"having to accept spikes on the brighter stars..." If there is enough length in the cable then curve it into a spiral shape to eliminate spikes. You may have to add a stiff wire to make and keep the

Hi Gary, and all, I can definitely give a report on that Optec secondary mirror method of?focusing.Since it's especially suited to the Edge scopes,?it would be?appropriate here.It'll be at least
