The pages from the Vixen Super Polaris Manual #6-8-31-8407-5S-69-Ko-Inu are being made available here for those numerous buyers of used Super Polaris Mount missing the original manuals. The manual itself is 18 pages. The seven pages provided cover the operation of the mount and installation of the DMD-3 motor set. Each page is available as two JPG files. The "Fast" files are about 200KB in size, blurry but readable. The "Good" files are about 1.1MB in size but of a much better image quality.

One thing that people find difficult (and for good reason) is figuring out how to set the East/West offset on the Polar Alignment time circle. The world is supposed to be divided into 24 equal time zones each 15 degress of longitude wide. Local political considerations may make a given time zone wider or narrower. The sky does not care about local politics. The offset dial on the mount is there to adjust you local time to the reality of the sky. To determine you particular mount's offset degrees and direction, you must know your local longitude and your local civil time GMT offset.

Divide your longitude by 15. Subtract your local civil time GMT offset from this value. If the value is plus you will use the West offset. If the value is minus you will use the East offset. Mulitply the results of the subtraction to give the number of degrees offset.

For example, I am at 122 degrees longitude. Dividing 122 by 15 gives 8.1333. My local GMT offset is 8. Subtracting 8 from 8.1333 gives 0.1333. The value is positive, so I use the West offset. Mulitplying 0.1333 by 15 gives 2.00. I set my mount offset to 2 degrees West.

Chicago is at 80 degrees longitude. Dividing 80 by 15 gives 5.333. Chicago's GMT offset is 6. Subtracting 6 from 5.333 gives -0.666. The value is negative, so someone in Chicago should use an East offset. Multiplying 0.6666 by 15 gives 10. Someone in Chicago should set thier their SP offset to10 degrees East.

Note: The signs and directions are for the Western Hemisphere. If you live East of GMT, change them.
