Ron,
I too have a new Sony, (after being a Canon and/or Nikon convert) and love it, absolutely love it. The Zeiss zoom is the main reason, but it does things just as well, or nicer.
Astro use is limited or non-existent though.
Sony do make a couple of macros from memory, they won't be cheap, but they are available. Sigma and Tamron will also fit, you just need to stipulate the Sony Alpha mount.
