So, a four-pole truss (??) tube is a portable solution for 8-10" dobsonians. ...It is one of my unfinished projects....

Finally a tracking platform for us in equator countries!
True, but even a truss tube 8-10", you might still need a car.anat wrote:So, a four-pole truss (??) tube is a portable solution for 8-10" dobsonians. ...It is one of my unfinished projects....

I have taken train and bus with the 8" Portaball. But I am pretty sure I won't do it again. Not because it is difficult to bring around, but because it invited too much stares and that's even before Sept 11. If now, I am pretty sure the MRT officers will not let me pass.

My Orion XT10 OTA takes up the entire back seats, while the base takes the front seat (too large to fit in the trunk). Its portable, but you can't take along an observing buddy unless he/she hugs the OTA lying down for the entire journey!
We do it in the dark...

Let's give Sam Johnson a big hug and a beer!
grab'n go 10-incher :-)
eh, any idea if there's other options for tracking platform. the johnsonian nightrider at 25lb seems a little heavy and quite big at 24". the price of 600 usd looks fair though.
i saw the Osypowski Tracking Platform, but the cheapest model would be in the 900+ usd range. and once again it's not exactly light at 20lb.
i wonder abt the portaball version, heard it's only 12lb, but price not stated. cc seems to have ordered one, have it reached sg yet?

I ordered my portaball platform more than nine months ago and is still waiting for it. Very upset with Mag1 Instruments cause they don't even have the business ethics to tell me delivery would take so long when I placed my order. Furthermore I paid in full back then.MooEy wrote:
