Markarian 6
A few weeks ago I observed a very small and bright open cluster on the edge of the Heart Nebula in Cassiopeia, Markarian 6. The cluster looks more like a small asterism than a real open cluster, as you can see on the sketch below. Follow this link to my other website, starobserver.eu, for the complete observing report, finderchart, and a beautiful image of the heart-nebula by Dominique Suys (thanks Dominique for granting me permission to use your image for my report!)

The belt of Orion
At the end of 2010 I added three new objects to my StarObserver website. The two open clusters: NGC 129 and Stephenson 1 and a very interesting triple star, 40 Eridani. Just click on the links to have a look at some very interesting facts and stories on these fascinating objects.

Last week I made my first ever sketch of an OB Association, Orion OB1b, also know as Collinder 70, or just as The Belt of Orion. This large group of stars is a perfect binoculars. It is centred on the three bright belt-stars of Orion, and offers stunning views. I observed them with my 8x42 (8.2 degrees FOV), 12x60 (5.6 degrees FOV) and the 15x80 (3.5 degrees FOV). In the end I used the SkyWindow and my 15x80 to make this sketch. In time an article about this wonderfull object will be added to my website Starobserver.eu, but for now, here’s the sketch to enjoy.

Deepsky in the Dordogne
In the first week of October I visited the Dordogne together with two other deepsky observers, Jo and Angelo. We rented a holiday home from Ad Mathijs from Astro Techniek. We were very lucky with the weather during this week. In the daytime it was almost every day between the 20 and 25 degrees, and the nights were very mild and......... clear! 5 nights out of seven on which we were able to observe. We had two big telescopes with us. Angelo took his 10-inch Meade and Jo had his 12-inch Orion Optics UK telescope for the deepsky and the Coronado PST for solar observations. I used the 14-inch telescope that comes with the holiday home. We also had a range of binoculars with us, an 8x42, 12x60, 12x80, and 15x80. Al could be mounted on the SkyWindow.

The 100 meter radiotelscope in Effelsberg
On Saturday the 16th of October I visited the 100-meter radio telescope from the Max-Planck-Institute in Effelsberg, Germany. With this giant telescope it is possible to map large parts of the night sky in different wavelengths. Objects in our own galaxy, but also other nearby galaxies can be studied.

What I found very impressive was the speed with which this giant disc can be turned into different directions. The 100-meter large disc is simply impressive to see! Here are a few images of the telescope. Just click on them to enlarge.

Two sundogs in my backyard
On september 12th around 18.30 hours local time I saw two really beautiful Sundogs from my backyard. On could be seen between two neighbouring houses, the other right over another neighbour's house. Here are a few shots I shot with my compact camera.

First light for my 12-inch on an Equatorial Platform
Almost three years I have been observing with my 12-inch Dobson from Orion Optics UK. I love to work with the Dobson. The setup goes very quickly (five minutes) and I'm ready to observe. I also like the fact that you can push the tube to any direction when starhopping, without having to use electronics. However, about one and a half year ago I took up sketching again, and very soon I noticed a big difference with my old telescope I used for sketching, an 8-inch Cassegrain mounted on an EQ-6. When using this set-up for sketching, the object stood perfectly still in the field of view, at any magnification.

Solar prominences shot with the DMK and the coronado PST
On the 13th of June 2010 I shot a few movies of the solar prominences visible through the PST. The image below was created from a stack of 150 images selected from a total of 1500 images (25 seconds of movie at a rate of 60 images per second). The image was stacked and processed using ASTRO II DC.

Venus and the Moon
Hi all,

Just before I went to bed tonight, I saw this beautiful crescent moon over my neighbour's roof. To the right of the Moon, right above the tree, I saw Venus. I got out my old Coolpix 4500 on a tripod and shot this black and white image.

Enjoy!
