    Default A blue comet and a blue cluster



    For several nights recently Comet C/2016 R2 (Pan-STARRS) appeared in the sky close to the Pleiades (M45). An unusual feature of this comet is that it is mostly blue. Comets tend to be all green because their head and tail(s) are abundant in carbon, which glows green when ionized. This comet is, however, mostly CO, which glows blue. I tried to be careful and keep the comet colors fairly accurate; the head is mostly C and therefore has more of the characteristic green.

    This image was captured using two mounts/scopes/cameras in parallel. The wide field was captured with a Borg 55FL refractor (200mm FL) with a closeup on the comet from an A-P 140ED refractor (840mm FL with 0.8x reducer), from 7-9 pm EST on 8 Feb 2018. After the usual messy comet processing the images from the two setups were combined.

    Thanks for looking!
    - Mike

    You really did capture the comet colors perfectly. And it's such an interesting combination ... putting the comet together with such a beautiful image as M45. I liked this one A LOT !!!
