"Burgundy style" dinner evening.....

Yesterday evening, we had a very nice "Burgundy style" dinner with the guys and girls from work. It was organised by Arjan van Dijk evenementen. We had a very nice evening with good food, drinks and nice music. The only thing you got was a plate, knife and cup. For the rest you had to eat with your hands of course!
This is me!
This is the table during our dinner!

Photographed Astroid 160/Una

Last wednesdayevening I tried to photograph NGC2903 (in the head of Leo). Unfortunately my goto was a bit off (set for Halley observatory in Heesch) so I ended up a bit right of the desired object. At first glance I thought this picture (a stack of 7 20min exposures @ ISO800 in the prime focus of my 200mmF5 Newtonian, riding a NEQ6) contained only stars, but a careful look at it shows many small faint galaxies. Some are standing really close to each other. What was also visible is a moving object (right bottom). A fellow astronomer found the answer in Starry Night: it is the asteroid Una.
Here is a crop showing some faint galaxies....
Look in the right bottom, there is an object moving there....

IC2497 with "Hanny's Voorwerp"

"Hanny's Voorwerp" was already a long time on my todo list. Last Sundaynight Leo Minor was in reach of my scope.
For me this is a record, IC2497 is a former quasar at 730 million lightyears distance. Just before it went out it lit-up a gas cloud which is now called "Hanny's Voorwerp" because Hanny van Arkel (a Dutch teacher) discovered it at the galaxy zoo.
This picture is a combination of 8 20min exposures @ ISO800 of my Eos400d in the primary focus of the 200mmF5 Newtonian telecope.









See the distinct "green" color, that is the "Voorwerp".
