Choosing an Eyepiece A telescope’ s eyepiece magnifies the image formed by the telescope’ s main optics. Each eyepiece has a focal length, expressed in millimeters, or “mm”. The smaller the focal length, the higher the magnification. For example : An eyepiece with a focal length of 9mm has a higher magnification than an eyepiece with a foca[...]

Center the object you wish to have identified in the telescope’ s eyepiece. 2. Navigate to the “Obj[...]

Alternate Alt/Az Alignments If you would rather set up your telescope without using automatic alignment, AutoStar II offers alternative alignment methods for both alt/az and equatorial mounting. During the One-Star and T wo-Star alt/az alignment procedures, you will (unlike the Automatic and Easy alignment procedures) manually place the telescope i[...]

Note: AutoStar II locates alignment stars based on the date, time, and location entered. The alignment stars may change from night to night. All that is required is for the observer to center the selected stars in the eyepiece when prompted. Tip: Try a Spiral Search The GO TO key also allows you to perform a “spiral search”. A spiral search is [...]

Periodic Error Correction (PEC T raining) If you wish to perform high-precision astrophotography , you may wish to “train” your telescope in order to keep objects that you are imaging dead center in the telescope’ s mirror during the photographic exposure. Periodic error correction (PEC) helps to remove the slight perturbations from center th[...]
