Finally a low angle shot so you can see where the Collimation Tube extends down into the Back Plate where that last turned shoulder would hold the O-ring that centers the Collimation Tube in the Back Plate.
The Collimation Nut is adjusted just about where it will be with the Mirror in place.
I'll make the Primary Conical Baffold before doing any more work on the Collimation Tube...waiting for Mikes latest revision using the 7" secondary diameter.
Happy 4th of July Everyone,
Play safely and Best Regards,
Preston
