2009 Southern Skies Fiesta & Tamarindo Coast
I join the early morning wildlife walk at 6AM since I’m still up from the previous night’s observing. The horses are in the field as the sun rises, and we see a big iguana along with some birds as the Howler monkeys look down on us from the trees. Time for breakfast and a nap.
I go on the boat trip to the mangrove swamp, showing up at 2PM down at the dock with my Canon 50D and the 17-85 zoom lens. However after we spot our first birds (Pelicans), I wish I had brought the 70-200 zoom instead. The birds we see are pretty close, but the extra reach of the longer zoom lens would have given me better image scale. We follow a similar route as last year, seeing lots of birds busy catching fish, spoonbills in the trees, and a Pelican colony at close range. It is cooler than I remember the boat trip from last year, and the water isn’t as rough on the return trip. After we return, I have a swim in the pool before going for dinner – very refreshing!
This evening I look at M42 Orion Nebula through a 15” Obsession Dobsonian telescope one of our group has brought with them on the trip. Our astronomy leader Gary thinks this telescope holds the record as the largest aperture telescope brought on the tour so far. All I can say is the views through it are superb. The breathtaking view of M42 reveals the beautiful blue colour of the reflection nebula – a first time for me with any scope I’ve used on this showpiece object. We also have a look at the Sombrero Galaxy, where the dust lane is evident, and Comet Lulin’s spectacular dust tail.
Later in the evening, I do some astrophotography using my dSLR mounted on an Astrotrac tracking mount on a tripod. It works very well, but my choice of targets: the emission nebulae in Vela turns out to be underwhelming. Later I change targets to a widefield of M42 Orion Nebula, including the Flame Nebula and the Horsehead Nebula, and am rewarded with a breathtaking resultant image.
After midnight, I turn my camera to Comet Lulin and have yet more success. I take relatively few frames to capture the comet’s tail, but stacking 62 light frames referenced to the comet head shows just how fast this comet is moving through the cosmos indicated by the star trails. I go to bed tired but happy after a busy night of observing and photographing the night sky.
