Comet C/2017 E4 Lovejoy: an image (09 Apr. 2017)
With the full Moon making observations quite critical, we continue to follow up comet C/2017 E4 Lovejoy and its tail evolution.
The image above comes from the sigma clipping combination of ten, 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 full Moon was a serious issue, but the ion tail is still prominent.
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.
