A couple of changes to the re-configuration. I have decided it is pointless to remove ALL the Sky90s from the array and I will simply replace Sky90(3) with the 3rd 200mm Canon lens. That way I retain 5 imaging rigs on the array.
The 2600MC has been ordered from First Light Optics so I am now awaiting delivery of the Astromechanics Canon lens focuser and the 2600MC camera.
