Then, without moving your telescope, adjust your finder scope to center on the object. That's all.

On some finderscopes, the tube is held up by a number of screws. It is possible (but not always easy) to realign the finderscope by tightening one screw and loosening another one (simultaneously). Also, the main telescope may need to be align every once in a while (the main mirror has to be perpendicular to the light path in most models). In reflectors, this is often does with three screws that push on the back of the mirror, while three other screws hold up the mirror cell into the tube (you have to play with the correct ones). And, in many telescopes, these screws are located just so that you cannot reach the eyepiece while turning the screws. You need an elaborate mirror system to see what you are doing, or you need a friend who can turn the screws while you look. However, if you are not experienced in that kind of stuff, don't play with the main mirror (at least, not yet). Try to see if there is a way to realign the finderscope. With everything turned off (and during the day), point the telescope at some distant, fixed land object (NEVER point at the Sun -- Never) like a church spire, a road sign, a light post... With the main tube pointing at that object, try adjusting the finderscope until the object is centred in it.<a href="http://www.safedebthelp.com/non-profit-debt-help.htm"> Raymond</a> It all depends on what kind of telescope and what kind of finderscope.

Find a distant object on the horizon (at least 100 yards away, preferably 1000+) in the main telescope and adjust the finder adjustment screws until it is pointing in the same direction. There's no real secret to it but it does become easier in practice. The only thing I'll add is that if your finder has two sets of adjustment screws (front and rear) be aware that each set has the opposite sense for the same adjustment - if you want to adjust the scope in one direction you can move the rear screw in one direction or the corresponding front screw in the _opposite_ direction.<a href="http://www.resumeminers.com/Global.htm"> Andrew S</a> It’s something you really need to do in daylight.
