High Resolution Andromeda Galaxy – Messier 31
by Mike Hankey, under Galaxies
The Andromeda Galaxy has been one of my favorite pursuits since I started with astrophotography. It took me a while to figure out how to shoot it and each telescope you use reveals different things about the galaxy. I took this photo of Andromeda Friday night using a 14.5 inch RC and full format CCD. Andromeda is still too big to fit completely in this field of view, but I think we are getting about 75% of it. For reference, this is the same setup I used on the blue moon, so yes, Andromeda is bigger than the full moon in the night sky. Its just dimmer and harder to see with the naked eye. Imagine what it would be like to look up in the sky and see something like this.

Messier 100
by Mike Hankey, under Galaxies
Here’s a long exposure photograph of the spiral galaxy Messier 100. I collected the data for this picture over several nights in late February this year. Exposure times were 2 hours each of Red, Green and Blue color channels and 2 hours 40 minutes of Luminance. Total exposure time: 8 hours and 40 minutes.

Located roughly 55 million light years from Earth, Messier 100 is a grand design spiral galaxy estimated to be 160,000 light years wide.
Supernova in M95
by Mike Hankey, under Galaxies
An amateur astronomer discovered a supernova in the galaxy Messier 95 on March 16th, 2012. Two weeks later, the supernova continues to shine bright. Here’s a picture of M95 I took earlier this week. The supernova is the star to the lower right of the galaxy core. No one knows for sure when the supernova first erupted, but this object is not seen in pictures of the galaxy taken before March 20th.
Messier 95 is an estimated 38 million light years away from Earth, which means the star in this galaxy would have exploded over 38 million years ago. A supernova is the most powerful release of energy in the Universe. This supernova from a far distant galaxy outshines some of the other stars in the picture, which are all in our local Milkyway Galaxy. This gives you a relative idea about how bright and powerful supernovas are.
Messier 106
by Mike Hankey, under Galaxies
Last night was the first fully clear night we’ve had in weeks and with only a crescent moon popping out after 3:30, it was the perfect night for some astrophotography. I am still fine tuning aspects of my system and spent the first few hours of the night running tests, measuring various things and tweaking knobs in an effort to make improvements to polar alignment, PEC & collimation. I’ve gotten a new software suite from CCD Ware that really lets you fine tune these things. I didn’t want to waste the entire night tinkering so I moved on after making a little progress. Also on my list of procedural improvements, is mastering CCD Auto Pilot, which I’m getting better at, but still not entirely there. Last night I actually had a CCDAP5 session going great, but it lost the guide star after 2 frames and then lost the ability to plate solve. Not wanting to waste the night’s opportunity with tinkering, I rolled back to my non-automated procedures and started imaging the spiral galaxy Messier 106.
NGC 2175
by Mike Hankey, under Nebula
Here’s a recent astrophoto of NGC 2175, an open cluster centered in the Monkey Head Nebula. Found in target rich Orion, this nebula is a huge cloud of hydrogen gas covering an area larger than the full moon. The star cluster is visible to the aided eye and was first discovered before 1654 by Giovanni Batista Hodierna.

M51 – The Whirlpool Galaxy
by Mike Hankey, under Galaxies
Here’s a photo I took from my observatory of Messier 51, the famous Whirlpool Galaxy.
At an estimated 23 million light years away, M51 is one of the most famous galaxies in the sky and a popular target for amateur astronomers. M51 is an interacting, grand-design, spiral galaxy. Interacting means, the galaxy is merging with another galaxy resulting in a disturbance of both galaxies because the gravitational fields of each are ‘interacting’ with each other. Grand-design is a designation for a special type of spiral galaxy that has prominent, well defined continuous spiral arms. Less than 10% of all spiral galaxies are designated grand-design.
Earlier this year in June 2011, a super nova was discovered inside M51 bringing renewed attention to the galaxy. I don’t think the supernova is still visible in last night’s image. I did look to see if it was there though.
Happy New Year!

