All of my Meade Super Plossl's are just fine, but they are of the 'Made in Japan' variety, & bought a few years ago. The later/cheaper ones, now, I think, are made in Taiwan or China & 'some' are being made 'specifically for longer focal length' telescopes. eg; Meade ETX's etc. I bought one last year n found the same focus/FOV prob just described. Not suitable for my fast f4.5 DOB. Ummm, the text on box said, 'ETX scopes'!!! Just be careful with your choices.
