Just on the Skywatcher 10 inch collapsible dobsonian...

It is fair to say that if the up-down, left-right movements are silky smooth then tracking a planet at high magnification will be a lot more enjoyable?

If I want to track a planet at high mag, at what magnification do I need to see detail on mars, the bands and red spot on Jupiter, or the ring shadow of saturn? Can I have a low magnification for these or do I really need to take it up?

And just on deep sky objects, how good is a 10 inch aperature for detail on fainter objects, particularly galaxies? I know that 8 inches will show the object but not necessarily certain details. Would 10 inches deliver all the good stuff or is it still noticably limited? Take for example some of the more well known galaxies that are favourites for viewing (say the Sombrero galaxy). Will the 10 inch show all the basic features or do I need even more aperature???

I've also googled a bit about equatorial devices for dobsonians. They seem to exist? Maybe someone has some experience with attaching some sort of device to a dob that allows the scope to follow right ascention on a curved axis?

And just something about the base, this is shaping up as the more difficult thing to transport around. I wanted to fit everything in the boot of my small car. I feel the collapsed scope should fit in??? But then there's the bloody big base! That surely can't fit in the boot aswell? For long car trips to go on holidays where car seats are taken and room is at a premium, is it possible to disassemble the base and put it back together after the trip?
