I have just acquired a nice (I think) 10" f6 Lightholder mirror from a CN classifieds. I'm looking for a quick way to mount this mirror on a structure, it seems like I can actually use a readily-available 12" f/5 dob structure for this 10" mirror. I'm thinking to either get the 12" Lightbridge structure or the Geoptik Nadirus kit (

Attached is the output of the Newt for Web calculations I ran. Notice that the same tube can be used for either mirrors without any sacrifices in performance (I have to modify the mirror cell and take care of the balancing).
Is this correct or am I missing something here?
Cheers,
Arief
