Comet 41P - Tuttle-Giacombini-Kresak
in the Evening sky
April 2, 2017

 Finally a clear night, it seems lately it is many weeks between shooting sessions on comet due to pervasive thick clouds. The moon was just over 1/3 full and while waiting for Comet Johnson to rise after moon set, I went a few hours of exposure on 41P with the "Cometracker" which I have converted to a fast Astrograph. The deep exposure was to hopefully show a hint of gas tail, however all that I came up with here is a narrow extension of material pointing downward but still within the huge spherical coma.
