I have a 2 speed MoonLite focuser on my 80 apo and it is a work of art
. It is very smooth in use and I have had no problems with it at all. I got some custom alterations made to it at a reasonable price too as the standard version could not be collimated and this is the only way to collimate my scope as the lens cell is fixed. It is also rotatable. If the feather touch is vastly superior it must be bloody awesum coz my MoonLite is very good indeed.
