Aristocrat 60mm Brass Refractor 2 ® Congratulations on your purchase of an Orion Aristocrat 60mm. Your Aristocrat 60mm was hand crafted out of brass and African mahogany. It is a sophisticated instrument that not only looks great, but also performs well with its quality optics. [. . . ] With your fingers, slowly rotate the focus wheel until the object comes into sharp focus. Go a little bit beyond sharp focus until the image starts to blur again, then reverse the rotation of the knob, just to make sure you've hit the exact focus point. Aligning the Finder Scope The finder scope is used to aid in aiming the telescope. It is a small, lower-powered telescope that sits on top of the main telescope. The finder scope (Figure 6) must be aligned accurately with the telescope for proper use. To align it, first aim the main telescope in the general direction of an object at least 1/4 mile away­the top of a telephone pole, tree, etc. Position that object in the center of the telescope's eyepiece.

The Aristocrat can accept any 1. 25" eyepiece (the most common eyepiece barrell diameter). Orion also makes several brass eyepieces that will provide different magnifications for your Aristocrat 60mm. To calculate magnification, or power, of a telescope-eyepiece combination, simply divide the focal length of the telescope by the focal length of the eyepiece: Telescope Focal Length (mm) = Magnification Eyepiece Focal Length (mm) For example, the Aristocrat 60mm, which has a focal length of 900mm, used in combination with the 25mm eyepiece, yields a magnification of 900mm = 36x 25mm Whatever you choose to view, always start by inserting your lowest power (longest focal length) eyepiece to locate and center the object. Low magnification yields a wide field of view, which shows a much larger area in the eyepiece. Trying to find and center objects with higher power (narrow field of view) is like trying to find a needle in a haystack! eras and have "false color" added. Our eyes are not sensitive enough to see color in deep-sky objects except in a few of the brightest ones. As you view objects in the night sky, you will notice that they slowly move out of the telescope's field of view. To keep an object in the telescope's field of view (to "track" it), you will need to make small adjustments to the altitude and azimuth position of the telescope. To move the telescope in azimuth (left/right), unlock the azimuth lock knob and turn the telescope a very slight amount. To move the telescope in altitude (up/down) loosen the altitude lock lever and make the needed adjustment. Remember that you are seeing these objects using your own telescope with your own eyes!The object you see in your eyepiece is in real-time, and not some conveniently provided image from an expensive space probe. Each time you work with your telescope it will get easier to use, and stellar objects will become easier to find. Take it from us, there is big difference between looking at a well-made full-color NASA image of a deep-sky object in a lit room during the daytime, and seeing that same object in your telescope at night. [. . . ] The Aristocrat's legs are made of Mahogany wood that has been lacquered for protection. As long as they are kept from excess moisture, they will not warp or bend. Should they be exposed to moisture, dry them with a towel as soon as possible. All the brass parts of the telescope have been treated to prevent tarnishing and discoloring. [. . . ]
