After several cloudy and rainy days and nights, the ClearNightSky forecast looked good. I set up my Vespera telescopes to observe comet C220P/McNaught. I updated the comet coordinates (RA/Dec 02h 55m 24s, +09° 32′ 29″) as manual targets. Then set up overnight plans in Singularity for the Vespera telescopes to observe several other targets prior to comet 220P/McNaught. The first comet observation started at 03:00 then repeated every 20-30 minutes.
All of the telescopes were able to find and make several observations of the comet. The comet has a longer tail than it did on 10-August. It is brighter than the obsevations on 11-August, but the viewing conditions were not good that night.
The images below are not cropped. The images are processed with PixInsight or Sky Color Studio, and the straight out of the telescope (SOOT) 8-bit JPG reference. The 16-bit RAW/TIFF and cropped versions of the observation images are available on my PhotoShelter site.
