A Very Nice Occultation of Regulus (4 May 2017)
After days of cloud tonight was virtually cloud free (at first) so I set up Don the 8" Newtonian in between preparing dinner ready for the occultation of Regulus. Just after 7:00 I fired off some test shots ... then the battey ran out. It wasn't until just before the occulation that I got the amera back on again, and managed to get Rgulus just as it winked out.
After a longer recharge I set the camera up again (infinity-infinity imaging through a 20 mm Plossly lens on the 8"). There was a lot of thin cloud about but the Moon was still fairly clear. This time I tried something different and instead of taking static shots ran a video form my Canon IXUS. It worked pretty well excet a) going to video more undid the focus and b) the video is in quick time MOV format which I can't edit with any of my set-up.
Still, I got very nice, if slightly out of focus, video of Regulus coming out from behind the Moon, tming was pretty good too. Had to take a screen shot to show the emergence as I can't extract single frames from the video (or crop or resize or anything).
A very nice night. Compare these shots with the occultation of Regulus back in February.
Got the wink out but missed the exit, by half a moon lenght.
Forgot about telescope inversion, a bit embarrassing....!
kind regards, Alan
Don't be embarrassed, I had to double check on Stellarium because I was convinced it was exiting much further down.
Being with a crowd at Science Works must have been a blast!
