Losmandy Polar Scope


 

Eventually, I received my polar alignment scope for the G-11 from
Pocono Mts. Alas, there were no instructions so I tried to figure it
out. I thought I did but some evidence indicates that I didn't. Can
someone send me to a post that decribes the procedure. Thanks in
advance. S. Havriliak

Here are the instructions from the Losmandy web site:

The Polar Axis Finder is designed to minimize polar alignment set-up time while maintaining maximum
accuracy. The installation of this optional accessory is described in the section on Installing the Polar
Axis Finder. Here???s how to use it:

1. Turn the Polar Axis Finder illuminator on.

2. Place Polaris in the field of the polar axis finder by adjusting the mount in altitude and
azimuth.

3. Rotate the polar scope until the orientation of the constellations on the reticle matches the star
pattern in the sky (as seen with the naked eye).

4. Adjust the mount in altitude and azimuth until Polaris is in the small space on the line
between Eta h Ursa Major (Alkaid - at the end of the handle of the Big Dipper) and
Epsilon e Cassiopeia (Segin - the beginning of the W).

5. Note the second brightest star in the field.

6. Place this star in space on the line between Cassiopeia and the bowl of the Big
Dipper. If you can not get Polaris and this second star in their respective places, rotate
the polar axis finder until you can.

When finished, the mount is accurately polar aligned.


Note that there are three lines for the second brightest star to adjust
for precession.

These lines respresent decades. On mine they are 90 00 and 10 (1990, 2000, etc...)
(the new ones may be 00 10 and 20).

The star currently needs be between 00 and 10, but still very close to 00.

take care,
Rockett Crawford

Go to the files section of this group and download polar1.pdf. It
helped me understand what to look at. I also remade the polar scope
LED with a dimmer so it was easier to see the second star.

How do you do that? I would be interested in that information, but I can't seem to find the files section.
Thanks.

I actually align on THREE stars, notice the hash marks opposite the
second star. Using the three star alignment allows me to use the
manual
setting circles effectively to find objects and hold objects in the
center of the field at 450x for a half hour without adjustment, all
without the tedium of drift alignment. It works for me.

Thanks for the details. I assume that the other marking are for
the southern hemisphere is that correct.
