POLAR ALIGNMENT TELESCOPE AND ILLUMINATOR (PASILL)
This is the original model, which was shipped until January 2000.
It fits all 400, 600, 600E, 800, 900 and 1200 models (except the original black 1200s).
The polar alignment telescope (also called polar axis scope) will help you to align your mount with the precise north celestial pole. If
your mount is aligned properly, your drive motor will track celestial objects accurately throughout the night. This will allow you to sit back
and enjoy the view without constantly adjusting your telescope to follow stars that are drifting continually out of your eyepiece. If you
plan to take astrophotos, proper alignment is critical so that the images recorded on film are as tight and round as possible. Improper
alignment will result in elongated star images. The polar alignment scope is for use in the Northern Hemisphere only.
This scope utilizes a special-condenser system, which makes it possible to view the entire reticle in a single glance. The reticle has a
special setting pattern that makes alignment easy. The dark field illuminator is a red LED, which illuminates the reticle so it can be seen
clearly against the night sky.

- Page 2 Installation and Adjustments We recommend that you install and adjust your polar alignment telescope in daylight, without the telescope and counterweights, following the instructions in this section. Once the reticle is properly adjusted so its center circle is mechanically and optically aligned with your mount, the alignment will remain stable, barring any strong shock to your mount.
- Page 3 While looking through the polar axis telescope, make adjustments to the altitude and the azimuth adjustment knobs until Polaris and Delta Ursa Minoris (the last and second-last stars in the Little Dipper's handle, respectively) are within your field of vision. α...
