Comet C/2012 F6 Lemmon
Taken by Cristovao Jacques on January 7, 2013 @ Australia, Siding Springs
Details:
Comet C/2012 F6 Lemmon using remotely from Brazil, the telescope of the itelescope.net service in Australia. This is a sum of 5 x 600 sec using a Takahashi SKY90 telescope and a one shot color CCD camera SBIG ST2000XMC

I photographed this beautiful southern Comet with telescopes remotely, ITelescope.net system. DK 500/2250 FLI6303e 13x60sec RGB
Comet C/2012 K5 Linear
Taken by Tamas Abraham on January 2, 2013 @ Zsambek, Hungary
Details:
There was a weak cold front in the Carpathian Basin on this evening which helped to sweep the clouds away. So there was starry sky at last, but just around the zenith. Fortunately the constellation Auriga stayed at the zenith with the fast moving guest comet C/2012 K5 (Linear). As the humidity was heavy with the unwelcome illumination of the rising Moon, I could take just 21x60 sec frames about the comet with my old Pentacon 4/200 telephoto lens (F/8) and Canon EOS 400D camera (ISO 1600) on an EQ-5 mount. Processing by Iris software.

here in Italy continues to sky not beautiful, thats why I use a remote telescope in Spain

Details:
K5 Linear is speeding across the evening sky at about magnitude 10-11. These images were made by using custom tracking rates for the comet, with an ASA 10N astrograph and STL11000 CCD.

Details:
I was expecting a small diffuse blob from Comet K5, yet the only longer exposure Ive acquired that night proved me wrong, to my big surprise. The comets magnitude was to be around +8.3, but the final aspect on the image showed a large diffuse tail with a well defined nucleus. The proximity to open cluster M 36 made the view ever more beautiful. I also took a series of exposures later which showed the very rapid movement of the comet. At the focal length of 520mm the maximum exposure at which the comets movement wasnt visible was around 30-40 seconds.
A small satellite also passed in front of the scene, connecting the two heavenly objects.
Great little comet !
Ive also uploaded an inverted view to better show the presence of the tail.

Wonderful first comet with a good tail in this 2013! 10 SC at F/2,6 CCD ST-10XME RGB for 12 min tot exposure.Great sky!!!

This year is going to be one of the most memorable for sky watchers World-wide, especially for comet observers. Even if there are still almost a couple of months until the first big comet of the year (L4 PanSTARRS)will emerge from the glare of the Sun in mid-March, we still have a pretty nice comet just above our heads each night now. Its comet K5 LINEAR which at the moment is hanging around the Hyades, near Jupiter, and it will stay around for a few more nights. Quite a crowded sky-region.
Still the best is yet to come, at the end of the year, with a comet of the century apparition from comet S1 ISON.
The acquisition data is noted on one of the images. At the time of the exposures a thin layer of mist was surrounding the location, limiting the view of the comets tail.

Details:
Using my 8-inch (F/5) newtonian telescope I captured the comet C/2012 K5 Linear this evening from my backyard. The second image shows the circumstances. I took 25 frames with my Canon EOS 400D camera at ISO 1600 being on the telescope and each frame was 30 sec. Processing by Iris.
