Equatorial mount – a type of mounting that allows the telescope to be aligned with the earth's axis in order to track the motion of the sky. Focal length - the distance from the optical center of the lens to the point where the incoming light rays converge, creating a clear, focused image. Primary Mirror - It gathers incoming light to create a sharply focused image. Reflecting telescope – an optical design in which light is reflected off of a curved mirror that converges the light into a small disk that is then magnified using an eyepiece. First, you need to take the time to familiarize yourself with the parts of your PowerSeeker telescope, then assemble it, following the easy instructions provided. Next, read over the operating instructions and become familiar with how your telescope works, to prepare for hours of viewing enjoyment. CAUTION: READ THIS SECTION BEFORE USING YOUR TELESCOPE Your PowerSeeker telescope is designed to give you hours of fun and rewarding observing. However, there are a few things to be aware of before using your telescope that will ensure your safety and protect your equipment. NEVER LOOK DIRECTLY AT THE SUN WITH THE NAKED EYE OR WITH A TELESCOPE. NEVER POINT YOUR TELESCOPE AT THE SUN UNLESS YOU’RE USING THE PROPER SOLAR FILTER. PERMANENT AND IRREVERSIBLE EYE DAMAGE MAY RESULT. NEVER USE YOUR TELESCOPE TO PROJECT AN IMAGE OF THE SUN ONTO ANY SURFACE, OR USE AN EYEPIECE SOLAR FILTER OR A HERSCHEL WEDGE. INTERNAL HEAT BUILD-UP CAN DAMAGE THE TELESCOPE AND/OR ANY ACCESSORIES THAT MAY BE ATTACHED TO IT. NEVER LEAVE YOUR TELESCOPE UNSUPERVISED, ESPECIALLY WHEN CHILDREN ARE PRESENT. THIS ALSO HOLDS TRUE FOR ADULTS WHO MAY NOT BE FAMILIAR WITH THE CORRECT OPERATING PROCEDURES FOR YOUR TELESCOPE. ALWAYS COVER THE FINDERSCOPE WHEN USING YOUR TELESCOPE WITH THE CORRECT SOLAR FILTER. ALTHOUGH SMALL IN APERTURE, THIS INSTRUMENT HAS ENOUGH LIGHT GATHERING POWER TO CAUSE PERMANENT AND IRREVERSIBLE EYE DAMAGE. THE IMAGE PROJECTED BY THE FINDERSCOPE IS HOT ENOUGH TO BURN SKIN OR CLOTHING. 2 P PPo oow wwe eer rrS SSe eee eek kke eer rr 1 111 114 44 Figure 1-1 3 T TTH HHE EE P PPO OOW WWE EER RRS SSE EEE EEK KKE EER RR 1 111 114 44 R RRe eef ffl lle eec cct tto oor rr The PowerSeeker is a Newtonian reflecting telescope that comes on an equatorial mount. This section instructs you on the proper assembly and use of your PowerSeeker telescope, which is shipped in one box, containing all the parts you need to assemble it. Unpack and lay out all of the parts in a large, clear area where you’ll have room to work. Keeping track of the parts, use the list below and the telescope diagram to confirm you have, and can identify each part. PowerSeeker 114 1. 5x24 Finderscope 12. Accessory Tray 2. Eyepiece 13.

Slide the two top portions of each tripod leg around the sides of each flange on the tripod mounting head (9). Make sure that the tripod center support brace hinges (13) are located on the inside of the each leg. 2. Slide the provided screws through the tripod leg and flange, until the screw extends out the other side mount (see Figure 1-2). Slide the washer and the nut over the screw and tighten. This can be left slightly loose, to allow for positioning the legs later, when attaching the accessory tray. You are now ready to attach the tripod accessory tray. 3. The tripod tray fits over the holes in the tripod's center support brace (13). Insert the winged bolts through the holes in each of the tripod center support braces and thread them into the holes in the accessory tray. Tighten all bolts to ensure proper stability to the mount.

Place the base of the equatorial mount (18) into the hole on the top of the tripod mounting head (9). 2. Rotate the equatorial mount until the declination axis (where the counterweight bar (16) goes) is positioned over one of the tripod legs. 3. Attach the mount to the tripod by threading the equatorial head mounting screw (11) into the bottom of the mount Before attaching the optical tube, the counterweight and slow motion controls should be added to the mount: 1. Thread the counterweight bar (16) clockwise into the declination axis of the equatorial mount. Slide the ...
