I run a Star Adventurer with a 72mm scope.
On the plus side, it is easy to carry around, for example, I picked it all up from my driveway the other night and just plonked it down inside, i think all up it probably weighs in at under 10kg.
On the not so plus side (keep in mind, I dont have a HEQ5 yet), I dont think its that portable compared to running a HEQ5, personally, I still need auto guiding so I need a laptop so I need a power supply (80ah AGM that weighs about 15kg) and all the cables and such. It all fits in the back of the car but I think that would be the same as the HEQ5 really.
I think maybe the biggest change could be changing to the smaller scope, that might make a bigger difference then changing the mount.
If you wanted super portable, maybe a star adventurer with a dslr and shorter focal lens. I think as soon as you go much beyond 250mm, you will need accurate polar alignment (meaning guide cam and laptop or polemaster) and probably auto guiding.
Keep in mind these are just my thoughts from lugging my current setup out to dark sky site. Its all been very easy with very quick setup but I think if I added a HEQ5, it wouldn't change too much.

Chris
