1) ST4 guiding will be perfect
2) Mount will track perfectly for 10 min exposures as long as autoguided
3) CDC works very well
4) Ver 2.5 gotos (except for planets) are very good as long as mount is level AND well polar aligned
5) ver 3.12 is very good as can SYNC on object but can use ver 2.5 with ascom and EQMOD (see yahoo groups) for extremely good guiding as well as goto without version 3.
