USING THE WIRELESS UNIT Preparation for GO-TO Slewing Automatic Slewing to Celestial Objects The celestial go-to navigation system stores the coordinates of vast numbers of celestial objects as the database and it allows you to find your desired celestial object of interest automatically. The moon and bright planets are found readily in the night sky as you can locate their positions with ease.

Ⅰ. Locating the Mount After setting up the telescope, locate the mount so that its R.A. axis points toward the north celestial pole if you use the telescope in the northern hemisphere. Unless you intend to take lengthy astrophotography, you do not need to align the R.A. axis precisely to the celestial pole.

APPLICATION Ⅲ. How to Use the Polar Alignme nt Scop e What is a Polar Alignme nt S cop e? Name of Each Par t The polar alignment scope is a small telescope equipped parallel to the R.A. axis of an equatorial mount so that it can precisely point to the north (or south) celestial pole.

Page 28
APPLICATION Polar Alignment in the Northern Hemisphere You align the equatorial mount to the nor th celestial pole (N.C.P.) in the nor thern hemisphere. The polar alignment scope utilizes 3 stars of Polaris, Delta Umi, and 51 Cap near the Nor th Pole. Positions of the above stars are plot ted on the polar alignment reticle. To locate the N.C.P., you match the three star s on the reticle with the three star s of the same seen in the polar alignment sc ope.

APPLICATION Note: Unlike Polaris which is a bright 2nd magnitude star adjacent to the N.C.P., the constellation Octans is made up of dark stars about 5th magnitude on average. The nearest star to the S.C.P. is Sigma Octantis, which is one of four stars forming a trapezoid in Octans, visible at 5.5th magnitude.

About PF-L Assist App The PF-L Assist app helps align a Vixen equatorial mount to the north celestial pole or south celestial pole by simulating the field of view of the polar alignment scope. The app displays the current night sky seen in your location, and it will guide you to match the orientation of the constellations on the reticle in the polar alignment scope with the constellations in the actual sky when you set up the equatorial mount.
Page 40
APPLICATION Precise Polar Alignment (Drift Alignment – for advance users) If you precisely align the mount with the provided polar alignment scope, the mount will keep tracking the celestial objects that are caught in a field of view of your telescope's eyepiece. It enables you to take exposures of 5 to 10 minutes with a telephoto lens of 200mm focal length or less in taking astrophotography.
Page 41
APPLICATION Align the mount to match the height of altitude with your observing site. Choose a bright star in the east or west sky near the celestial equator, and put it in a field of view of the eyepiece. Here, a star in the eastern sky is chosen.

Page 42
APPLICATION Drift Alignment in the Southern Hemisphere Align the mount to match the direction of the azimuth with your observing site. Prepare an eyepiece with an illuminating cross hairs reticle. Choose a bright star just south of the celestial equator near the meridian (due north), and put it in a field of view of the eyepiece. Turn off the power switch of the mount momentarily while looking through the eyepiece to see which direction the star moves.

The mount is set for use in the middle latitude zone (35 degrees Put back the bolt and tighten it securely with the Allen wrench. plus/minus 15 degrees in latitude) at Vixen’s factory. If your observing site is lower or higher than the range of the middle latitude zone, you need to change the current altitude setting to match the latitude of your observing place.
