I must be doing something wrong. If I do a conversion (on the net) of pounds into Canadian dollars, I get 600 pounds = 1210$ CAD. The 12" LB is going for 900$ CAD. Clearly I'm wrong somewhere here. On the other hand, a 12" Sky-Watcher retractable Dob for 800$ CAD is good news.

Steve, one more question. Does the 12” come with a fan or maybe a rig to hook up one?

The specs are available for the 12” but not for the others. Does someone know what is the F/ratio on the 10”?
