M51 – The Whirlpool Galaxy

Mike Hankey — Thu, 29 Dec 2011 21:18:12 +0000

Here’s a photo I took from my observatory of Messier 51, the famous Whirlpool Galaxy.

M51 - The Whirlpool Galaxy - December 28th, 2011

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!

Galaxy NGC 891

Here’s a photo of the Galaxy NGC 891. This is the first image I have taken with my new system where all things were working perfectly: mount, scope, focusing, temperature & software. I am especially excited about figuring out the automation software because I literally slept through this job!

Spiral Galaxy – NGC 7331

Mike Hankey — Sat, 19 Nov 2011 21:04:28 +0000

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

Spiral Galaxy NGC 7331 - November 18th, 2011

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

Mike Hankey — Wed, 28 Sep 2011 13:05:36 +0000

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

Mike Hankey — Sun, 20 Mar 2011 20:50:44 +0000

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.

NGC 891

Mike Hankey — Tue, 08 Feb 2011 02:19:39 +0000

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

Mike Hankey — Wed, 10 Nov 2010 03:58:28 +0000

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

Mike Hankey — Mon, 13 Sep 2010 04:23:57 +0000

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.

M88

Mike Hankey — Tue, 04 May 2010 02:48:14 +0000

Here’s a wide field shot of the galaxy M88, one of 15 Messier galaxies in Virgo’s cluster of galaxies. Approximately 47 million miles away from Earth, M88 is a spiral galaxy with a highly elliptical orbit. This orbit will lead M88 to the core of the galaxy cluster in another 200-300 million years. There are several other galaxies visible in this picture, including M91 at the top center of the picture.
