The C102-AZ is similar to the Firstscope AZ and all text referred to in this manual on the Firstscope AZ applies equally to the C102-AZ. The telescope is shipped in one box which contains the optical tube, altazimuth mount and all the standard accessories, which include: · · · · · · · 25mm SMA Ocular 1-1/4" (36x) - with 70mm and 80mm models 6mm F Ocular 1-1/4" (150x) - with 70mm only 20mm Plossl Ocular 1-1/4" (50x) - with 102mm only 6x30 Finderscope (for the 80mm and 102mm); 5x24 (for the 70mm) 45° Erect Image Diagonal 1-1/4" Slow Motion Controls Adjustable Wood Tripod (some models have an aluminum tripod) Unpacking Your Firstscope AZ Use the accompanying diagram (on page 3) to identify the various parts of your telescope for assembly and ongoing use. When setting up the telescope, find a large, clear area where the parts can be laid out. [. . . ] Image orientation through the finder is inverted (i. e. , upside down and reversed from left-to-right). This is normal for any finderscope that is used straightthrough. Use the slow motion knobs to center the object in the field of the finder. Look through the main optics and the object will be there (if you aligned the finder first). 9 Try using different optional eyepieces to see how the field changes with various magnifications. WARNING ! NEVER POINT YOUR TELESCOPE AT THE SUN UNLESS YOU HAVE THE PROPER MYLAR SOLAR FILTER. PERMANENT AND IRREVERSIBLE EYE DAMAGE MAY RESULT AS WELL AS DAMAGE TO YOUR TELESCOPE. ALSO, NEVER LEAVE YOUR TELESCOPE UNATTENDED DURING A DAYTIME OBSERVING SESSION, ESPECIALLY WHEN CHILDREN ARE PRESENT. Although overlooked by many amateur astronomers, solar observation is both rewarding and fun. However, because the Sun is so bright, special precautions must be taken when observing our star so as not to damage your eyes or your telescope. Never project an image of the Sun through the telescope. Tremendous heat build-up near the back of the telescope can damage any accessories attached to the telescope. Use a Celestron mylar solar filter to view the Sun in complete safety. These filters reduce the intensity of the Sun's light making it safe to view. With these filters you can see sunspots as they move across the solar disk and faculae, which are bright patches seen near the Sun's edge. Be sure to cover the lens of the finder when observing the Sun. This will ensure that the finder is not damaged and that no one looks through it accidentally. In the night sky, the Moon is a prime target for your first look because it is extremely bright. Often, it is a temptation to look at the Moon when it is full. At this time, the face we see is fully illuminated and its light can be overpowering. In addition, little or no contrast can be seen at this time. One of the best times to observe the Moon is during its partial phases (around the time of first or third quarter). Long shadows reveal a great amount of detail on the lunar surface. At low power you will be able to see the entire lunar disk at one time.
