ISON

This morning, I also, in addition to Lovejoy, tried to capture ISON in the morning glow. It was not easy. But I managed to capture much of it with a long tail. Much longer than I anticipated. I had read somewhere that the tail was about 0.5 degrees long. But in my image, the tail extended to the edge of the frame, possibly further than that. Giving a length of at least 2 degrees. Unfortunately, my colors are weird, so I had to crop the image some to remove the most weird part. But at least my image shows the comet and it's long tail
Technical : Pentax K5, ISO 400, 38x30 seconds exposure. Teleskop-Service 80mm/6 triplet APO. Sky-Watcher EQ3 Pro Synscan mount. Stacking in DSS, processing in PS. Final adjustments in Irfanview.
EDIT : Fixed the colours.


Love(joy) is in the air

On the 17'th, I and an couple of friends headed up into the hills north of Oslo to see ISON and Lovejoy. And to try to photograph them. Lovejoy was a joy (no pun intended) to both watch and shoot. It was bright and with a lovely long tail. I have estimated the tail to be more than 2 degrees long. It certainly filled the view of my camera. Below is a 59 minute exposure of Lovejoy. I did take 60 minutes, but due to strong winds, two 30-second exposures had to be dropped. Thats why the two glitches in the startrails.
Technical info : Pentax K5, ISO 800, 118x30 sec exposure, Teleskop-Service 80mm/6 triplet APO. Sky-Watcher EQ3 Pro Synscan. Flats using homemade flat-box, darks. (Actually, there was no point in darks since Pentax K5 is practically noiseless. The darks were... well... dark. Even stretching them to the max revealed nothing. Just black.) Stacked in DSS, processed in PS. Final gamma in Irfanview.
EDIT : Fixed the colors.
