Andrew, here is my solution to fitting the Nexus to the TOA.
A piece of 3mm aluminium plate cut, drilled, bent, painted and attached to a Baader Quick Release finder bracket which is mounted to the tube counterweight ring......
( will also make a bracket to mount it to the T-Rex now that I have the TSA to cater for.. )
I also made a mount for the big scope on a pole attached to the rocker box...
Just a note on the Nexus DSC now that I have had some time to use it..... it is brilliant !!!!
I actually do my alignments using a Nagler 22mmT4 or a Delos 14mm,
I just locate the star, then defocus it till it fills about a third of the field of view and centre it ... 2 stars 90º apart,
from then on everything is pretty well spot on....
