[. . . ] Remove the contents of the box and place them neatly on your work surface. Once your refractor has been unpacked and assembled, you will not need the boxes for everyday storage and transportation. However, you should save the box in case you need to ship your telescope via a common carrier. To begin setting up your Firstscope AZ, start with the tripod and work up from there. [. . . ] This includes asphalt parking lots on hot summer days or building rooftops. · Hazy skies, fog, and mist can also make it difficult to focus when viewing terrestrially. The amount of detail that can be seen under these conditions will be greatly reduced. Also, when photographing under these conditions, the processed film may come out a little grainier than normal. · When using your telescope as a telephoto lens, the split screen or microprism focuser of the 35mm camera may "black out. " This is common with all long focal length lenses. If this happens, use the ground glass portion of your focusing screen. To achieve a very sharp focus, you may consider using a focusing magnifier. · If you wear corrective lenses (specifically glasses), you may want to remove them when observing with an eyepiece attached to the telescope. However, when using a camera, you should always wear corrective lenses to ensure the sharpest possible focus. If you have astigmatism, corrective lenses must be worn at all times. Aligning the Finder Accurate alignment of the finder makes it easy to find objects with the telescope, especially celestial objects. To make aligning the finder as easy as possible, this procedure should be done in the daytime when it is easy to find and identify objects. In addition, you will also be able to see the Moons of Jupiter as they orbit this gas giant. Most astronomy publications tell where the planets can be found in the sky each month. Observing the Sun, Moon, and Planets WARNING! Observing Deep-Sky Objects Deep-sky objects are simply those objects outside the boundaries of our solar system. They include star clusters, planetary nebulae, diffuse nebulae, double stars and other galaxies outside our own Milky Way. The Celestron Sky Maps (#93722) can help you locate the brightest deep-sky objects. You can "star hop" to an object from an area with which you are familiar. 10 Most deep-sky objects have a large angular size. And, because of their low surface brightness, they should be observed from a dark sky location. Light pollution around large urban areas washes out most nebula making them difficult, if not impossible, to observe. LPR filters enhance deep sky viewing from light polluted areas by blocking unwanted light while transmitting light from certain deep-sky objects. You can, on the other hand, observe planets and stars from light polluted areas or when the Moon is out. Photography Hints Your Celestron can be used for both terrestrial and astronomical photography. Celestron telescopes have fixed apertures and, as a result, fixed f/ratios. To properly expose your subjects photographically you need to set your shutter speed accordingly.
