The Rosette Nebula (NGC2237) is a cloud of gas and dust, about 130 light years in diameter, lying approximately 5000 light years from our Solar System, in the direction of the constellation of Monoceros. The mass of the nebula is estimated at 10 thousand Solar masses, even though it is just a small part of a much larger region of gas and dust spanning the entire constellation. The Rosette would appear Continue reading The Rosette Nebula – who knew so much gas and dust could be so gorgeous! I just added a new page to my site. The link is at the top and is called Astro Photography. To see the more detailed descriptions on each of the photos, click on the Astro Photography category in the left hand column. If you enjoy seeing Dave’s photos, please take the time to leave a comment on the new Astro Photography page. Enjoy! The Orion Nebula complex (M42, NGC 1976) is the Continue reading Astro Photography: M42 – the Orion Nebula This is a wide field photo of the area around the star Alnitak, the easternmost star that forms the belt in the bright winter constellation of Orion the Hunter. It contains the Flame Nebula and the Horsehead Nebula, both of which I took close up views of last winter. Photo by Dave Chaton
The Fireworks Galaxy. Photo by Dave Chaton This is Dave’s newest photo – started a month ago on October 28th, and the most recent photo taken last night! It was taken over a period of just over a month (due to cloudy skies and moon filled nights). It is a stack of twenty 30-minute exposures for a total of ten hours. The Fireworks Galaxy (NGC 6946) is a faint but relatively close by Continue reading Astro Photography: The Fireworks Galaxy (NGC 6946) NGC 7332 Spiral Galaxy. Photo by David Chaton, taken at the South Side of the Sky Observatory. Spiral galaxy NGC 7331, in Pegasus, can be seen with small telescopes under dark skies as a faint fuzzy spot. The galaxy is similar in size and structure to the galaxy we inhabit, and is often referred to as the Milky Way’s twin. This galaxy is 49 million light years away (and perhaps 30,000 light Continue reading Astro Photography: Spiral Galaxy NGC 7331 Photo by Dave Chaton. This photo was taken last Saturday. The Triangulum Galaxy (Messier object 33) is a spiral galaxy at approximately 3 million light years (ly) distance in the constellation Triangulum.With a diameter of about 50,000 light years, the Triangulum galaxy is the third largest member of the local group of galaxies which also contains the Milky Way Galaxy and the Andromeda Galaxy, and it may be a gravitationally bound companion of the Continue reading Astro photography: The Triangulum Galaxy Have you checked out Jupiter? It’s really bright right now! Stellarium is a really cool program that you can use to view a simulation of the night sky in realtime – basically your own personal desktop planetarium! This means that the skies will look exactly like what you see with your eyes, binoculars or a small telescope. You can set it to real time, reverse or go forward and go even faster or slower! It’s easy to zoom in on objects as well as Continue reading Would you like to have the night sky on your computer? M31: Andromeda Galaxy. Photo by Dave Chaton. The Andromeda Galaxy is a spiral galaxy approximately 2,500,000 light-years away] in the constellation Andromeda. It is also known as Messier 31, M31, or NGC 224, and is often referred to as the Great Andromeda Nebula in older texts. Andromeda is the nearest spiral galaxy to our own, the Milky Way, but not the closest galaxy overall. As it is visible as a faint smudge on Continue reading Another spiral galaxy: Andromeda |
