Re: jA Comment on the Lenses

There is no internal aperture stop.  Those of you that have been around a 
while will understand why.  Elliot designed the lens system, then ran out 
of time for this project.  Meanwhile I had the lenses made and there was no 
mechanical design to house the lenses.  I then hired a consultant to design 
the lens tube.  Apparently he did not concern himself with niceties like an 
aperture stop or baffles.

If one of you know what to do here, then I would appreciate advice.  Seems 
to me there is some improvement that can be made with a little 
effort.  Hmmm!  I will have to look up the person who did the last check on 
the lens spacing that allowed me to get that fixed.
