RASC - Saskatoon Centre New Members Night

After a far-too long absence, mainly due to such horrible weather for most of the past few months, I finally have a new post. At a local meeting of our astronomy club (RASC - Saskatoon Centre), I had suggested we have a new members night as a way to get new people out and have some experienced astronomers share their knowledge. As a new(er) member myself, I thought this would be a good idea since there is much I need to learn about astronomy in general.

We met at the University of Saskatchewan Observatory on June 17th. It was organized mainly by Patricia G (thanks for that). Local members Richard Huziak and Mike Clancy spoke to us. Rick talked about choosing telescopes, eyepieces and binoculars, etc. while Mike spoke about the Explore the Universe certificate program offered by the RASC. There were about 10 people who were out to listen to the talks, which were both enjoyable, informative and entertaining. Thanks to Rick and Mike for speaking.

Below are some images of the talk itself and of the observatory. The observatory has been a fixture on the U of S campus for many years. It houses a 6-inch telescope. For more info on the observatory, visit this link.

Northern Lights In the North (Sort Of)

I had the chance to finally capture some Northern Lights (Aurora Borealis) on April 5, 2010. I was out with my good friend Bob of Blackholes and Astrostuff and went just outside the city limits to catch them. They didn't last too long, so we had to work fast. For my first time photographing them, I was pleasantly surprised with the results. At first, I was skeptical about how the shots would turn out, because I was using my Nikon D90, which is notoriously bad for the level of noise it introduces into night shots. But, with a little tweaking using my software, I was able to get the shots looking half-decent.

Aurora's are basically the emission of photons in Earth's upper atmosphere. For a more detailed description, please click here. I can try to explain it but I'm not a science-type guy and therefore wouldn't do it justice. Also, in the title, I have sort of in brackets. The reason for that is because while we may be fairly north of some places that can see the Northern Lights, we are not far enough to see the amazing ones that are seen in the Arctic. They still look pretty awesome.

And a special thanks to Planetaryman (my Dad) for being my newest follower.

Enjoy the photos. And hopefully, Blogger won't butcher them too much this time.

Earth Hour In Saskatoon

The theme this year at the Centre Mall in Saskatoon for Earth Hour is "Go Celestial". Saturday, March 27, 8:30-9:30pm at the entrance by Tony Tomas is the place to be during Earth Hour. Here is a link to the Earth Hour Canada site.

Earth Hour was started in 2007 in Sydney, Australia when over 2 million homes turned off their lights for one hour to bring awareness to climate change. In 2008, over 50 million people in 35 countries participated and in 2009, more than 88 countries took part. 2010 is sure to be even bigger.

Last year in Saskatoon, there was a large line-up of people at the Centre Mall, so this year only promises to be bigger (weather providing of course). I plan on being there for this event, as does Bob of Blackholes and Astrostuff. The Royal Astronomical Society of Canada Saskatoon Centre will be setup as well with telescopes set up. But Bob cautions everyone to maybe be there about 30 mins ahead of time to setup your scopes before viewing starts.

The first link below is to the page on the mall site about the event. It's the second from the bottom. The last link is the flyer the mall has put together for this event.

Hope to see you out

Zodiacal Lights (and Casino Lights)

On March 6, 2010, I went out with Bob of Blackholes and Astrostuff to photograph the Zodiacal Lights. Zodiacal light is caused by sunlight reflecting off of dust particles in the solar system known as cosmic dust, known as the interplanetary dust cloud. It usually appears as a triangle-shaped column of light in the western sky in the spring just after the evening twilight has disappeared, or in autumn just before morning twilight appears.


The following picture is one that was taken the same night as the ones above. It is of our local Dakota Dunes Casino lights shining into the sky causing light pollution. Unfortunately, the casino operators have no respect for astronomy nor care that the light pollution is a problem. Thus, the lights persist night after night. Orion constellation is in the center, The Hyades are up and to the right of that and the Pleiades are in the top right corner.

And Now For Something Completely Different

I was in Lethbridge, AB this past week and noticed that the Moon was up during the day. There is a neat looking bridge there called the High Level Bridge. It is used by trains to cross a large valley. It is the largest of it's kind in the world. I've been wanting to photograph it for some time now and finally had the chance. I went out on a day when there was little cloud cover and the Moon was visible during the day.

