Apparently since autoguiding was done fine before the LX600 regardless of 20% higher focal ratio, so I am not really sold on that alone since they are giving us 20% less focal length (went from 3000mm on the 12"LX200 to 2400mm on the 12"LX600).
But the Crayford style automatic focuser! is this useful inseatd of the optional Zero Image Shift electronic focuser? If I attache the Zero Image Shift focuser to my LX200 do I get the same result?
Or do I buy one of these http://www.optcorp.c...dual-speed.html
Or what exactly is the deal with this focuser situation! or improvement!
