April 13/09 Titan shadow transit of Saturn

April 13/09 Titan shadow transit of Saturn

One Little Black dot

On April 13, 2009, on and off between 01:30 and 01:50 PDT there were enough cracks in the clouds and thankfully no rain in between, to allow some views of the shadow transit. At 01:50 PDT (UT 08:50) I was granted a long enough clear spell to do this sketch. It's a newtonian view so south is up. This was seen using an f/8 6 inch dobsonian at 240X magnification.

All dots in the sketch are satellites of Saturn. From left to right they are Dione, Titan, Tethys, Enceladus and Rhea.

It's pencil on white paper but I inverted the background after I scanned it.
