keck in motion
Bookmarked 732 weeks ago keck observatory operates two ten-meter telescopes atop the summit of mauna kea hawai039i keeping those telescopes on-sky every night is the summit crew of the operations department this video is dedicated to the guys of the keck daycrew who make it possiblethe video is a combination of two techniques many scenes were filmed as standard video then accelerated during editing to allow the motion to become clear examples of this are scenes of telescopes slewing and the interferometer delay lines movingslower subjects such as clouds or the stars moving across the sky were photographed as time lapse here a large number of still images were taken these are then processed and converted to video using photoshop cs5 before loading into the video editing software adobe premiere elements to construct the time lapse sequences sometimes required thousands of separate images quickly filling memory cards and exhausting batteries after dark it is long exposure time lapse that is used with individual exposures often 15 seconds to one minute longmany of the nighttime scenes are lit by moonlight this allowed good exposures while still capturing the telescopes with stars overhead a moonlit exposure of 30 to 60seconds can often appear as if taken during the day with the odd effect of having stars in a blue skya number of cameras were used in capturing the imagery a canon g11 canon 20da canon 40d canon 60d and canon 5d mkii were used for various scenes this often involved cameras setup on tripods while programmed to take exposures for hours at a timei must give credit to many folks who helped get the shots giving suggestions driving the telescope avoiding extension cords and generally putting up with cameras deployed to odd locations three scenes were photographed by fellow keck engineer and photographer mark devenot specifically the optic handling scenes mark also made a number of useful suggestions that resulted in other scenes and improvements

atmospheric flare from a minuteman iii icbm missile
Bookmarked 766 weeks ago footage from a webcam on the canada-france-hawaii-telescope on mauna kea in hawaii presumed to have been caused by a test launch of a minuteman iii missile from california on june 22 2011 the event was also captured by a camera on the subaru telescope and witnessed by an observer with night-vision goggles discussion thread:http:asteriskapodcomviewtopicphpf=29ampt=24251note: this clip plays back in real-time but the playback is not perfectly smooth due to the way the frames were captured and stored |
