Moon or shadow??

[legion48]

I was taking a quick first light image of Jupiter with my new OMC-140 and DFK and looking at the result, I'm not sure if I got Gannymede or it's shadow. The image was taken at 00:06 (UK time) today the 4th September. Can anyone advise?

I thought it was the shadow at first when viewing last night, but stellarium shows ganymede exactly at that point at 00:06, so i suppose it's probably a transit

I think you have captured Ganymede itself legion48 in this lovely image. Looking at charts for the transit in "Astronomy Now" shows egress of the shadow is at 11.57pm.

Best Regards,
