Title

Object/Date: Comets C/2016 U1 (NEOWISE) & C/2015 V2 (Johnson) @ December 1,2016 Description: Two new comets in approach to Sun casually concur into same field near Whirlpool Galaxy (M 51) in this image taken on December 1st, 2016. At the left bottom, the recently discovered C/2016 U1 (NEOWISE) shows a fuzzy and green coma due to its composing of ionized carbonic gas, while at upper right is the comet C/2015 V2 (Johnson) with very different morphology, more dusty than gassy, it shows a small and whiteish coma from which departs a short tail of dust. Both comets could be observed using binoculars in the future: NEOWISE at the end of this month of December before immerse into light of dawn, of which perhaps will not come out because is possible the comet to disintegrate at approach to Sun; comet Johnson will reach its maximum brightness on next spring 2017. Tech data: Takahashi FSQ ED 106mm. f/5.0 & SBIG STL-11000M (L:3×180s bin1 + RGB:1x60s Bin2) remotely from Mayhill, New Mexico (USA)
