The FLI gear and PMX from Bintel as they are now the authorised dealer for both companies.
Cfz on this would be tiny so automated focusing between filters is likely to be needed.
I went for the FLI Atlas focuser for this reason Chris as it will focus automatically. Once any systematic differences with filters are established the Atlas focuser setting can simply be changed with filter changes.
Even though the scope holds focus well as it has very low thermal expansion I will control the whole OTA's temperature thermostatically if there is any focus change as Melbourne's ambient can drop as much as 20C over a clear night.
Only real world use would give me an idea of what protocol to follow.
This may take some time!
