Astronomy Photographer of the Year: 2012 Edition

The Royal Observatory, Greenwich has just announced the winners, runner ups and highly commended entries for this year’s contest.

You can watch two of the judges discuss this years winners and runners up.

The entire list can be seen on the Royal Museum’s winners page here and in person at an exhibit. Below are those that I really liked – displayed with permission, of course.

Like me, Rogelio is a San Francisco Bay Area resident. Obviously Mr. Andreo has mad skills and dedication to astrophotography. See his portfolio for more work.

Lost in Yosemite [C_033706] Runner Up - Astronomy Photographer of the Year, 2012

It would seem that Rogelio and I are linked somehow. We both won in our categories in 2010, and we both were runner’s up in 2012. Above is my runner-up shot. Click the picture and read the story about the lost hikers we met on our night hike up Half Dome.

You can view a slides show of all the photos submitted to the contest here. Warning: There are a LOT of them – 688 in the over teen category (I’d call it adult, but that word seems to have a different connotation).

Astrophotography in the Big City

Getting back to the “good old days” when the Prince Georges County Maryland police paid a visit to my buddy and me… ah, nostalgia.  I will get around to the story in a moment, but first take a look at this:

Andromeda - Messier Object 31 and M110 [B_038508-22 DSS]

Photo 1: Andromeda (Messier Object 31) with M110

That is the Andromeda Galaxy, one of our nearest neighbor galaxies and it is visible with the naked eye in reasonably dark skies – or with binoculars in less friendly skies. Andromeda is almost directly overhead at midnight through the middle of October and directly overhead puts it in the best spot to photograph it (and the most pain in the neck to observe). Not surprisingly the Andromeda Galaxy is visible in the constellation Andromeda but the easiest way to find it is to look between the back of the Cassiopeia “W” and the large constellation Pegasus whose 4 dominant stars form a big square in the sky.

This image was taken from my backyard in San Jose, California WITHOUT a telescope but with a special apparatus called an Equatorial Mount. It’s actually not one photo, but more than two dozen. When I posted this image on Flickr many people asked me how I could get such detail without using a telescope. The answer is that Andromeda is very large. Here is a size comparison between Andromeda and the moon which may shock you:

The learning curve to do astrophotography is pretty steep, and if one is not careful or well informed it is easy to sink tens of thousands of dollars on astrophotography gear. My approach is much more modest. I am not a hard core astrophotographer. My relative newness to the field makes it easier for me to convey what good and bad choices I’ve made. If you want to learn what I’ve learned, I am offering a Webinar on “Astrophotography 101” that you may find well worth the cost of the class.

Back to my story…

As a teenager my friend and I checked out a telescope from our high school. The end of my street was a mostly vacant area and much darker than the surrounding suburbia. There was a nice flat sidewalk in front of a recently completed new home (which as far as we knew was unoccupied).  It was about 10:30 PM on a summer evening when we decided to set up to do some observing and attempt some photography. The problem was that the new home had a gas lamp burning in the front driveway. It was an annoyingly bright light. We discovered that we could turn off the lamp using a screwdriver on the gas valve. Problem one was now solved.  We also wanted to find a place to plug in our telescope drive motor so we could track the stars and take long exposures with our SLR camera. We knew the occupants of the other nearby house, but also could tell by the absence of light in any windows that they were asleep. We used our flashlights to search for exterior outlets to plug our extension cord into.

You can probably guess where this was going. More distant neighbors saw young males creeping about, turning off lights and searching about with flashlights. They justly reported suspicious activity to the police. The good news is that the police – after confirming with our parents – were pretty sure that we were doing what we told them we were doing: using a telescope! The fact that the telescope was there with a long extension cord running to it almost told the whole story.

These days I try to stick to places where my intentions are clear but even so I still sometimes find myself explaining to the rangers or the police what I’m up to.

And now I’d like to leave you with a stunning photograph made by a local astronomer: Erik Larsen:
