To move the telescope in the azimuth direction, loosen the azimuth lock knob, take hold of the telescope by the end of the optical tube, and gently rotate the telescope to the desired position. Then re-tighten the azimuth lock knob. To move the... - Page 5 When the EZ Finder II is properly aligned with the telescope, an object that is centered on the EZ Finder II’s red dot should also appear in the center of the field of view of the telescope’s eyepiece. Alignment of the EZ Finder II is easiest during day- light, before observing at night.

Objects will appear to move faster at higher magnifications, when the field of view is narrower. Remember that objects are inverted in the telescope, so when you move the telescope in one direction, the object in the eyepiece will move in the opposite direction than you would normally expect. - Page 7 700mm = 28x 25mm Every telescope has a useful limit of power of about 2x per mm of aperture (about 152x for the SpaceProbe 3 Altaz.)

SpaceProbe 3 Altaz. 6. Care and Maintenance If you give your telescope reasonable care, it will last a life- time. Store it in a clean, dry, dust free place, safe from rapid changes in temperature and humidity. Do not store the tele- scope outdoors, although storage in a garage or shed is OK. - Page 9 The secondary mirror itself should be cen- tered in the focuser drawtube, in the direction parallel to the length of the telescope. If it isn’t, as in Figure 6b, it must be adjusted. This adjustment will rarely, if ever, need to be done.

Star-Testing the Telescope When it is dark, point the telescope at a bright star and accu- rately center it in the eyepiece’s field of view. Slowly de-focus the image with the focusing knob. If the telescope is correctly collimated, the expanding disk should be a perfect circle (Figure 10). - Page 11 To clean the primary mirror, carefully remove the mirror cell from the telescope. To do this, you must loosen the three screws from the end of the optical tube that are flush with the end of the tube. Completely loosen all three of the flush screws (do not loosen the other three screws) until the mirror cell comes out of the telescope.
