The Summer of Mars

In this timelapse sequence, San Francisco Chronicle photographer Jerry Telfer used a simple Web camera attached to his Meade 8-inch Schmidt-Cassegrain telescope to capture a sequence of images to a laptop computer. Compiled here as a 1.3-Mbyte animated GIF, this shows Mars viewed from near Robert Ferguson Observatory in Sugarloaf Ridge State Park between 1 a.m. and 2 a.m. on Aug. 24. Mars' south polar ice cap is clearly visible at the bottom of the planetary disk. (Expect a delay until the GIF has completely downloaded to your browser window.)

This picture was generated by RFO Docent Steve Follett  The telescope uses was an 8" f:8 Dobsonian with no tracking.  He then used a handheld Hi-8 video camera to shoot through the eyepiece and captured frames to his computer through a TV capture card. Approximately twenty images were "stacked" to form a composite and processed heavily in Adobe  Photoshop.

This next series of images were all taken by RFO Docent Len Nelson.  The first image was taken on 9-17-03 using a 5" refractor telescope and camera exposures at 1/60 of a second.

This next image was taken on 9-20-03 using RFO Docent Tom Burrow's 6" refractor telescope.

The next image was again taken on 9-13-03 using a 5" refractor telescope with a 32mm ocular, and a digital camera at 4x zoom.

This image was taken using RFO Tom Burrow's 150mm refractor telescope, using a 32mm ocular and a pale blue filter.

Finally, this last image was taken on 10-13-03.
