I guess the mirror weight is something they thought of, I can tell you now the 20" mirror weighs lot more then you might think at first.

I have to agree - I have two identical scopes - a 16" f/5 and a 20" f/4 - same design - same sizes, etc. While the 20" is by far the bigger light bucket, the 16" is much easier to use because the mirror is so much lighter and handier to tote around when setting up / breaking down. The 20" mirror alone (in its carry case) nearly tears my arm out of its socket - mucho effort!

Excuse me if I sound like an idiot but one of our members has a 12" Lightbucket..sorry....bridge and he has real bad problems with dewing and it's only a 12".
I mean something that size in this climate? How on earth could you keep the dew off it? I've enough diffs with the 105!

Good question. Where is Dave with his very big hair dryer?
