Comet C/2015 ER61 Panstarrs: an image (07 Apr. 2017)
After its outburst announced a few days ago, we were able to image comet C/2015 ER61 Panstarrs, capturing its amazing tail, even if some clouds made life not easy.
The image above comes from the sigma clipping combination of nine, 60-seconds exposures, unfiltered, remotely taken with the 16″-f/3.75 Tenagra III (“Pearl”) robotic unit part of Tenagra Observatories in Arizona. The telescope tracked the apparent motion of the comet. The imaging camera is based on the KAF-16801 CCD. The resulting image scale is 2.4″/pixel. The tail reveals huge features, making this comet a true gem. Some clouds affected the imaging session, but at least we could grab something worth of the effort.
The observatory hosting the telescope is placed at 1300 meters above the sea level, in the Sonoran desert, providing one of the best skies in the world. This image is the first one coming from a cooperation between the Virtual Telescope Project and Tenagra Observatories, Ltd., which will be announced soon.
