The system construction 1. The Yoke - The main mount where all components join together. 2. The altitude control s auxiliary knob. 3. Rack and pinton focusing knob. 4. Eye piece joint tube 5. Thumb screws for finder scope. 6. Finderscope - Allows users to locate an object they wish to view without need to look through the telescope. 7. Eyepiece - Can be changed to allow greater or less magnification power. 8. The altitudes control s clamping knob. 9. Right and left blocks These connect the yoke to the telescope. 10. The altitude control This allows the user to change the vertical positioning of the telescope. 11. Main tube of the telescope. 12. Horizontal locking auxiliary screw Allows the user to rotate the telescope then fix it in any position. 13. Mounting base of the Yoke. 14. Tripod legs. 15. Accessory dish Assembly instructions 1. Remove the tripod legs (14) from the box and then use the supplied large screws to lock each leg in place. Do not extend the legs as this will make the next few steps easier. You should then fit the tripod support onto the inside of these legs using the attached nuts and bolts. 2. Connect each leg to the mounting base of the yoke (13) with the supplied long screws and wing nuts. Push the long screw through all of the holes and on the other side pull the washer and wing nut, tighten slightly but [lot completely. 1. CONNECT THE LEGS 3. Stretch out the tripod legs and make sure it sits level. On the bottom of the accessory dish (15) there is a screw which screws into the centre of the tripod support. Turn the dish clockwise to tighten it in the centre. 4. Take the telescope out of the box a take off the right and left blocks (9) on the main tube of the telescope (I11). Position the telescope so that the covers face upwards. Once in the yoke. reattach the right and left blocks (9) using the supplied screwdriver, making sure that the small screw is fitted into the small hole directly below before screwing in the blocks. 2. INSTALL THE MAIN MOUNT Install the altitude control (10) on the telescope (11) by loosening the clamp on the right side of the yoke (13) and placing it in then using the screw, attach it to the telescope (11). 5. Install the finderscope (6) by taking the thumb nuts (5) off then place the finderscope (6) onto the bolts aligning it with the telescope. When aligned correctly. put the thumb screws (5) back on and tighten. 6. Place one of the supplied eyepieces (7) into the joint tube (4), to secure it in place tighten the locking screw on the side of the joint tube (4). 7. Now you can lighten up everything and extend the legs to a suitable height and enjoy exploring space and beyond. 3. POSITION THE DISH 34302 manual.indd 3 11-06-2009 13:04:00
The required magnification depends on the object being observed. The following general guideline is recommended for this purpose: Ideal viewing conditions are obtained if the magnification is not more than 15x-20x the diameter of the objective lens, i.e. an optimal magnification of 100x-125x can be expected with a 60mm diameter objective lens to observe most celestial objects. A lower magnification power is advisable for the observation of stars. 4. INSTALL THE MAIN TUBE If the field of view is wider then the object of observation is more easily located. The highest magnification power should only be used for particularly clear observation of the moon an object that is relatively close and exceptionally bright so that good detail resolution is achieved at high magnification ratios. Barlow Lens The Barlow lens increases the magnification of the telescope. This telescope comes with a 2xs Barlow lens which will double the magnification power of the telescope. The highest magnification is always obtained by using a Barlow Lens and this should only be used when viewing large and bright objects such as the moon and the brightest planets. 5. INSTALL THE FINDERSCOPE DO NO NOT USE THE BAKLOW LENS IN CON- JUNCTION WITH THE ERECTING EYEPIECE AS THIS PRODUCES A LOW RESOLUTION LEVEL AND THE IMAGE CAN NO LONGER BE SHARPLY FOCUSED. 7. TAKE OFF THE COVERS AND START LOOKING 6. INSTALL THE EYEPIECE Finderscope Since telescopes have a limited field of view, it becomes very difficult to locate a given star or planet. For this reason the telescope is fitted with a finderscope with a reticule for origination. The image seen in the finderscope is inverted. There is a process which essentially calibrates the finderscope so that it is aligned with stethoscope. 1. Insert the eyepiece with the lowest magnification and look at a stationary object which is easily recognizable no further than 300m away. Turn the telescope with the horizontal axle. and move the vertical axle until the object is in the middle of the field of view, and then focus the image. Tighten the appropriate knobs so that the telescope remains in this position. Operating Information The eyepieces and magnification Magnification values when using the prismatic eyepiece extensions and the exchangeable eyepiece. Eyepiece chart and theoretical power limits: Eyepiece Power Power with 2x Barlow lens H 20mm 35x 70x H 12,5mm 56x 112x SR 4mm 175x 350x 2. Now look through the finderscope. If the object seen through the telescope is not visible, and then release the appropriate knobs and move the finderscope until the object is in the centre of the field of view. Retighten all of the knobs and check if the image can be seen correctly in the finderscope. Adjustments can be finished once the image from the eyepiece coincides with the finderscope image. Each eyepiece offers different powers of magnification as shown in the above diagram. Selecting the Correct Eyepiece Magnification defines the power of a telescope to enlarge and image or to make it smaller in order to view the whole image. Example: 700mm focal length 12.5mm eyepiece focal length = 56x Magnification 34302 manual.indd 4 11-06-2009 13:04:00
Maintenance If the telescope is not used frequently it will naturally gather dust. In order to clean the exterior use a simple soft dry cloth. We advise you do this every time after a session of viewing. Cleaning the lenses is a different matter: all you need is a powerful manual blower and lens cleaning paper and solution. As this type of telescope is called a Reflector and is an open-tube design, the optics will gather dust. We advise that you do not attempt to clean the mirrors if you are inexperienced with telescopes. If the mirrors need to be cleaned we recommend you get it cleaned by more experienced users. Frequently Asked Questions Q1 : Why does everything appear to be upside down? A 1 : This is due to the optics used in the telescope. If you would like to view ground objects, use the T18 lens and normal vision will be restored. Q2: How do I fit the eye pieces? A2: You can fit the eye pieces into the viewing tube at the side of the telescope However, you can only use one at a time. Experiment with them so that you can find the one that gives you the best image. Q3: How do I use the Barlow lens? A3: You use the Barlow lens in conjunction with the eye pieces. First, you fit the Barlow lens in the viewing tube. Then you fit the eye piece at the end of the Barlow lens. This will increase the magnification of the eye piece. Q4: Everything seems to be blurred? How do I focus the image? A4: You can adjust the focus by turning the knob below the viewing tube. WARNING NEVER LOOK DIRECTALY AT THE SUN THROUGH YOUR TELESCOPE OR ITS FIINDERSCOPE. EVEN FOR AN INSTANT WITHOUT A PRO- FESSIONALLY MADE SOLAR FILTER THAT COMPLETELTY COVERS THE FRONT OF THE INSTRUMENT. NEVER LOOK THROUGH THE TELESCOPE INTO ANOTHER OPTICAL INSTRUMENT OR PERMANENT EYE DAMAGE COULD RESULT. 34302 manual.indd 5 11-06-2009 13:04:00
