Comet Johnson on Apr 22, 2017, 04:00 UT. 13×300 sec @ ISO 1600, IDAS-LPS, Canon T3, TV-85 at F/5.6.

Here is Comet Johnson again from a relatively dark site.   I did not devote much time to it since it was not my primary target this night.   It is only a little over an hour of integration.   Perhaps it was a little too warm to use 5 minutes/ISO 1600 for exposures, at least with this low number of sub-images.  But, I didn’t want to have to shoot two sets of darks, so I stuck with one exposure length all night long.
