[ATM] New home built 12" ultralight dob

["Alan Scott" <alanne1956@hotmail.com>]

I just finished a 12" ultralight dob, and wanted to ask for feedback. Any 
ideas on how to make it lighter or smaller?

Also, does anyone have any experience on making 3/4" aluminum tubes that 
split in the middle, yet are very stiff? How about graphite? I use a 
torsional attachment of the truss tubes with the mirror box.

Thanks!

Alan
