At last the weather was OK for seeing the C/2013 US10 Catalina. It's no Lovejoy nor Hale-Bopp, but quite nice little comet still.
Unfortunately my imaging session didn't go as smoothly as I'd liked. I think the previous time I did astrophotography with longer than 50mm lens must have been some time during the spring, so it wasn't too easy to shoot in windy sub-zero conditions, especially when the subject is just barely above the horizon! Lost quite a bit of data due to the 200mm lens being too warm and getting all kind of aberrations and misfocused shots.
But at least I got this single exposure which I'm happy with.
B version is a heavily stretched negative image to show the tail better.
