Astrophotography of the Constellation Monoceros (The Unicorn)

0:00 Monoceros Since its stars are relatively dim, Monoceros is not a constellation that immediately draws your attention when you look up at the night sky. However, when I began "researching" what to observe in this constellation, I was surprised to discover many excellent targets. 0:25 NGC 2301 NGC 2301 is an open cluster of stars also known as “The Great Bird Cluster,” "Copeland's Golden Worm," and “Hagrid’s Dragon.” 0:38 Pakan’s 3 This is a nice asterism that resembles the number 3. 0:50 Rosette Nebula The Rosette Nebula is likely one of the most photographed nebulae in the night sky. It is an H II region, which is a vast cloud of ionized hydrogen gas often associated with star formation. The Satellite Cluster, also known as NGC 2244, is an open cluster of stars that formed within this immense cloud. I like the image I captured with the William Optics Cat 91, as you can clearly see the “elephant trunks,” and the Rosette's colors turned out nice. 1:28 Red Rectangle Nebula When I looked at other photographs of the Red Rectangle, I wasn’t sure if I could capture this object because it is so small. However, I believe the Celestron Edge HD 11” was up to the task. This is an interesting object to learn about—it is a protoplanetary nebula, a type of deep-sky object I had never read about before. As I understand it, a protoplanetary nebula is a precursor to a planetary nebula, a transition phase from a red giant to a planetary nebula. Interesting... I need to learn more about these. 1:36 Christmas Tree Cluster The Christmas Tree Cluster, also known as NGC 2264, is a young open cluster of stars. I was surprised to learn that these stars are thought to be only 1 to 5 million years old, which, in the grand scheme of things, isn't very old. The Cone Nebula lies at one end of the Christmas Tree Cluster, while the Fox Fur Nebula is at the other. 2:14 Hubble’s Variable Nebula While working on this project, this was my favorite image captured with the Celestron Edge HD 11”. The nebula is illuminated by the star R Monocerotis, and its brightness appears to change over time due to dust periodically blocking the star. 2:28 Cone Nebula The cone nebula is another H II region. An interesting object to look at. 2:45 Seagull Nebula There’s a lot happening here—many open clusters and reflection nebulae. It was interesting to learn about the star FN Canis Majoris, which is a runaway star—apparently ejected from the cluster of stars from which it formed. It has a high proper motion, causing a shock bow to form in this giant cloud of dust. 3:23 Dreyer’s Nebula Dreyer’s Nebula is a nice example of a blue reflection nebula. Most I've seen are white or red. 3:47 Sharpless 2-280 Here’s an image of another H II region that I found interesting. 4:03 Angel Nebula I spent the most time on this object—about three to four hours. It was quite dim, and getting the detail I wanted took a while. Anyway, I think the image turned out pretty well. The satellite trails through the middle of the image were particularly challenging to remove! I think I see the angel: there’s a head, two wings, and a robe… I’m pretty sure about this one. 4:42 Messier 50 Messier 50 is also known as the Heart-shaped Cluster. I think I see the heart… Maybe... Not so sure about this one. Clear skies!
