Details:
There was gusty mountain wind this morning blurring star images. The comet was easily visible in binoculars, though the tail was at the edge of detection. I estimated the comet brightness at 5.5 mag.
The first photo i a stack of two 30-sec. exposures at ISO 250. I used Nikon D5200 and Sigma 100-300/4 at 300, f/4.
The second photo is a wider field from 100mm.
