Moon, Venus Comet Conjunction As I predicted six days ago, the conjunction of the moon, Venus with Comet Catalina was pretty cool this morning, and it'll get even better to pursue tomorrow morning:  http://activesole.blogspot.com/2015/12/moon-comet-catalina-venus-conjunction.html #Canon   #Astrophotography   #comet   #Catalina

Photographing Comets Comet Siding Spring will approach Mars tonight and pass the red planet tomorrow, Sunday October 19, 2014. I performed many lens and exposure tests on Comet Lovejoy in late 2013 and early 2014, with and without a star-tracking mount. Here are some of the results, rendered as time-lapse video. The music used for this clip is "My Celestial Spacesuit" by 2Placid: https://www.facebook.com/abstraktprizmuk See my YouTube channel for more night photography: http://www.youtube.com/user/JeffSullivanPhoto I'm processing time-lapse video from the total lunar eclipse last week, and the Orionid meteor shower is active this week, so I'll probably upload videos from those events later this week. I hope to also capture some footage of Comet Siding Spring near Mars, weather permitting. You can see a cool NASA visualization of how Comet Siding Spring will pass Mars in this video: http://youtu.be/FG4KsatjFeI #comet #Mars #cometsidingspring #astronomy #astropho...
