Ex. 400mm . 25mm = 16X (magnification) 2. A 45° Erecting Diagonal Prism is included in the R80 or MC90 telescope. The Erecting Diagonal Prism is used to erect the image you will see. Astronomical telescopes are designed in such a way that the image you see may be UPSIDE DOWN and REVERSED. This is perfect for viewing celestial bodies. However, it will feel strange when observing a land object or a bird. Focusing Telescope: 1. After selecting the desired eyepiece aim the telescope tube at a land-based target at least 200 yards away (e.g. A telephone pole or building). Fully extend focusing tube by turning the focus knob. 2. While looking through selected eyepiece, slowly retract focusing tube by turning focusing knob until object comes into focus. Aligning Finderscope: If a GPS module is connected to the E- mount, the local time, longitude and latitude 1. Look through Main Telescope Tube and information will be received from satellites establish a well-defined target (see focusing 13 telescope section). Tighten all lock knobs (Declination, Latitude, Right Ascension, Horizontal Axis) so that telescope’s aim is not disturbed. 2. Turn on the red dot finder and look through the finder window. Adjust the red dot alignment screws to center the red dot on the object. 3. Now, objects located with the finderscope first will be centered in field of view of the main telescope. 4.2.3. Go to the Moon After performing these setups, the mount is ready to GOTO and track objects. The most common object will be the Moon. Press MENU button, select “Select and Slew” by press ENTER button. Select “Planets, Sun, Moon”, and using ^ or Ў button to select Moon. Press ENTER. The telescope will automatically slew to the Moon and lock on. It will automatically begin to track once it locks on to it. Use the arrow keys to center the Moon in your eyepiece, if it is not centered. Press BACK key to stop GOTO during the slew. Press ENTER key to stop the tracking. 4.2.4. Initial Star Alignment A simple alignment/synchronization can be performed to improve the GOTO and tracking accuracy. To do so, press MENU button, scroll down to “Align”, select “One Star Align” and press ENTER. A list of three bright object, such as Moon, Venus, and other stars, will be displayed for you to select from. Select an object using ^ or Ў key. Then press ENTER. Use <>^ or Ў key to center the object in your eyepiece. Press SPEED button to change the slew speed if needed. Then press ENTER to complete the alignment. Or press the BACK key to cancel the process. An alternate way is performing “Sync to Target”. To do so, press MENU button, select “Select and Slew” and press ENTER. Then select a known sky object, such as Moon from “Planets, Sun, Moon” menu and press ENTER. The mount will slew to the Moon. When the mount stopped slewing, the Moon could be just inside your eyepiece or way off. Press MENU button and scroll down the menu to “Sync to Target” and press ENTER. Follow the instruction, use < >^ and Ў keys to move the Moon in the center of your eyepiece and press ENTER. 4.3. Turn Off the Mount When finishing observing, always move the mount to Park Position. If the mount is not moved, no initial set up is needed when powered on the next time. To do so, press the MENU button, scroll down to “Park Telescope” and press ENTER. Turn the power off. 5. Use SmartStar®-E Telescopes 5.1. Manual Operation of a Telescope You may observe land and astronomical objects using GOTONOVA’s arrow keys. After the telescope was assembled (referring to Section 2. Telescope Assembly), flip the I/O switch on the telescope mount to turn on the mount. Use >,<,Ў or ^ buttons to point the telescope to desired object. You may need using SPEED key to change the slewing speed. 5.2. Slew to an Object Press MENU button, from the main menu, select “Select and Slew.” Select an object you would like to observe and press ENTER key. The GOTONOVATM 8403 hand controller has a database consists of over 5,000 objects. Use > or < button to move the cursor and Ў or ^ button to change the 14 number. A check mark “v” indicates the • Double Stars: It consists of 40 double object is above the horizon, and cross mark “X” means it is below the horizon. Only those objects above the horizon can be observed. In some catalogs, those stars below the horizon may not display. 5.2.1. Planets, Sun, Moon There are 9 objects in Solar system. 5.2.2. Deep Sky Objects This menu includes objects outside our Solar system such as galaxies, star clusters, quasars, nebulae. • Named Deepsky Objects: It consists of 60 deep sky objects with their common names. More information will be available by pressing HELP key. A list of named deep sky objects is also attached in Appendix C. • Messier Catalog: It consists of all 110 objects in Messier catalog. More information will be available by pressing HELP key. 5.2.3. Comets It contains up to 64 comets, with 16 pre- loaded comets. This database is customer upgradeable. 5.2.4. Asteroids It cont...
