[COSMOPARADISE (Nick)]

Just an update, the adaptor ring has arrived from shop, RK ENGINEERING, and im very happy with the work Herman has done.
The ring twists beautifully and securely to the tube, and then the objective cell twists on to the ring very nicely.
A quick check up with my Hubble Optics Artificial Star shows a very nice and round airey disk and at high magnification shows just the slightest amount of flase colouring, i think, that is its not a bright white spot but slightly red green blue, however when slightly defocussed the concentric rings look quite even. So just to make sure and bring "FRANKENSCOPE" to life im sending it for collimation and test.

Not long to go now.
