Description

Jupiter imaged with a C11, Siebert Optics Modular Barlow 1.7x and ASI224MC camera from Hilo, HI.  I captured 4 images of Jupter from 1910-1918 UTC and derotated them in WinJupos.  Europa was the moon closest to Jupiter that night and I was able to capture the moon as a disk with surface albedo features.  I have added a 300% enlargement of Europa and the WinJupos simulation of Europa at the midpoint of the derotated image.  My image shows a dark middle area and a lighter southern area on Europa which can be seen in the WinJupos simulation.

Europa is about 1940 mi/3120 km in diameter (just a bit smaller than Earth's Moon) and was at a distance of about 376 million miles/606 million km.  To be able to image surface albedo features on a small object at that distance with amateur equipment is truly amazing and a testament to today's technology.
