Bugger Eric,

Wish I had read that before I bought the 5 inch SW135, would have saved me a LOT of time....

Still, you can only learn from mistakes. Its true that the inbuilt barlow/corrector is a pain,

FYI for any beginning amateurs wanting to buy a Skywatcher scope, ONLY BUY ONE with a P on the end, which indicates a Parabolic mirror, eg. Skywatcher 150 x 1000P EQ3-2 which would be the minimum I would get to start off.

Sorry if this is deemed off topic.

Chris
