From Sandy Oregon, 30 miles east of Portland, at the home driveway – Saturn Observed February 28 ~ March 2 Through 10.1″ Newtonian- Large Pastel Sketch produced:
I observed Saturn through my 10.1″ Newtonian at medium to high power magnification (120X ~ 240X) on several evenings last week, in effort to see some detail in the rings and surface cloud banding. Seeing was medium to marginal at times through the evenings. Using Sol Robbins template and other images from the web to accurately proportion the rings, I rendered this 19” X 25” pastel impression showing about what is seen in a good medium telescope if one stands back say 25 feet from the full image on a standard computer screen. Saturn’s disc was sketched at 7 ¾” at the equator. The Cassini division was easily visible and the crepe ring only hinted at high magnification at 240x through a 5mm Super Plossl eyepiece through my 10.1″ f/4.5 Newtonian-Dobsonian telescope with average seeing conditions at times with glimpses through steady atmosphere.
The foreground was quickly added from imagination for depth and drama as a final touch, which seems to captivate a view from one of Saturn’s moons, possibly Titan with a suggestion to an ocean-scape.
The sketch was photographed with a Sigma 35mm DSLR under white balanced studio lights.
