Re: [TCML] Primary

[Bert Hickman <bert.hickman@xxxxxxxxxx>]

Hi Stan,

That's really not a problem. You may need to raise the primary a bit 
higher to get the desired degree of coupling. As long as you provide a 
way to change the coupling between primary and secondary (i.e., to raise 
the primary plane versus the secondary or vice versa), you should be fine.

Good luck on first light!

Bert
