Thanks for all the information everyone. From my original question I was hoping to find out if anyone that had actually purchased one of these scopes and if they could give me a lead on how they operated. I have read and heard a lot about the 8" GSO RCs.
From what I can gather the 10" GSO RCs have very good optics, not very good focuser and don't weigh an enormous amount. Although I have not been able to find out how much they weigh. Somewhere between 12 and 15kilos I believe? I don't have any idea whether they are easily balanced or how much back play is required to gain focus when imaging. I am assuming that it would be quite a bit. Maybe up to 300mm.
I was expecting to buy a new focuser anyway. I bought a Moonlight for my ED127.
If the optics are good then the main battle is won.
Please let me know if any of this is wrong.
Frank
