Hi all!  While i sweat on getting my mirror back intact from the coaters,
i'm putting the finishing touches to the 10" truss/string scope i have
made.  I've got a cover for the primary mirror, but does anyone out there
have a neat, easy method for covering the secondary when its not in use?? 
I really just want to keep the dust off.  Anyhow, i'm using an offset wire
spider and a 50mm secondary. If anyone has any ideas, drawings or web-pages
they can direct me to,  i'd appreciate it.
