G day Malcolm,

I doubt you will see much difference at 66* compared to what you have now. I encourage you to do more research, I found this calculator to be very helpful;

http://www.davidpaulgreen.com/tec.html

It is always recommended to get to star parties/groups n try b4 buy. I found that difficult and cheated by seeing what other Dobbers had in their signatures n forum or google searching. There have been some great threads here, in particular I remember a recent contribution from ' mentalasastro?? mental4astro??aka Alex Massey of Gondawana Telescopes.

A couple of gems of wisdom from others;

The ep is half the scope, and

Invest in good eps that you will retain even if you change scope.

I also used an in expensive Barlow to check my seeing v increased magnification.

I am very hapi with my eps (half of em were bought via the classifieds here, pre used) the 100* n 82* even when barlowed have wider fovs that the planet can drift through giving me steady obs between nudges

Cheers, L
