Jupiter is still impressive at this (late December) stage and on this side of the globe Oval Ba is approaching the limb and the white ovals seems to be much larger and pronounce at the NTrZ (North Tropical Zone) just above of the (red) barge.

Here is an image of the Elephant Trunk made with my SXV-H9 and ED80 telescope. Full frame can be found here:

I just got done with a Sh2-103 series and this is the first of three. This one is the central area and was taken with my MakNewt 8 inch F/4 and my QSI 583 CCD. The RGB was 3 hours in each color and the H-Alpha was 4 hours so the total time 13 hours. I used the H-Alpha lightly and blended into the RGB

http://astrofotos.at/index.php?view=det ... Itemid=134 I took this picture during my stressfully working day .....i drove my car and saw this beautiful place -
It was the perfect moment to enjoy this astronomical moment.
The snow - it was not much - came in the night before and changed the land in soft white.

Location: Gleinstätten - a village in the south of Austria
Date 20.12.2011 a little bit after 12 CET

Comet Lovejoy from the southern hemisphere. Note the presence of the EMU (AKA the dark dust lanes of the Milkyway) to the right of the comet. The Ion tail is also showing quite well too.

Solargraphy 2011

This is a solargraphy carried out in 2011 between the summer and the winter solstices with a pinhole camera from Rivas-Vaciamadrid, Spain.

I'm sorry I haven't had time to comment on the great images here.

I think my two favorites were Tunç Tezel's "Winter in Sahara" image, where the Milky Way appears to rise like blue smoke from yellow and red light pollution sources at the horizon, and Paul Haese's image of Comet Lovejoy, which appears to plunge towards the horizon like a daredevil diver while the ghostly dust clouds of the Milky Way grace the skies like a mirage.

I also love both the Pleiades as well as the Pleiades and Hyades image - I really like how the latter brings out the dust clouds in the vicinity of the Hyades, too. Why aren't the Hyades surrounded by great reflection nebulae like the Pleiades? Well, for one thing, it is possible that the dust clouds are not actually at the same distance as the Hyades, but just appear there at the line of sight. And second, the relatively yellowish Hyades couldn't produce the same brilliant reflection nebulae as the bright blue Pleiades anyway. Really interesting!

I really like the beautiful image of galaxy NGC 7793 and its microquasar. And the Fornax Cluster image is very impressive, especially at full resolution. Obviously I like the fine picture of bright blue galaxy NGC 4449 and its small, faint dwarf companion.

I really like the mildly humorous and well-composed "Mountaineer Moon" image, as if the Moon was going on a hike in the mountains!

I like the beautiful M38 and NGC 1907 image, as well as the Melotte 20 image. I had to check Melotte 20 before I realized that this is really the Alpha Persei moving Group. I like the turquoise color of Mirfak.

The Jupiter images are beautiful, and the Solargraphy image is fascinating.

The Star Trails under Moonlight image is really unusually beautiful and well-composed, and the Sh2 249 and IC 443 image brings out the relationship between these neighboring nebulae and their various levels of ionization in a fascinating way.

Thanks to everyone for their contributions!
