Peter,
collimation can be a bit tricky but by comparison to the AG12 it is a breeze. Perhaps it fell into place for me. I am now using two pieces of equipment. One is a Howie Glatter laser to centre focuser to the secondary. Then I use a Tak scope to sort out the primary to secondary. Final tweak on a star.
You will need a better focuser. I am sure the new focuser is ok but it cannot hold much weight. My preference is for a 3" Feather Touch. It is very sturdy and more reliable than the standard Moonlite. Although I am currently using a Moonlite 3" Nitecrawler which is very good, but totally unlike a Crayford.
You will need a secondary heater and shroud to reduce dew and glare on the optical surfaces, especially at Clayton Bay as it is dew city.
I don't know if the 10" comes with a camera tilt adjuster but you will need one of those to perform collimation.
If you get stuck I am sure you will know someone in the area that can sort it for you quickly.
