On Thursday night I will be comparing my GH2 to my GH3 with my 8" telescope. There are a couple of hidden features on the GH3 that could make it the best Astro Photography camera to date.

This thing is a real gem. If only these clouds would go away sooner.

These two pictures say a lot about the difference between the GH2 and GH3 for Astro Photography.

Sorry but what are you trying to prove with this comparison? The GH2 was given 2 EV more exposure (f/1.4 rather f/2.8, shutter speed and ISO the same) and thus reaches a brightness where you can see the noise. The GH3 image is pretty much at black level so less visible noise.

While the GH3 probably does better than the GH2 for noise at ISO 4000, this doesn't tell us a whole lot about the visible difference when the two are shot under comparable conditions.
