Yes, I wasn't meaning to dish the idea of a reflector full stop, it's just the 8" orange tube didn't work. I think it's a combination of age (attributing to the focuser being tricky to use and collimation being less smoothly adjustable) and it's collimation at the time and being more susceptible to viewing conditions.
