M51

After shooting the supernova in M82, I pointed the telescope at an object I have been trying to shoot many times. M51, the Whirlpool galaxy. But either it was too small in the scope, or the exposure was too short. But on monday, I decided to try exposing the rest of the night on this magnificent object. We see it almost straight down, and the spiral structure is clearly visible. It is obvious that I could probably spend more time enhancing this beautiful object. And I could probably spend some more time exposing. But for a first try both at a successful exposure, and at a reasonable size, I am happy.

Supernova SN2014J

Finally, after weeks of overcast and bad weather, the skies cleared last night, and I was able to capture an image of the famous supernova in M82. In the image below, it is framed with its trusty companion M81. I love this pair. One of my favorites. And now with an extra feature. A new star! Only that this is putting on its final show.
