User manual CELESTRON FIRSTSCOPE 31052

[. . . ] Before your journey begins take time to read this manual to familiarize yourself with the operation and parts of your telescope. WARNING--NEVER LOOK AT THE SUN WITH YOUR TELESCOPE OR ITS FINDERSCOPE. PERMANENT AND IRREVERSIBLE EYE DAMAGE MAY RESULT AS WELL AS DAMAGE TO YOUR TELESCOPE. HOWEVER, YOU MAY ENJOY LOOKING AT THE SUN IF YOU HAVE A SAFE METHOD OF DOING SO, SUCH AS A CELESTRON SOLAR FILTER. Assembling Your Telescope 1) Your Firstscope 90AZ telescope should include all of the following: a. [. . . ] At low power, with the standard eyepiece, you'll be able to see the whole lunar disk at one time. Change to higher power (magnification) with an optional eyepiece to focus in on a smaller area. Keep in mind that the rotation of the earth will cause the moon to drift out of your field of view. You'll have to manually adjust the telescope to keep the moon centered. Consult a current astronomy magazine or your local newspaper to find out the current phase of the moon. Lunar Observing Hint To increase contrast and bring out visible detail on the lunar surface, try using different filters (available through your local Celestron dealer). A yellow filter works well for improving contrast. Observing the Planets Other easy targets include the five "naked eye" planets of our solar system, so called because they can be spotted in the night sky by the unaided eye. Mars can reveal a host of surface detail and one, if not both, of its polar caps. You'll be able to see the cloud belts of Jupiter, perhaps even the great Red Spot. In addition, you'll be able to see the moons of Jupiter as they orbit the giant planet. Saturn, with its beautiful rings, is easily visible at moderate power, as is Mercury. Most astronomy publications indicate where the planets are in the sky each month. 8 Observing Deep-Sky Objects Deep-sky objects are simply those objects outside the boundaries of our solar system. If observing with others, make sure no one stands in front of or directly below the telescope tube. The images produced by Type 2 seeing conditions don't move as quickly as those produced by Type 1 conditions, but the images are quite blurry. Type 2 seeing conditions are produced in the lower atmosphere, most likely by heat waves from the ground or buildings. To avoid the problems associated with Type 2 seeing, select a good observing site. Stable thermal conditions found near lakes and atmospheric inversions tend to produce good seeing. Avoid sites that overlook asphalt parking lots, plowed fields, valleys or shorelines. If you can't get a better location, wait until the early morning hours when the surroundings are uniformly cool and seeing is generally better. Type 3 seeing conditions are characterized by fast ripples that create shimmer in the visual field, affecting otherwise sharp images. For extended objects, fine details are visible, but images shift around the field. Stars are crisp points, but they rapidly shift small distances within the field of view. The cause of Type 3 seeing is turbulence in the upper atmosphere, which means the observer has no control over it. [. . . ] T-Adapter (#93625) - T-Adapter (with additional T-Ring) allows you to attach your SLR camera to the rear cell of your Celestron telescope. This turns your telescope into a high power telephoto lens perfect for terrestrial photography and short exposure lunar and filtered solar photography.
