Dual Transit

Jupiter Europa Shadow Transit
Jupiter Europa Shadow Transit

On the night of Dec. 20, 2011 I managed to catch a tansit of the Great Red Spot on Jupiter with the shadow of the moon Europa also tranisting near the GRS. The telescope used was a 120mm refractor at 125x while observing in my suburban Orleans, Ontario, Canada backyard. The sketch was done at the eyepiece and later cleaned up in Paint Shop Pro. The colour was added with coloured pencils and pasted into the reversed scan of the original sketch.

Clear skies,
Gordon Webster
