Meade is OK. I have the 8", 10" and 12" SCT's no issue!!
The SW 180Mak ( I had the SW 150Mak) is very good FOR planetary and Lunar observing. No good for DSO's!
The f10 of the SCT is a good compromise for planetary etc and by adding a reducer lens, x0.63 gives a f6.3 which is usable on DSO etc. They have been used like that for the last 20 years.
If found the SW 150 had very small internal baffle tubes (f12) and wouldn't take wide angle eyepieces (or 2" eyepieces) and there were few if any reducers available for the rear cell threads (unless you pay $$$ and get a convertor to the SCT thread) and even then the FOV was restricted.
I'd have to say the SCT is more versatile and gives both planetary and DSO capablility.
(BTW I found it almost impossible to fit a guide scope to the SW150Mak without having to purchase expensive tube rings- which are non-standard and plates - there's no holes in the OTA to connect to! - check this out with your vendor...)
