Actually.. if you own a car.. a dob can fit easily if you are willing to sacrifice the back seat. For the size and weight of a dob.. it is not much of a difference with those telescopes with tripods and counter weights and host of other things to carry. The dob has a stand which can be carried with one hand.. and the Optical Tube (if you buy a bag from Orion..it can be carried on the shoulder). Basically, one person can carry the whole set.

I have played with all designs before....and I can tell you that the dob is the easiest to transport and set up if you have a car.Canopus Lim wrote:Actually.. if you own a car.. a dob can fit easily if you are willing to sacrifice the back seat.

The EQ mount has too many parts. If you add the scope, it really beats me how you can carry a eq mount and the scope on public transport. Honestly, I think an eq mount need a car as well. Maybe with some frens it is managable on public transport.
going very off topic already, but let's keep it that way.
i think the fastest to setup scope would easily be a dob. u guys should see chris dropping his 8" f/5 onto the base and start obbing immediately.
in terms of transportation, i do not know how many people can managed to squeeze into the doors of a bus with a 8" newt on their back and a base in their hand. i doubt i could squeeze in due to my size.
but the eq mount isn't any better. a sp/gp mount alone already can keep one busy. and u still have to carry a 8" sct with u, i think that's pretty demanding for 1 person to handle.
the gpdx, sphinx and much bigger mounts, forget abt handling those alone. u maybe be able to move it out the first time due to ur enthu, but u are not going to do it again.
packed into a car, i think both the dob and the eq sct would take up abt the same amount of space. truss dobs dominate in this area, a 10" teleport fits nicely into a seat and could be buckle nicely with the seat belt.
i guess the popularity of sct are mainly due to the amount floating in the 2nd hand market. dobs are rarely brought in due to shipping cost.
