Above: Saturn at 4:38 AM CDT April 12, 2012 (9:38 UT), 17mm eyepiece and 2x Barlow (191x magnification). Saturn is three days away from opposition, and as of this photo is 810,707,000 miles from Earth (1,304,706,000 km) with an angular diameter of 18.97 arc seconds. Compare with these previous Saturn photos below:
Above: 6:13 AM CST 1-8-12 (12:13 UT), 8″ reflector telescope, 25mm eyepiece, 2x Barlow (130x magnification, but I resized the photo to make it appear on the same scale as the photo below). At the time of this photo Saturn was 948,348,000 miles distant from Earth (1,471,500,000 km), with an angular diameter of 16.82 arc seconds. You can see how much more the rings have “opened up” during the last nine months, and I’m pleased that I was now able to capture a bit of Saturn’s shadow on the rings, as well as a hint of Cassini’s Division.
Below: For comparison, a rerun of my photo from 3:23 AM CDT 4-14-11 (8:23 UT), 8″ reflector telescope, 17mm eyepiece, 2x Barlow (191x magnification). At that time Saturn had just passed opposition and was a “mere” 810,570,000 miles from Earth (1,304,487,000 km), with an angular diameter of 18.97 arc seconds.
Here’s the Moon at 6:34 AM CDT April 12, 2012 (11:34 UT), with 25mm eyepiece (65x magnification). Click to enlarge:
All with 8″ reflector telescope and LG VX8360 cell phone camera.
