[Averton (P and C)]

By co-incidence we ended up imaging Mars two nights in a row with only 42 seconds difference in time. Because of this you can see that Mars has rotated back just short of the previous night's position due to it's slightly longer day (~40 mins longer). In the animation, north is to the bottom left and Mars is rotating right to left but the second images appears to have rotated left to right because it hasn't completed a full revolution.
Unfortunately to get this animation small enough for the forum it has degraded the images somewhat but you get the idea.
