The following two photos of Jupiter and four photos of the Moon were taken from the sidewalk in front of my house in Crofton, MD. I used my Celestron 130 SLT, a 2X Barlow (except for one of the moon photos), a MacBook Pro (courtesy of APL) and the club’s new Orion StarShoot Solar System Color Imaging Camera IV to take these photos. The hardest part of acquiring the images was focusing, since the image bounces all over the place when you touch the focuser (or any part of the telescope, really). Adjusting the gamma level before recording was also critical for the shots of Jupiter. I used the WebCam Monitor software that came with the camera to capture movies and stills. I used the open source Lynkeos software (which also came with the camera) to stack the movie frames into a single image. The whole process was a little frustrating at first. A little patience yielded some reasonable results. Here they are.

Here is a quick and dirty time-lapse movie of Comet PanSTARRS over the course of three evenings (March 12, 14, and 19). Details varied on exposures and lens from 1-2 seconds, 210-400mm, ISOs from 400-3200. If you look closely, you’ll notice that the angle of the comet tail changes over the course of these short clips.
The entire thing is about 40 seconds long. The first two sequences were from March 12. The last sequence from March 19. The rest from March 14.
Last week during the first opportunity for us to even see C/2011 L4 PanSTARRS, the barely 1-day old crescent moon was a few degrees away. I managed to do a very very short time-lapse of the two together as the clouds streamed by. Here is a still from that sequence of images.
