We were blessed to be able to go on a quick two week trip down south from New England to see some of my wife’s family and some of mine. Unfortunately, even though I brought my entire astrophotography rig down, I did not very many clear nights. The one good night I did get, I was not in a good place to setup my entire rig (could not see Polaris to polar align, a lot of trees, etc). However, I still was able to get out and do some experimenting by taking one second exposures with the Canon EOS Ra attached to the TPO 180 Ultrawide Astrophotography Lens. One of the targets I choose to hit up was Betelgeuse. Late last year I promised a friend that if I ever had a chance to set my camera to Betelgeuse i would and I hate to admit that I simply never took the time to do so, until now.
Above is Betelgeuse with some surrounding sky with no annotation, annotated and in negative. I really had a good time experimenting while getting this shot. This data was collected in Griffin, GA.
