Four Comets Tonight - 2P Encke, C/2015 VL62 Lemmon-Yeung-Panstarrs,
93P Lovas 1, C/2011 KP36 Spacewatch.
in the Evening sky
12/17/2016
| Currently,
there are no bright comets in the evening sky, except perhaps
45P which is far too low in the west to see from our location.
Here are four comet shots, taken in a 2 hour interval starting
around 8pm last night. They range in brightness from 14 - 16th
magnitude, and are primarily a dust component with only short
tails if any at all. None the less, there are many other galaxies
in their fields, and I went an labeled them with a circle and
the galaxies magnitude per Cartes Du Ciel mapping program. The
12.5" goes about 1.5 magnitudes fainter than the 10 with
the CCD, reaching well over 20th magnitude in 30 minutes, and
22 in one hour. |

The CCD window frosted over for part of this shot, a bit fuzzy but still recorded fine.