It also gave me a good chance to finally use my Canon 40D. I will be posting pictures taken with the Canon soon, but for now, here are the photos taken with my Nikon D90.

Sundog Days of Winter

"Dazzle mine eyes, or do I see three suns?"

Shakespeare - Henry VI, Part 3

The word sun dog (or sundog) originates from the Greek word parēlion, meaning "beside the sun". The scientific name is parhelion, plural parhelia. It's essentially a phenomenon in the atmosphere formed by plate shaped hexagonal ice crystals (in high and cold cirrus clouds) that create bright spots of light, often a luminous ring (or halo), on either side of the Sun. The ice crystals are called diamond dust and drift in the air at a low level. Sundogs orrur when the Sun is at a 45 degree angle and is at its lowest point. Sundogs may appear as a colored patch of light, typically displaying the colors of the rainbow (red closest to the Sun, with orange then blue farthest out) to the left or right of the sun at the same distance above the horizon as the sun. They can be seen anywhere in the world during any season, but they are not always obvious or bright. Here in Canada, they are most prevalent during the winter months when the air is coldest and more ice crystals are in the sky.

Below is the first-ever photo of a sundog taken be myself in January 2010.

Perigee Moon and Mars

Finally, I've been able to put up a new post after a two month hiatus. By hiatus I mean cloudy, snowy and cold weather interfering with my picture taking and observing with the telescope. However, I am happy to report that I was able to snap the perigee Moon last night and Mars. It was the first time I've ever seen Mars through the lens of my camera. I'm hoping it will warm up a little so I can observe it through my scope.

Cool November Nights

Even though October was a complete waste as far as the night sky went where I live, I was finally able to get out with my telescope tonight. Even though it's only 4.5" in diameter, I was able to see some things I never have before. It was quite exciting. And this was in-the-city viewing, with all of the light pollution we have too. So, I was able to see the Andromeda Galaxy (M31), the Orion Nebula (M42 and 43), Hyades (in Taurus) which was really awesome, the double cluster in Perseus consisting of NGC 869 and NGC 844 (which was awesome), and a few others. I did try to photograph them, but to no avail. So, now for some info on what I was able to see.

The Andromeda Galaxy
This particular galaxy is probably the most famous in the night sky. It is bright enough, at magnitude 4.4, to be seen with the naked eye. It is also known as M31 (or Messier 31) and NGC 224. This galaxy is like our own Milky Way in that it is a spiral galaxy believed to be similar in mass. It is located approximately 2,500,000 light years away and is found at Right ascension 00h 42m 44.3s, Declination +41° 16′ 9″[1].

The Orion Nebula
This nebula is also known as M42 or NGC 1976. It is referred to as a diffuse nebula (and contains mostly ionized hydrogen) and is located just below Orion's Belt at Right ascension 05h 35m 17.3s, Declination -05° 23′ 28″. At an apparent magnitude of +3.0, it is visible to the naked eye and is approximately 1,344 light years away. The Nebula is part of a much larger nebula known as the Orion Molecular Cloud Complex. This Complex extends throughout the constellation of Orion and includes Barnard's Loop, the Horsehead Nebula, M43, M78 and the Flame Nebula. Stars are forming throughout the Orion Nebula, and due to this heat-intensive process the region is particularly prominent in the infrared.

The Hyades
I have never seen this before tonight. I thought it was really neat. I found it by accident. I had been looking for Orion and the Pleiades. Almost in between them, I could see a fuzzy patch, so I pointed my scope at it and saw this open cluster. It is classed as an open cluster because the stars are not as tightly bound by gravity as they are in a globular cluster. It consists of a roughly spherical group of 300 to 400 stars that share the same age, place of origin, chemical content, and motion through space. Hyades is approximately 151 light years away and can be found at Right ascension 04h 27m, Declination +15° 52′. The Hyades Cluster, at apparent magnitude 0.5, lies in the constellation Taurus, where its brightest stars form a rough "V" shape along with the still brighter red giant Aldebaran. Contrary to how it appears, Aldebaran is completely unrelated to the Hyades, as it is located much closer to Earth and merely happens to lie along the same line of sight.

