8. Press ENTER 4 The LCM then asks you to center in the eyepiece the alignment star you selected Use the direction arrow buttons to slew the telescope to the alignment star and carefully center the star in the finderscope Press ENTER when centered Then center the star in the eyepiece and press ALIGN In order to accurately center the alignment star in the eyepiece you may wish to decrease the slew rate of the motors for fine centering This is done by pressing the RATE key 11 on the hand controller then selecting the number that corresponds to the speed you desire 9 fastest 1 slowest The LCM will then ask you to select and center a second alignment star and press the ALIGN key It is best to choose alignment stars that are a good distance away from one another Stars that are at least 40 to 60 apart from each other will give you a more accurate alignment than stars that are close to each other Once the second star alignment is completed properly the display will read Align Successful and you should hear the tracking motors turn on and begin to track One Star Align One Star Align requires you to input all the same information as you would for the Two Star Align procedure However instead of slewing to two alignment stars for centering and alignment the LCM uses only one star to model the sky based on the information given This will allow you to roughly slew to the coordinates of bright objects like the M

29. PE For astronomical viewing out of focus star images are very diffuse making them difficult to see If you turn the focus knob too quickly you can go right through focus without seeing the image To avoid this problem your first astronomical target should be a bright object like the Moon or a planet so that the image is visible even when out of focus Calculating Magnification You can change the power of your telescope just by changing the eyepiece ocular To determine the magnification of your 16 telescope simply divide the focal length of the telescope by the focal length of the eyepiece used In equation format the formula looks like this Focal Length of Telescope mm Magnification 2A Focal Length of Eyepiece mm Let s say for example you are using the 25mm eyepiece To determine the magnification you simply divide the focal length of your telescope for example the LCM 114 has a focal length of 1000mm by the focal length of the eyepiece 25mm Dividing 1000 by 25 yields a magnification of 40 power Although the power is variable each instrument under average skies has a limit to the highest useful magnification The general rule is that 60 power can be used for every inch of aperture For example the LCM 114 is 4 5 114mm in diameter Multiplying 4 5 by 60 gives a maximum useful magnification of 270 power Although this is the maximum useful magnification most observing is done in the range of 20 to 35
