Attaching the Optical Tube

You are now ready to put the telescope optical tube (c) onto the equatorial mount (f).

1.Slightly loosen the screws that hold the mounting rings on the telescope in place.

2.Slide the rings apart so that each is at the same distance as the holes in the mounting platform.

3.Place the telescope tube on the mount so that the treaded post at the bottom of the tube rings go through the holes on the mounting platform.

4.Thread a wing nut onto the end of the threaded posts and tighten to secure the tube to the mount.

5.Tighten the screws that hold the mounting rings in place. This will keep the telescope from sliding back and forth in the mounting rings.

Attaching the Accessories

Your telescope comes with the following accessories:

•20mm eyepiece 1¼"

•4mm eyepiece 1¼ "

•3x Barlow Lens 1¼"

•5x24 finderscope

•The Sky® L1 Planetarium software

1.Remove the caps from the focuser draw tube (o).

2.Place the chrome barrel end of the eyepiece into the focuser. Lock it into place with the thumb screw on the side of the focuser.

3.Your telescope also comes with a 3x Barlow lens which triples the magnifying power of each eyepiece (see Magnification section of the manual). To use the barlow lens, insert the barlow lens directly into the focuser. Then start by using the low power eyepiece such as the 20mm, and insert it directly into the barlow lens.

Attaching the Finderscope

1.Remove the two small, silver thumbscrews located on top of the telescope tube. See Figure 2.

2.Place the finderscope bracket over the two holes in the telescope tube, lining up the holes on the finderscope bracket with those in the

telescope tube.

Insert the thumbscrews through the finderscope bracket and thread them into the telescope tube.

Using your Telescope

Moving Your Telescope:

To change the direction your telescope is pointing:

Figure 2

1.To move the telescope in declination (north/south) there are two

options. For large and quick movements, loosen the declination knob (see figures 8) when moving the telescope and then tighten the knob when you are near the position you want. For very small movements and fine adjustments, use the declination cable. The declination cable has a range of about 30° and if you come to the stop at the end of its travel, do not try to force movement when the declination cable has reached the stop. Instead loosen the declination knob and manually move the telescope in declination until you pass the object in the opposite direction. Then tighten the knob and reverse the direction of the declination cable.

127 specifications

The Celestron 127 is a highly regarded telescope within the Celestron family, known for its combination of portability, reliability, and versatility. This telescope is specifically designed to cater to both novice astronomers and seasoned observers, making it a popular choice for those looking to explore the night sky.

One of the standout features of the Celestron 127 is its 127mm aperture. This size is optimal for gathering light and allows users to observe celestial objects in great detail, from the craters of the Moon to distant galaxies. The telescope employs a Maksutov-Cassegrain design, which strategically combines mirrors and lenses to create a compact and efficient optical system. This design minimizes chromatic aberration while providing impressive image quality, ensuring that celestial objects appear sharp and clear.

The Celestron 127 offers a focal length of 1500mm, resulting in a focal ratio of f/11.8. This relatively long focal length is advantageous for high-power observations, making it possible to view planets in stunning detail. For instance, users can clearly see Saturn's rings or the surface features of Mars with the right eyepieces.

Portability is another major aspect of the Celestron 127. Weighing in at approximately 11 lbs, it is lightweight enough to be transported easily to dark sky locations, yet sturdy enough for regular use. The telescope comes mounted on a stable, easily adjustable mount that allows for smooth tracking of celestial objects as they move across the night sky.

Celestron integrates advanced technologies into the 127 model to enhance user experience. The telescope is compatible with various Celestron accessories, including computerized mounts for automatic tracking and GoTo functionality. This feature is especially user-friendly for beginners, who may struggle with manually locating objects.

The Celestron 127 is not only limited to astronomical observations; it can also be used for terrestrial viewing. The additional versatility allows users to take advantage of the telescope's optical capabilities during the day.

In summary, the Celestron 127 stands out as a well-rounded telescope that marries portability with advanced optical technology. With its generous aperture, Maksutov-Cassegrain design, and user-friendly features, it is an excellent choice for anyone eager to discover the wonders of the universe, whether it's their first telescope or an addition to a growing collection.
