Hi everyone,
Though I've had fantastic views and many an enjoyable night

with my 6" dob., the time has come for me to upgrade.

I am planning on upgrading to an 8 inch dob.

(after much brainstorming on a 10", I've concluded that I won't be able to comfortably handle this by myself,

so I won't be going there).
The 8 inch collapsible dobs are on sale at the moment for only $550, compared to the solid tube at $500. May I please ask for your help with regards to the pros and cons of the collapsible dob (aside from the obvious 3kg lighter weight)?
Some questions that cross my mind are:
1) Does this need colminating everytime it's set up?
2) It seems strange to have the scope open to dust and elements. Even if you do cover with a shroud, can dust get in (I loathe dust on my scope).
3) Is dew more of a problem with these.
4) Is it fiddly to put together in the cold and dark.
5) Anything else I should be aware of.
I am leaning more towards a solid tube,

however I want to make an informed decision before I go ahead and purchase, as this is the scope

that I plan to keep for a very long time to come.

Many thanks for taking the time to help me out .
Regards,
Suzy.
