Here comes comet Catalina
Comet Catalina is now visible through binoculars in the Northern Hemisphere, and it should be visible with the naked eye in the coming months.
Comet Catalina is now easily visible in binoculars, but spotting its double-tailed appearance still requires a long exposure. Chris Schur took this 30-minute exposure December 6 from Payson, Arizona, using a Stellarvue SV80S refactor with a Canon XTi camera at ISO800.
Gerald Rehmann caught comet Catalina using a 12-inch telescope and an FLI ML 8300 camera from Farm Tivoli in Namibia on October 1.
José J. Chambó imaged comet Catalina on September 17, 2015, using a remote telescope in Siding Spring, Australia. Here, the comet appears near the bright star Alpha Lupi. The photographer notes: "The coma shows a strong greenish emission of C2, meanwhile its dust tail is projected toward southeast with a longitude of more than 1.5 degrees."
