AZ EQ6 - what are these numbers used for around the polar scope

[A40farinagolf]

I'm eventually getting to grips with my new mount but I can't find any mention in the instructions what I use these numbers for.

They are printed onto a thin aluminium disc can be rotated and there is a fixed datum marker at the 6 o'clock position. The numbers go from 0 - 12 and have finer graduations with E and W markings at the 12 to 1 position.

Any help would be gratefully received.

Thanks

These are part of the circular slide-rule that can be used for determining the position of Polaris at any time or date.

There are instructions on my websiteshowing how to use them.

Steve,

Many thanks for the link and I'll read it more thoroughly later.

As you will be aware the controller calculates a time at where Polaris appears on the circle around the NCP clock.

I have been putting Polaris in the small circle after setting the circle at the right time given above.

Is this correct or do I also need to use the instruction on the link to get better alignment
