Making a say a 12 inch f2.2 would be a challenge as would building somthing for it to ride in. ..anyways lets skip those details ...so you have your perfect mirror etc rather than fit a fastar make something.
Or could you just drop fastar and place the camera sensor in prime focus...or what?
I would rather buy a f2.2 fl mirror than make it...someone mustt sell them...I think surplus shed had something years ago but maybe not.
F2.2 on hand made home made carbon fiber rod housing...I wonder if you could lead up jusr three maybe four carbon fiber poles to where the camera sits?
