I've emailed Meade a number of times and they FINALLY said that they can do an upgrade on my 8" EMC SCT. But I couldn't find out exactly what they DO when they upgrade it.
What I am trying to find out is what do they replace when they do the upgrade. From what I've read it's the corrector plate and primary mirror.
Do they also replace the secondary?
Do they recollimate it before sending it back?
Is it worth doing over buying a new ACF OTC?
