keep in mind if you get a short tube achro -the planets will show lots of colour -which can be distracting.
for this reason i have a 5" maksutov (etx125 OTA) its really only good for lunar/planets because its long focal length means a small field of view ,
the scope is very portable -i have either a manual alt/az mount for it or a small computerised goto mount -the tune only weighs 3kg so is light & packs up inot a 40x20x10 cm bag
