Hi Stellarquest,
I've had my 12"LB since March, and through neccessity and being very inquisitive, I've crawlled inside and out of this scope and with the advice of a very close friend and telescope builder I have the carried out the mods needed to turn a very good scope into a excellent one.
If you would like info on what needs to be done, please let me know.
These mods are good for all the LB's. even the up coming 16" which I see still suffers from the problems of its smaller brothers.
The reason the 12" suffers more from spring sag than the smaller ones is, 1. Mirror Weight, 2. The same springs are used on all the scopes, so they work well on the 8", ok on the 10" but bomb out on the 12".
You can just imagine how much sag the 16" mirror will have.
