Totally agree with the above post....and we are happy it is all coming together for you
I too sold the Vixen 80 fl yes of course we would miss it. But filling that 3 inch spot with the old Tak FC 76 was the only way I would let the Vixen go.....Yeah so the focuser on the Vixen 80fl worked fine but the focuser on the C-102fl needed the upgrade and the moonlite works really well for that scope.
Nothing wrong with thrift and frugality sometimes frugal is wise. All my scopes are used and just about all have been very very good.
En Re rings I would agree that the Vixen rings are very good. Paralax rings are great. I did like the look of Kastek rings
and recently tried more blue (actually silver colored) rings from Astro Huteck for the FC -76
