indicator is between the 18h 50m mark and the 19h 00m mark on the R.A. setting circle. 3. Lock the R.A. clamp to hold the telescope in place. 4. Move the telescope in R.A. using the slow motion control handle until the three on the vernier scale lines up with one of the marks on the R.A. setting circle. Remember, the R.A. indicator must stay between the 18h 50m mark and the 19h 00m mark on the R.A. setting circle! 5. Look through the telescope and the Ring Nebula should be within the field of vi

There are several methods of polar alignment, all of which work on a similar principle, but are performed somewhat differently. For each hemisphere, there is a point in the sky around which all the other stars appear to rotate. These points are called the celestial poles and are named for the hemisphere in which they reside. For example, in the northern hemisphere all stars appear to move around the north celestial pole (see figure 6). When the telescope’s polar axis is pointed at the celestial

Toward the front of the telescope tube, near the focusing assembly, there is a small bracket with a set screw in it. This is where the finderscope bracket will be mounted. To install the finderscope: 1. Slide the rubber O-ring over the eyepiece end of the finderscope and roll it 2/3 of the way up the finderscope. 2. Insert the eyepiece end of the finderscope through the bracket until the O-ring presses tightly between the finder and the inside of the bracket. 3. Tighten the three adjustment scre

The same formula can be applied to any of your eyepieces. Celestron offers numerous optional eyepieces to expand your range of magnification. Eyepieces come in barrel diameters of .96" and 1 'A". In general, 1 V*” eyepieces are of a higher optical quality and give you sharper images along with a wider field of view and better eye relief. Magnification through the telescope has its limits. These limits are determined by the laws of optics and the nature of the human eye. The maximum usable powe

Some of the terms and parts described in these instructions may be new to you, so a few commonly used terms you’ll want to be familiar with are defined below. Altazimuth mount - the simplest type of mount, with two motions: altitude (up and down) and azimuth (side-to-side). “Mount" refers to the part of the telescope that supports the tube, which carries all the telescope’s optics. Altitude lock - allows the telescope tube to be locked into place once a focused image has been set up, by tighte

Without this eyepiece, the image you see is reversed from left to right, when using the standard diagonal. To use the erecting eyepiece, remove the diagonal and insert the erecting eyepiece directly into the focuser (see diagram above). Then use a low power .96" eyepiece such as the 20mm, inserting it directly into the erecting eyepiece. Aligning the Finderscope 1. Point the telescope at a stationary object (e.g., a stop sign) at least 100 yards away. Looking through the eyepiece (make sure al

Make sure the tray is placed over the tip of the bracket, so the bracket doesn’t cover the holes cut into the accessory tray, allowing for full use. 3. Insert a screw—with washer—down through the accessory tray and bracket. 4. Slide the washer and wing nut over the end of the screw. Tighten the screw completely. 5. Repeat this process for the remaining two comers of the accessory tray. Installing the Telescope Onto the Mount 1. Slide the altitude slow motion rod through the adjustment hole.

This also holds true for adults who may not be familiar with the correct operating procedures for your telescope. ALWAYS cover the finderscope when using your telescope with a correct solar filter. Although small in aperture, this instrument has enough light gathering power to cause permanent and irreversible eye damage. The image projected by the finderscope is hot enough to bum skin or clothing. THE REFRACTOR TELESCOPE Your telescope is a classical, two element refracting telescope that com
