Jupiter Rotation by Tamas Kriska

Image of the rotation of the planet Jupiter by MAS member Tamas Kriska.  He used the Buckstaff Telescope at our observatory which is a 12.5 inch, f/7.4 reflector.  The picture was taken with a 2X barlow at prime focus with his Canon 60D DSLR. The individual images were taken from a VGA movie (essentially taking the best images out of many) over 4.5 hours and then combining them using AutoStakkert with post processing in Photoshop to create this final animated GIF.

Partial Solar Eclipse on Oct. 23th was obscured in the Milwaukee area because of clouds. Our next chance will happen on Aug. 21, 2017. That one will be a total eclipse if you're willing to drive a bit. The path of totality goes through southern Illinois and Missouri! It's not too early to start planning. Click here for details.
