Comet C/2017 E4 Lovejoy: an image (07 Apr. 2017)
After one cloudy morning, today we were back to C/2017 E4 Lovejoy, to capture it again. Some clouds were still there, but
The image above comes from the sigma clipping combination of eleven, 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. Despite some high clouds, the ion tail is beautifully captured and, as always, it shows 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.
