This will give you the exact time when the Sun is due North of your location.
I've used similar to set up my NEQ6 mount. The RA axis set level with a spirit level and a Baader film over the finder.
The view of the Sun should be exactly on the finder crosswires at the nominated time.
Yes that sounds good.
I may try and use a 150 mm refractor, as I have a sun filter (proper film) for it and an illuminated reticle for cross hairs er wires...Not with it swiched on of course.

And to make the exercise more interesting may try to work out angle of tilt as well. Elevation as I can work out that angle...should be fun to see if I can complete polar align from a noon Sun observation...and it would be so handy as one could get it out of the way before dark...say at a star party it would give you something to do during the day...and given your great link one should be able to do it at other times.

Anyways today was a fail cause I took Dad out for a shop and the time ran out plus I think it had clouded over. Took him to Jkar and he enjoyed it so much.
