Comet 41P/Tuttle-Giacobini-Kresak: an image (25 Feb. 2017)
Comet 41P/Tuttle-Giacobini-Kresak will reach perihelion next April, so we plan to capture a few images covering its apparition. Here it is the first one.
The image above comes from the average of six, 120-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. Further details are available on the image itself. South is up, west on the left. A nice coma is well visible.
The observatory is placed at 1300 meters above the sea level, in the Sonoran desert, providing one of the best skies in the world. This image was taken as part of a cooperation between the Virtual Telescope Project and Tenagra Observatories, Ltd., which will be announced soon.
