Great scopes I use my 6" in preference to any other scope I have. If this scope has the adjustable lens cell go for it. The EQ 5 is a OK for it too. As for a new focuser, I upgraded the R+P with a GSO Linear Bearing 2 speed and its terrific.And for bright things in the sky that turn a bit purple use the 4" apateure mask or a baader semi-apo filter and no more purple
