Hi guys and gals, I'm thinking about upgrading my dslr in the near future and possibly getting my current D90 astro modded. Is there anyone in Aus that will do this? f not can anyone recommend me someone overseas? Or should I just save my hard earned pennies for one of those Nikon D810a's? I know modded canon cameras are more readily available but being used to nikon I find the canons hard to use. Thanks in advance
