Observing Orion
In the last few weeks I observed a few interesting objects in Orion. I started in januari with Collinder 70, Orions Belt. Last week I had a look at Collinder 69 and Collinder 72, one of Steven James O'Meara's hidden treasures. Today I added another three wonderful objects to my sketchbook: Rigel, Betelgeuse and Collinder 65.

Rigel was observed with the 12 inch dobson. The double star did not show itself as a double initially, due to a lot of turbulence in the tube (the scope was just outside for a few minutes. However, after switching on the fan, the weaker B companion popped into view, just like that. The image was stable right from the moment the fan started to make a laminar flow in the 12-inch tube. Amazing. Betelgeuse was also observed with the twelve inch, and the deep orange color was simply overwhelming, especially at lowest power. However, in the 85mm Zeiss, the color looked even much deeper than in the 12-inch.

Collinder 65 is a large open cluster, which actually belongs to Taurus, but lies on the Orion-Taurus border. I observed and sketched this large open cluster (3.3 degrees) using the Skywindow and the 8x42 Orion binoculars, field of view 8.2 degrees. Until a few days ago I didn't know this cluster was actually there, but when scanning the area between Collinder 69 and Messier 1, you cannot miss it. You immediately will recognize it as a cluster.

In the next few weeks I hope to publish my observing reports and sketches on On the map below you can see where the objects I observed can be found.
