Thanks Keith,
I appreciate your thoughts. The vast majority of this scope's use would be from home. I was going to put some heavy duty wheels or castors on the base to roll it in and out the sliding doors. I have a station wagon but the scope would likely have to be placed on its side during travel which may not be a good idea. I have only seen these collapsible dobs from afar and even then likely only the 10 or 12 inch ones so I'm only peripherally aware of the size c.f. a traditional truss dob. Seems these details are handily omitted from the Sky Watcher website too! While I doubt I'll be seeking dark skies with it very often, to not have the option at all would be painful. I'm not affraid of big though, I very seriously considered buying the 25 inch SDM for sale in perth - but it comes with its own trailor
. I also carry the fully assembled VC200L and tripod around, however I imagine the SW16 is heavier and certainly a lot more awkward than the Vixen to get in and out of a vehicle!! I must admit though I'm a little daunted by making warranty voiding modifications to a 16 inch scope...
I'll go have a look at the prices to get a lightbridge shipped here.
