Sunrise on Copernicus
Here is a sequence of images taken over 4 hours of the Sun rising over Copernicus. The Moon rotates once every 27.3 days, so the Sun appears to travel through the Moon's sky 27.3 times more slowly than we see it here on Earth. The equivalent sequence of shots, if Copernicus was on Earth, would only be 9 minutes.

This imaging idea has always appealed to me. Did you take heaps of frames? If so it would be great to the animation.

Thanks guys. Unfortunately not Paul - just the three goes. Would like to do a continuous sequence - maybe next month.

Great series - I like it heaps - I will give it a go - the change is significant over 4 hours - I thought it would have been less!

I would also have thought the change would have been less. Very interesting.

I was surprised about the amount of change too. When I did the first image, I thought that the very shallow angle of the sun on the crater rim might give the best opportunity to see any change, so I took a couple more later. The longer the shadow the more noticeable any change. This maximised by Copernicus being near the centre of the disc, which gives maximum terminator angular speed, and a decent amount of time for imaging around first quarter.
