Comet C/2013 US10 (Catalina) – December 5th, 2015
Another session with comet Catalina. This time the two tails are finally better seen in the final images.
I had to travel further away from home this time, together with my wife, her brother and father, to a “joint-observing campaign”, near the town of Fundulea, Calarasi county. This was necessary since all of Bucharest and surroundings were again covered by heavy fog.
The equipment used for the following image was the TS 115mm F/7 APO Refractor and the Canon 550D camera, all riding the EQ6 mount. Only 30 frames, each a 1 minute exposure at ISO 3200, were acquired, due not to the fog this time, but to a lot of cirrus clouds. Both the dust tail (towards the bottom of the image) and the gas tail (towards the upper right) are visible this time.
My wife used a 65mm F/6.5 APO refractor and her Canon 550D, placed onto a EQ3-2 mount. She acquired 16 frames, each a 1 minute exposure at ISO 3200.
UPDATE (Dec 7):
I’ve reprocessed the image acquired with the 115 mm APO, this time with more attention to colors and background:
The reddish dust tail stands out better now.
Also, a couple of images depicting two other objects visible at the time, also acquired with the 115 mm APO Refractor and Canon 550D:
-Venus corona (due to the cirrus clouds):
-A colorful Moon shot:
