This was taken on the 15th when Europa was transiting Jupiter's disc. My old EQ5 wasn't holding in RA so I had to keep toggling the RA motor control button during exposures and in between filter changes to keep it in the frame.
I don't think the clutch was slipping so I suspect it may have been my batteries were running low. Anyway, this is what I got through an 8 inch Newt, 5X PM using my ZWOASI120MMs guide camera. 3.5min Video grabs processed in Pipp, derotated in Winjupos, stacked in AS3, wavelets in Registax and finished in PS. A little grainy but it captured the moment.
