Follow Up...
Met up with CraigL last night, successfully used the 1.4x Extender on his Tak Sky 90.
Covered the pins on the camera side of the extender to defeat the error message with no problems.
There was enough clearance to allow the protruding part of the extender to even be used with a filter on the T-ring also.
Only downside was the slightly longer time we took to achieve focus. Either side of the focus sweet spot showed obvious colour aberrations, so being very critical in focusing is a must. (When isn't it!!??)
Our test subject was Eta under a full moon.
Will post images soon so you can appraise the differences in image scale, sharpness etc.
