Full Frame Vs Micro Four Thirds For Astrophotography

The Milky Way Core season is done for another year, with this video covering my last outing for the season. Ever since tracking became a staple of my night photography workflow I have been wanting to return to my Micro Four Third roots to see if the skills I've developed in the past half a decade of astrophotography would transfer through to better results. In this video I put my old M43 Panasonic GX85 and Full Frame Sony a7R against each other in a test of equivalence for the task of landscape astrophotography.

I'll caveat these results by saying that even at it's release the GX85 was not regarded as a good low light camera and this sensor characteristic alone the a7R dominates here. I am positive with more practice and planning I could get images produced by the GX85 to a level where it'd take an experienced eye to spot the difference. Point of the exercise is you don't need the latest and greatest full frame camera with super wide aperture lenses to produce pleasing astrophotography results. The key tool during acquisition here being a star tracker, everything else comes down to editing.

What are your thoughts? What gear did you start your landscape astrophotography journey with and what do you shoot with now?
