I have just found a review that mentions that the 20mm is an erecting eyepiece with this scope!! It is designed for terrestrial as well as astro use. Surprised they didn't mention that in the manual?
Personally I wonder why a maker would do that. An eq mount is about as useful as a chocolate fireplace when it comes to terrestrial viewing and having two eyepieces presenting different views just makes life confusing.
I think it comes back to marketing. These scopes are sold to beginners. The marketing dept put stuff in there about being able to be used for terrestrial viewing and beginners who simply don't realise that is, while technically correct, factually misleading are sucked in.
Rant over!!
