An incredibly cold and calm night. Some light haze from time to time. Transparency not great. Milky Way visible.


The Great Orion Nebula

I spent most of the evening gathering images of the Great Orion Nebula. This was my first attempt at this target with the Canon 6D. I found 20s exposures at ISO1600 gave promising results although I did experiment with shorter exposures and lower ISO to gather additional data to bring out detail in the brighter regions. I didn't do a great job of capturing darks.

Winter Milky Way Open Clusters

Whilst imaging the Orion Nebula I used my binoculars to scan along the winter Milky Way, taking in several of the more distinctive open star clusters along the way. I started with M35 in Gemini, moved up to the three amigos in Auriga (M36, M37 and M37) before continuing up via the Double Cluster to the Cassiopeia region.

The Pleiades

I finally swept over to the Pleiades - always an excellent view in binoculars. The cluster sits nicely in the field of view with crisp stars.
