There are a lot of interesting astronomical events for photographers at the end of 2011, on October 21st we had the Orionids meteor shower, then Jupiter will be at opposition on the 28th. Venus starts to climb higher and produces some interesting conjunctions with the moon and mercury. Finally Mars also starts to climb higher in the sky and becomes brighter. The 2011 show ends on December with the 2011 Geminids meteor shower, always a reliable event even if the moon is bad for this year’s show.

I went out two nights, the 20th and 21st of October for the Orionids. The first night I tried from the coast of light-polluted Buenos Aires, I battled against winds of 40km/h and struggled all night long. The result: Zero meteors, I had hopes for a bright fireball to survive light pollution but it didn’t happen.

This is how the sky looked from my light-polluted spot:

Can you see Orion near the horizon? It’s difficult in the photo, easier with the naked eye.

Just before sunrise there was a nice conjunction between the Moon, Mars and Regulus. I took a shot from the same location before packing and going home:

For the night of the 21st I escaped to a rural area trying to win the battle against light pollution. It’s not easy when you live in a 10+ million people city like Buenos Aires, you need to drive more than 200km and even then you’ll find yourself near yet another city.

I drove to the County Observatory of Mercedes, 100km away from Buenos Aires. The observatory has nice rural skies, light pollution is only a problem in the direction of Buenos Aires to the East. Unfortunately Orion rises at the East so the battle was on again. The skies were much, much better and I managed to shoot two nice Orionid fireballs just before midnight.

The photo was selected as Amateur Astronomy Picture of the Day, thank you!

At 3am the moon emerged from the horizon and clouds rolled in, so it was time to go home. I took a shot of the cloudy nightscape with a fisheye lens to show how bright Jupiter was near opposition.

Jupiter shines at -2.7 magnitude you can compare it against the brightest star in the sky: Sirius at the top right of Orion. The Pleiades cluster is also visible in the photo. Even with the clouds you can see many more stars from this rural location than from a light polluted place. I will try to be in an even darker place for the Geminids, it just needs some weather help.

Finally a Stellarium capture of the Conjunction between Venus, Mercury and an ultra-thin moon just after sunset for October the 28th. If weather is good don’t miss it!

As usual I’ll be posting the photos as I process them in my Nightscapes Gallery at my website.

I have also added a new option for Matted and Mounted Metal Prints at a good price in the strange event of a visitor liking one of my photos 😉
