After dinner on Saturday wearing a poncho me to the core to take advantage of this rare bird meaning in Germany night with good conditions for observing the sky.
Given the proximity prioritize -4 ° C versus light pollution, I just turned away a couple of miles to a clearing in the forest of the city, Stadtwald .
At that time there was no visible world, but it was an ideal opportunity to see some of the gems that are only in the winter (northern hemisphere). The most notorious, the Orion nebula.
Anyway, the biggest problem in and of cold nights, it is to keep yourself warm, but the frost. After hour and a half I had to abort because the form did not see anything. Just at that point and I had cold feet, so being able to quickly return home was fine.

new moon, no clouds, visibility half
The reference indicative of the winter night looking south is called the Winter Hexagon, it's easy to find, starting from the three Marys, Betelgeuse is the head of Orion and is "in the middle" of the hexagon. Rigel is the feet and is one of the vertices. From Rigel going to Sirius is the brightest star. Castor and Pollux are also distinguished fast. Hence, finding the missing vertices have the egg (as they say in Spain). The picture is not my only I added the names ... Googled out there!
1) Pleiades M45
Magnificent globular cluster, visible even without the aid of a telescope. Although more than 500 stars are the brightest 7, 135 parsecs away. The best point is at low power, since it has a large angular size (110 minutes). With the focal length of Bresser Arcturus (700mm) and 20mm eyepiece, x35 is an increase. Pleiades
2) Orion Nebula, M42
Grandiose as always in the middle of the sword of Orion. By far the best example of emission nebula (and nebulae in general)
3) Castor, α α Geminorum Gem
A - white, size 2
α Gem B - white, magnitude 2.9
separation : 4 "
Bright and easy to locate, but it took a bit to distinguish the two components, being very closely spaced angularly. With the eye of 12.5 mm (x56 increase) is quite visible. In fact I think are the closest I came to distinguish the Arcturus.
followed several unsuccessful attempts to find open clusters, notably M35 that was theoretically available, but could not be, the search was already with frost and I could barely place for fine tuning .
I said, the sky did not allow for much more than highlights ... anyway, it was worth.
