I own the 10" SW, like mike said its a perfect balance of Aperature and Size, i can cart it around in a mazda MX 6 coupe, and a Lancer without problems.
Currently im designing a carry handle for the ota that i remember seeing from a computer case (Antec Lanboy) basically it has 2 rings with heavy duty clips with a strap that goes between, followed by a handle in the middle worked well. but i can carry the whole OTA out the door and onto the back yard lawn all up about 15/20 meters.
With that i can pick up the Taranchula neb, orion neb without problems. 47 tuc on good nights down to a 5mm ep.
thats what i have to say, and at $639 is pretty bloody good!
