Morris Oxford Posted February 10, 2015 Share Posted February 10, 2015 As javascript jupiter predicted a transit and GRS this evening I thought I'd give it a go. Conditions were excellent so I took lots of webcam data. This is a quick first pass at one of the .avi's which I have to say is one of my best so far. But what is the other shadow? it wasn't supposed to be a double! Io and Ganymede on the right. Europa off screen to the left. Any Ideas? SPC900, revelation 2.5x barlow, skywatcher 200p. 2000 frames @ 10fps. Best 50% stacked in R6. Johnnyaardvark and stash 2 Link to comment Share on other sites More sharing options...
catman161 Posted February 10, 2015 Share Posted February 10, 2015 (edited) Hi I believe it is the moon Callisto transiting the disc and its respective shadow. Edited February 10, 2015 by catman161 Link to comment Share on other sites More sharing options...
Guest HykehamObservatory Posted February 10, 2015 Share Posted February 10, 2015 (edited) Hi, I was also out photographing Jupiter last night. The dark patch on the right is Callisto. I watched it as it moved onto the planets disc. A strange effect as the moon went from a bright star to dark patch as it started the transit. Unfortunately the night was a battle with neighbours heating vents causing turbulence and I had given up before its shadow started a transit.

Morris Oxford Posted February 10, 2015 Author Share Posted February 10, 2015 Thanks for the comments chaps. Looks like it was Callisto then. Also found this (amongst others) on stargazers lounge: http://stargazerslounge.com/topic/236455-jupiter-0902-from-bembridge-double-transit/ Had a go at some more wavelets but I don't think its much better (still one of my best though): Also a short avi of the event. I would have gone on longer but the secondary started to fog-up: http://vidmg.photobucket.com/albums/v287/bruceb/Jupiter/Callisto%20transit.mp4 Johnnyaardvark 1 Link to comment Share on other sites More sharing options...
