Hi Russel,,
Just wondering what this "milk jug washer thingy of the secondary" is & does etc, to my understanding I assume you have made a plastic washer out of a Milk container, but would like to know where it has been placed in/on the 2ndry assembly and what purpose has it been applied for,, advantage if Im not mistaken,, ?
Also, how do you find or rate the effects of Color abberations, inparticular on planets considering being an F/5 reflector ?
Thnx & kind Rgrds
