Moon and Sirius B – March 24, 2015

Scroll down to content

Despite some rather poor seeing conditions (3/10), with the Moon at only 30 degrees above horizon, I did get out for a brief imaging session together with Claudiu.

The designated scope for this session was again the 355mm Newtonian, at F/11 coupled with the DMK21 camera and a Baader Red filter.

The following images show some well-known lunar formations but under a less often observed illumination.

Also, I’ve managed to capture again the elusive component B of Sirius, a second time. The first time I had far better seeing conditions, but still, in the following images Sirius B is well resolved.

  1. Glad to see the little B companion finally showing up in these images. The 355 really made an impression on me in the last few weeks (Jupiter/Moon/Nebula), but still deserves far better seeing conditions to perform. It’s like a beast in a cage.. roaring πŸ™‚

    1. Yep, it really is a good comparison the one you’ve made! But for a beast, lets say a large cat, to be free, it must go in the jungle. This is what my 355 should do also: go to Barbados πŸ™‚ With me included πŸ˜‰