Perseus Double Cluster
These two open clusters are known as NGC 884 and NGC 869 (or more commonly known as the Double Cluster). They are visible to the naked eye and lie in the constellation Perseus, below Cassiopeia. NGC 884 is approximately 7600 light years away with NGC 869 being about 6800 light years away. They can be found at Right ascension 2h 20m, Declination 57° 08′. In the photo below, NGC 884 is the on the left and NGC 869 on the right. It is said they have blueshifted as well, which is a method of determining their distance using light wavelengths, etc. They are traveling toward Earth at approximately 22km/s.

October Night Sky Events

October is a good month for observing. The sky is darker earlier, it's still not terribly cold outside (we hope), and there are different objects to see. For example, the Orion constellation is up and with it, the Orionid meteor shower.

On Oct. 8 at about 6 a.m., Venus should be shining brightly near the eastern horizon. Below that, depending where you are, you might spot Mercury and Saturn. By Oct. 13, at about 6:30 a.m., Saturn will have moved to the upper left of Venus. On Oct. 16, in the eastern sky, just before dawn, there should be a conjunction with the crescent Moon and Venus and Saturn. Then on Oct. 26 or 27, the Moon and Jupiter should be in conjunction at just three degrees apart.

A major event this month is the lunar landing of the LCROSS lunar rover. I believe it should be visible if you have a 10" or larger telescope. There is a countdown clock on the right side of this page.

Another important event this month is the RASC Saskatoon Centre open house at the Sleaford dark site. It is located about 65 kms east of Saskatoon and offers great celestial viewing. This event will be held on Friday, Oct. 23 and Saturday, Oct. 24. There will be a convoy of cars leaving from the east end of the Saskatoon Field House parking lot at 7 p.m. on both nights. The Sleaford site is operated jointly by the RASC Saskatoon Centre and the U of S Department of Physics and Engineering Physics. RASC club members will set up their own telescopes, in addition to the U of S telescopes that are setup there. For more information call 966-6429. Make sure to take warm, weather appropriate clothing.

Additional viewing events for October:

Oct. 7 - Moon 0.1 deg N of Pleiades (M45)
Oct. 8 - Draconid meteors peak; Mercury 0.3 deg S of Saturn
Oct. 10 - Moon 1.2 deg N of M35 (open star cluster in Gemini)
Oct. 12 - Occultation of the Moon and Mars
Oct. 13 - Moon at perigee (369067 kms)
Oct. 15 - Zodiacal light visible in eastern sky before morning twilight for the next two weeks
Oct. 21 - Orionid meteors peak
Oct. 25 - Moon at apogee (404166 kms)

And The Fight Is On...

Well, I've done it. I've bought a Canon camera. After much deliberating, I have taken the plunge back to Canon. I sold my Nikon D80 and bought a Canon 40D. I have kept my Nikon D90 however. I have an 18-55mm image stabilization lens for the D90 and I've ordered the same size lens for the 40D. Both will have batter grips, and remote shutter release cables.

I've heard nothing but great things about the 40D. My friend Bob, of Blackholes and Astrostuff has a 40D. I've always loved how his photos turn out so much more full of color than mine. The major difference is in the sensors on the camera. The Nikon is not an ideal camera for night photography, in my opinion. It introduces too much noise and red color into the photos. The Canons is rated far superior for night photography than the Nikons.

One thing I noticed at the Cypress Hills Star Party (SSSP 2009) in August, is that everyone had a Canon DSLR for night shooting. I had the chance to meet Alan Dyer while there and bought his book (that was co-written by Terrence Dickinson), The Backyard Astronomer's Guide. Even in that book they recommend strongly that Canon is the only way to go for night photography. So, how could I pass up the chance to improve my night shooting of the stars by not getting this camera? Truth is that I couldn't.

I haven't had a chance to use the 40D yet, due to the weather, but hopefully soon. I'll also be ordering the necessary adapters to attach the Canon to a telescope, similar to the set up for my Nikon. As soon as I have some results, I'll post them. For now, I have a picture of the Nikon D80, Canon 40D and Nikon D90, respectively, so you can see how they all look.
