- Images taken through a telescope of comet 67P in the morning hours of December 6th, 2015 on a montain top in Austria. In November of last year ESA probe Philae touched down on its surface, becoming the first spacecraft to land on a comet. It is still orbited and observed by space probe Rosetta.
Keep in mind that the comet is way to faint to observe with the naked eye - it is even a challenge for long exposure photography.
Exposure time of each frame were 60 secs at ISO 3200 - Weather was extremely windy and some storm gusts shook the telescope.
I hope you enjoy! - Развлечения
Hi, I want to see comets' tails through my telescope, but, I have just a small telescope, it's 70mm Celestron Powerseeker refractor. What aperture do I need to see dust tail and gas tail on comets? I mean, comets with a magnitude +9 or +10, what aperture do I need to see the tails with that magnitude? And of course, without astrophotography methods or camera use, just naked eye through the eyepiece.
Dear Chico, unfortunately the comet is currently magnitude 22+ which is way to faint to see the tail even through a very powerful telescope. When I took the images the comet was around magnitude 15 - I could not see it through the 80 mm refractor - could only capture it by photography. But it will reach magnitude 12 again in May 2018.
Hey, thanks =) Well, I know that. But, I only want know what aperture do I need to see comets with details like the coma and the tails, because, with catalina US10 comet I could not see the tails on it through my 70 mm refractor. It was very difficult and even the coma. Of course, I live in an area where the light pollution is very high (level 7 in Bortle Scale).
I wanna buy a new telescope, for that reason I need to know that. What aperture do I need to see comet's tails and coma through the telescope? without filter or cameras or astrophotography, just the naked eye through the eyepiece without problems in a dark sky. Comets with magnitude +8, +9 or even +10 when the tails can be more visible.
