Oh I am a total hack. My thought would be to first get the kit 35-70 with an eye on the 20-35 as a more appropriate use case (wider, very marginally faster). I don't plan to start hooking up my telescope to anything given the massive number of permutations and combinations to consider (not to mention the size/weigth and the fact i can't travel with it). I am willing to learn some new tricks on stacking. I would be interested in maybe a very small 'tracker' but I don't plan to start hooking up actual telescopes to the body.

Hello, I am pondering a move to medium format. One driver for me is to be able to get better star shots. I am thinking the bigger sensor will help a fair amount. The question I have is which is then more important once you have a bigger sensor (aka 100s and 50sii are same physical size) - the higher megapixels to catch more detail (100s) or larger photo receptor sites on the lower megapixel sensor (50sii). My hunch is the 50sii.....but its more hunch than informed by experience with these bodies.