Spiral Galaxy – NGC 7331
by Mike Hankey, under Galaxies
I’ve been testing out a new scope the last month. I was finally able to get a pretty good shot out of it last night. Here’s a picture of the fantastic spiral galaxy, NGC 7331
NGC 7331 is 49 million light years away and approximately 30,000 light years across. It was discovered by Wilhelm Herschel in 1784 and is one of the brightest galaxies not cataloged by Messier.

M31 Astrophoto – The Great Andromeda Galaxy
by Mike Hankey, under Galaxies
Here’s my latest picture of the The Great Andromeda Galaxy. Also known as Messier 31, Andromeda is a spiral galaxy about 2.2 million light years away from Earth. In 964 a persian astronomer described the galaxy as a ‘small cloud’. When you look at Andromeda through a telescope, it looks like a smudge or a small cloud. Only with a camera and long exposure, does the galaxy’s true form take shape. The majestic spirals and bright center core reveal a universal grouping of over 1 trillion stars!
Compare the astrophoto above with a picture of the Andromeda Galaxy from about 1 year ago, or this photo of Andromeda from 18 months ago. Skills, equipment and 1 year’s experience make a big difference in picture quality!

Sunflower Galaxy – Lightbuckets
by Mike Hankey, under Galaxies
I’ve started looking into remote observatories recently. These are telescopes in far off dark places usually with optimal seeing conditions. The telescopes and cameras are all 100% computer automated and you can buy time on the scopes and do whatever you want. Here’s what I was able to do on my first run using LB0002 at Light Buckets Observatory.
Here’s a close up of the galaxy at full resolution:

NGC 891
by Mike Hankey, under Galaxies
Here’s my first attempt of photographing NGC 891, an edge-on spiral galaxy hidden about 30 million light years away in the constellation Andromeda.
I was surprised by how big the galaxy was especially since I was using a low powered telescope to view it. There are a couple of interesting things about this galaxy. 1) its edge-on which simply means what you think it means — we are looking directly at the edge or side of the galaxy. 2) Its an unbarred galaxy, which basically means there’s a big bulge in the middle of the galaxy. Since we are edge-on with the galaxy, we can see exactly how big that bulge is. These two factors working together along with the galaxy’s relative closeness and apparent size make NGC 891 a perfect astrophotography target.
During post processing, I had a few problems and some noise was introduced into the photo. I attribute this mostly to a bad set of flats. My flat field photo taking skills are one of the items on my short list for improvement. Problems aside, I’m still happy with the results and I will definitely be back to photograph this guy again.

M33 – Triangulum Galaxy
by Mike Hankey, under Galaxies
Approximately 3 million light years away in the constellation Triangulum is a spiral galaxy called The Triangulum Galaxy. Catalogued as Messier 33 or NGC 598,it is sometimes icalled the Pinwheel Galaxy, a nickname it shares with Messier 101. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, which includes the Milky Way Galaxy, the Andromeda Galaxy and about 30 other smaller galaxies.

Andromeda
by Mike Hankey, under Galaxies
Here’s a recent photo of the Andromeda Galaxy taken with a William Optics FLT98. At a mere 2.2 million light years away, Andromeda is the closest spiral galaxy to Earth and visible as a fuzzy dot in binoculars or a small telescope. On a dark night you can see it with your naked eye or a basic camera lens. Andromeda is estimated to have over 1 trillion stars making it 2-3 times larger than the Milkyway.

Sombrero Galaxy 2009
by Mike Hankey, under Galaxies
Here’s a recent shot of the Sombrero Galaxy from Dec 17th 2009. I’ve been wanting to shoot this guy again since getting my observatory setup but he hasn’t been available. I was up at 4:00 AM one night, ready to call it quits but saw the Sombrero on the goto menu. I extended the session an extra 15 minutes to capture 4×3 minute frames of this spectacular galaxy.
