I've finally upgraded from my 6" GSO dob to 10" Lightbridge

Absolutely wonderful scope, purchased it from Bintel and Mike was an absolutely champion of a guy with his help

Had no problem assembling the package, but noticed the red dot finder wasn't included in the box. Do the 10" LB come with red dot finders?
My second question is whats the best way of covering the secondary mirror ? I don't feel comfortable having it exposed in my garage as I know dust will accumilate over it.
Thanks guys for the help.
P.S: Not too sure how people consider 10" GSO portable (for a sedan)? We tried to fit the mount into my car (WRX sedan) and there was no way in hell it was going to fit, same with 12" LB. 10" LB fits snuggly in boot of my car
