[ATM] Hello & Mak Newt specs

[Max Mirot]

Hello,

I just joined the list. I have not built a scope in a few year.  Now have 
two I am working on.

Right now a tweeking a custom 12"  Mak Newt with optics from in Intes Micro.

The specs are as follows as per Intes.

Pri Mirror  =320 mm x 35mm thick
Corrector 310 mm x 26.2mm
Secondary 55mm

Corrector (rear vertex) to mirror front 1730mm
Pri to secondary 1670mm
Center to focal plan 312mm


focal ratio 6.3

If use Newt.exe with I get a 100% illum of about 7mm.

Would the central illumination be the same in a Mak Newt as a Newt?

What happens to the aberrations when the distance between the corrector and 
mirror are changed?
