Your new SkyView Pro 8 EQ is designed for high- resolution viewing of astronomical objects. With its precision optics and equatorial mount, you’ll be able to locate and enjoy hundreds of fascinating celestial denizens, including the planets, Moon, and a variety of deep-sky galaxies, nebulas, and star clusters.
Re-tighten the mounting plate securing knob until the mounting plate is secure. Then, tighten the safety thumb- screw. The safety thumbscrew will ensure that the mounting plate (and telescope tube) will not fall off the EQ mount if the mounting plate securing knob should come loose.
(c) With the Dec. lock knob released, loosen the tube ring lock clamps a few turns ands slide the telescope forward or back in the tube rings. (d) When the tube is balanced about the Dec. axis, it will not move when you let go.
Figure 6. The view through a standard finder scope and reflector telescope is rotated 180°. This is true for the SkyView Pro 8 EQ and its finder scope as well. If you have trouble focusing, rotate the focusing knob so the drawtube is in as far as it will go.
Magnification is calculated as follows: Telescope Focal Length (mm) Eyepiece Focal Length (mm) The SkyView Pro 8 EQ has a focal length of 1000mm, which when used with the supplied 25mm eyepiece yields: 1000mm = 40x 25mm The magnification provided by the 10mm eyepiece is:...
To do this, release the R.A. lock lever and rotate the main telescope around the R.A. axis until the reticle is ori- ented with sky. For larger optical tubes, you may need to remove the tube from the mount to prevent it from bumping into the mount.
Figure 13. This illustration show the telescope pointed in the the four cardinal directions (a) north, (b) south, (c) east, (d) west. Note that the tripod and moutn have ot been moved; only the telescope tube has been moved on the R.A. and Dec. axes.
The Collimation Cap and Mirror Center Mark Your SkyView Pro 8 EQ comes with a collimation cap. This is a simple cap that fits on the focuser drawtube like a dust cap, but has a hole in the center and a silver bottom.
A simple star test will tell you whether the optics are accurate- ly collimated. 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 defocus the image with the focusing knob. If the telescope is correctly collimated, the expanding disk should be a perfect circle (Figure 19).
You can change your nighttime telescope into a daytime Sun viewer by installing an optional full-aperture solar filter over the front opening of a SkyView Pro 8 EQ. The primary attrac- tion is sunspots, which change shape, appearance, and location daily. Sunspots are directly related to magnetic activi- ty in the Sun.
Starhopping, as it is called by astronomers, is perhaps the sim- plest way to hunt down objects to view in the night sky. It entails first pointing the telescope at a star close to the object you wish to observe, and then progressing to other stars closer and clos- er to the object until it is in the field of view of the eyepiece.
T-ring for your specific camera model and the included camera adapter. First you must attach the included camera adapter to the SkyView Pro 8 EQ’s focuser. To do this, remove the 1.25" and 2" eyepiece adapters from the focuser drawtube (Figure 22a).
Water will run off a clean surface. Cover the mirror surface with Kleenex, and leave the mirror in a warm area until it is completely dry before reassembling the telescope. 11. Specifications Primary mirror diameter: 203mm (8")
