Nice work Andy,
now the problem will be to keep it in collimation
without the help from Dr. Diego.
I use a method with a laser aligner joined to a Takahashi 2x Barlow & I look for
the paper re-enforcement shadow from the center of
the mirror reflected back on to the collimator screen.
On my old 8" f6 Newt. it was easy but now
with a 10" f4 it's much more difficult to get right
but it's worth every minute spent on it.




cheers
Allan
