Comet C/2017 E4 Lovejoy: an image (08 Apr. 2017)
While the Moon grows and its light floods the whole sky, we tried to image comet C/2017 E4 Lovejoy again, soon after our satellite set, while the morning twilight already started.
The image above comes from the sigma clipping combination of seven, 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 ion tail is still amazing, with many features.
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.
