Kev,
Thats some nice mods you've done, or maybe I should say totally redone

Hi Bob,
The Bintel filter will do a good job. Try that before you spend the extra money for a bigger scope.
All dobs are a work in progress. I don't think there's one dob on IIS that hasn't been tweaked somehow!!

Please don't get me wrong a 16" will ALWAYS show more than a 12" with all things being equal.
The 16" with a 0111/UHC will see more than the 12" with the same equipment.
As I said before size, weight and price are the BIG considerations.
