Update.
I just thought of a brilliant idea -
make an adjustable sliding jig for the mirror:
I can get some aluminium & roll it so that it forms a tube &
can slide up & down INSIDE the carbon fiber telescope tube.
I would need to take the circular strengthening ring off the bottom of the telescope
in order to fit the aluminium tube inside.
The top end of the aluminium tube could have tangs bent over to mount the mirror holder
& I could drill a series of little holes 5 mm apart down the side of the Aluminium tube
so that I could move the tube up & down & lock it in with one screw
using one of the 6 holes that normally holds the strengthening ring.
( I could use 2 holes - one each side if I wanted to. )
That way I could just put the focuser in the position that I want with the camera & RCC1 inside it -
making sure that the RCC1 is not too far inside the tube past the focuser
& just try the mirror in many spots until I can get focus at that position.
I might even be able to slide it while I watch the laptop image coming back & see straight away!
That way I could get the right result in under 30 minutes.
Then I could build the right length spacer that I need or
cut the tube to the exact length.
cheers
