Greetings everyone,
I like to express my gratitude for Trevor W.
He offered he's unused Synta focuser.
A very generous offer, and admirable spirit.
I'll do the same when I have something unused.
The focuser will help me with my Cass. project.
At this moment not able to spend a lot of money for a high quality
focuser, but I needed one to progress.
With this, I can establish the design parameters of the mirrors, and start design a proper mirror cell and back plate.
The unknown parameter is the designed BFL.
Hopefully with the focuser and a star test I can establish this.
Thanks Trevor!
Mick.
