second time I shot this target with the WO132mm Platform. The first was in 2019.

Messier 106 - A Galaxy in Canes Venatici

M106, also known as NGC 7353, is a galaxy in the constellation Canes Venatici (The Hunting Dogs), which is located between 22 and 25 million light-years away. M106 is a massive galaxy with a very active core region that is home to a supermassive black hole. The core is extremely bright relative to the galaxy and in my image, the core is a little over-saturated because of this.

Messier 63 - The Sunflower Galaxy - 2020 version

Messier 63, also known as NGC 5055, M63 is located in the constellation Canes Venatici (The Hunting Dogs) and has the common name of the Sunflower Galaxy. M63 is a spiral form galaxy with loosely wound arms with relatively poor definition in visible light. The arms are visible when observed by radio at the 21-cm Hydrogen line wavelengths. Located about 29 million light-years from Earth, M63 is a part of the M51 Group, which includes the famous Whirlpool Galaxy.

This is the second project with this target - captured on the William Optics 132mm Platform.

Messier 64 - The Black-Eye Galaxy

Messier 64 is also known as the Sleeping Beauty Galaxy or the Evil Eye Galaxy and is designated as M64, or NGC 4826. It is located 17 million light-years away in the northern constellation of Coma Berenices. It measures about 54,000 light-years in diameter, making it about half the size of our own Milky Way. It has a swirling central disk of dark dust, which gives it a unique look that inspires its name.

This was captured on the William Optics 132mm Platform.

Messier 45: The Pleiades and Venus - A Conjunction

Venus approaches M45 - the Pleiades star cluster. It's not very often that you can see a planet so close to a well-known star cluster, and since it was marginally clear last night, I decided to try capturing it. This was shot with my Sony A7iii shooting with the Sony 100mm-400mm GM Zoom with the 1.4 Extender on it. The entire rig was mounted on a heavy carbon fiber tripod. This is 30 x 1-second exposure at F/8, stacked in Deepsky Stacker and processed with Pixinsight and Photoshop.

Messier 45 - The Pleiades Star Cluster

Messier 45, better known as the Pleides Star cluster or the Seven Sisters, is a large star group easily seen with the naked eye in the constellation Taurus - the Bull. Wow, Rochester weather in the late fall really sucks. It has been almost 9 weeks since I have had a clear night! Finally, we had a nice clear sky last evening, and the temperature was not too brutal - about 37 degrees F. My first shot of the night was M45, the Pleiades star cluster. Also known as the Seven Sisters, this open cluster is visible to the naked eye in the constellation Taurus. The framing is a bit tight here for my scope focal length, but I was just able to fit them into the field of view. These are a grouping of middle-aged blue stars, and on longer exposures, you can see local dust clouds illuminated by these blue stars. This was the result of 20 three-minute exposures.
