Hi Danny,

Actually, I considered it - well, sort of.
In order to make the AZ-EL adjustments repeatable or resettable after a field trip, I got hold of a small digital counter which I had planned to attach to the fork arm, and couple the counter's wheel to the elevation knob's shaft using a thin O-ring as a belt.

Also, the two AZ adjustment knobs (corn cobs?) were to get covered with a spiral pattern, printed on a transparent sticky sheet, so that a multiple of one rotation would be indicated by a set of marks along the spiral as they came up to a fixed pointer - sort of like a "calliper" spiral, as it emerged from the central block housing. I really don't know why AP painted the series of horizontal stripes, with reference markers on them. Perhaps it was a fashion statement, or just to show that the corn cobs moved when you turn them.
Anyway, may still do that to introduce analogue setting circles to the adjusters ... just for fun :-)

I hope you get good results with your DSI - you will get the stars, but you will still need an eyepiece in the nosepiece to actually see the reticle. Earlier today, I was doing some fitting tests with an old 0.96" Japanese eyepiece, slipped inside a 1.25" eyepiece tube, to see if some sort of an eyepiece holding adapter could be made to the PAS eyepiece. Still thinking about that.

Good luck on your tests,
Joe
