3 Congratulations on your purchase of a quality Or ion telescope. Y our new SkyView Pro 100mm ED EQ is an e xceptional instr ument f or observing and imaging astronomical objects . The ED glass of the objec- tiv e lens ensures you’ll enjo y star , Moon, and planetar y images with far less color distor tion than seen in standard refractors.
4 1. Sta nd t he t rip od l eg s up rig ht a nd s pre ad t he l eg s ou t as f ar as they will go . K eep the tripod legs at their shor test (fully retracted) length, f or now; you can extend them to a more desirab le length later , after the scope is fully assembled.
5 Inserting the Diagonal and Eyepiece The SkyView Pro 100mm ED EQ comes with a camera adapt- er attached to its f ocuser drawtube . Loosen the two thumb screws securing the camera adapter to the focuser drawtube and remov e the camera adapter (see Figure 4).
6 3. Retighten the counterweight lock knob. The telescope is now balanced on the right ascension axis. 4. T o balance the telescope on the declination axis, first tighten the R.A. lock le ver , with the counterweight shaft still in the horizontal position.
7 ing throug h t he eyepiec e f irst with your gl asses on , an d t hen with them off, and see if the glasses restrict the view to only a por tion of the full field. If they do, you can easily obser ve with your glasses off by just re-focusing the telescope the needed amount.
8 tions, 2" ey epieces can giv e a wider field of vie w than standard 1.25" ey epieces. This is especially desirable for obser ving deep-sky objects, as many of them appear quite large, but f aint. Many obser vers own at least one 2" eyepiece in order to achie ve the widest field of view possible for deep sky-obser v - ing.
9 T o find Polaris in the sky , look nor th and locate the patter n of the Big Dipper (Figure 9). The tw o stars at the end of the “bowl” of the Big Dipper point right to P olaris. Obser vers in the Souther n Hemisphere aren’t so fortunate to hav e a br ight star so near the south celestial pole (SCP).
10 Alignment of the Polar Axis Finder Scope 1. Look through the polar finder at a distant object (dur ing the day) and center it in the crosshairs. Y ou may need to adjust the latitude adjustment L-bolts and the tr ipod posi - tion to do this. 2. Rotate the mount 180° about the R.
11 the polar axis finder from the mo unt. Look through the polar axis finder at a star (at night) or distant object at least 1/4 mile aw a y (during da ylight).
12 Calibrating the Right Ascension Setting Circle 1. Identify a bright star in the sky near the celestial equa- tor (declination = 0°) and look up its coordinates in a star atlas. 2. Loosen the R.A. and Dec. lock le vers on the equatorial mount, so the telescope optical tube can mov e freely .
13 hav e warm air currents r ising from them which distor t the image seen in the ey epiece. Similarly , you should not observe thro ugh an open or clo sed window fro m indo ors. B ett er yet, choose a site out-of-town, awa y from any “light pollution”.
14 Once you’v e centered the object in the ey epiece, y ou can s witch to higher magnification (shor ter f ocal length e yepiece), if you wish. This is especially recommended for small and bright objects, like planets and double stars. The Moon also takes higher magnifications w ell.

16 powers , images rapidly lose sharpness and clar ity due to “heat wa v es” caused by Sun-heated air . Remember to aim well clear of the Sun, unless the front of the telescope is fitted with a professionally made solar filter and the finder scope is covered b y an opaque mater ial or remov ed altogether .
17 guide star on the illuminated ey epiece’ s crosshairs. Once the object is centered in the camera and a guide star is centered in the reticle ey epiece, y ou’ re ready to shoot. Deep-sky objects are quite f aint, and typically require expo - sures on the order of 10 minutes .
