Finderscope Nylon Adjustment Screw 4. Insert the screws through the bracket and into the rear cell. WARNING: If you remove the mounting bracket, do not completely thread the screws back into the rear cell of the telescope. The screws may be long enough to obstruct the movement of, and possibly damage the primary mirror. Finder Bracket Rear Cell 2. P artially thread-in the three nylon thumbscrews that hold the finder in place inside the bracket. Tighten the screws until the nylon heads are flush with the inner diameter of the bracket ring. Do NOT thread them in completely, or they will interfere with the placement of the finder. (Having the screws in place when the finder is installed will be easier than trying to insert the screws after the finder has been installed.) 3. Slide the rubber O-ring over the back of the finder (it will NOT fit over the objective end of the finder). It may need to be stretched a little. Once on the main body of the finder, slide it up about one inch from the end of the finder. 4. R otate the finder until one cross hair is parallel to the R.A. axis and the other is parallel to the DEC axis. 5. S lide the eyepiece end of the finder into the front of the bracket. 6. S lightly tighten the three nylon thumbscrews on the front ring of the bracket to hold the finder in place. 7. O nce on, push the finder back until the O-ring is snug inside the back ring of the finder bracket. 8. H and tighten the three nylon tipped thumbscrews until snug. With the bracket firmly attached to the telescope, you are ready to attach the finder to the bracket. 1. Slide the O-Ring over the back of the finderscope and position it on the tube toward the objective end of the finderscope. 2. Slide the eyepiece end of the finderscope into the front ring of the bracket (the front ring is the one without the adjustment screws), then through the back ring. It may be necessary to push down the spring loaded pivot screw so that the finder will pass through the back ring. 3. Push the finder back until the O-Ring is snug inside the front ring of the finder bracket. 4. Hand tighten the two alignment thumb screws until they make contact with the finderscope. Pivot Screws Alignment Screws Quick Release Screws Installing the 9x50 Finderscope The 8" Edge HD and the 11" Schmidt Cassegrain telescopes come with 9x50 finderscopes used to help you locate and center objects in the main field of your telescope. To accomplish this, the finder has a built-in cross-hair reticle that shows the optical center of the finderscope. The finderscope must first be mounted in the included quick-release bracket then attached to the rear cell of the telescope. To install the finderscope: 1. L ocate the finderscope mounting bracket attached to the bottom portion of the finder bracket. Loosen the two thumb screws to slide the mounting bracket from the finderscope bracket. 2. F ind the two holes in the rear cell of the telescope on the top left, when looking from the back of the tube. 3. P lace the mounting bracket over the two holes of the rear cell on the optical tube. 28 I
