NO TE: Seeing conditions vary widely from night-to-night and site-to-site. T urbulence in the air , ev en on an apparently clear night, can distor t images. If an image appea[...]

11 After displa ying "Then Press Enter ," the control panel displays tw o numbers, one on each line. F or example: "+35 -115." These two numbers are called " displace- ment numbers " and will assist y ou in locating a celestial object. 4. Move the telescope: Mo ve the telescope tube to the right or left and you will no[...]

12 Ne xt, move the tube upw ard or downw ard until the second displacement number also reaches zero . As you near zero , use the ver tical slow motion control ( F , Fig. 3 ) to mov e the optical tube. If you perf or med the alignment procedure correctly , Saturn will appear in your ey epiece. Y ou may need to center the image. 7. If you wish to dis[...]

19 General Maintenance Y our telescope is a precision optical instrument designed to yield a lifetime of re ward- ing applications. Given the care and respect due any precision instrument, your tele- scope will rarely require f actor y servicing or maintenance. Maintenance guidelines include: 1. A void cleaning the telescope’ s optics. A little d[...]

20 • If inside a warm house or building, mov e outside. Interior air conditions may distort terrestrial or celestial images, making it difficult, if not impossible , to obtain a shar p f ocus. F or optimal viewing, use the telescope outside in the open air instead of obser ving through an open or closed window or screen. • If viewing a land obj[...]

21 Celestial Coordinates A celestial coordinate system was created that maps an imaginary sphere surrounding the Ear th upon which all stars appear to be placed. This mapping system is similar to the sys- tem of latitude and longitude on Ear th surf ace maps. In mapping the surf ace of the Ear th, lines of longitude are drawn between the North and [...]

25 In the early 17th centur y , Italian scientist Galileo , using a cr ude telescope smaller than your NG or NGC , turned it to look towards the sky instead of distant trees and moun- tains. What he saw , and what he realized about what he saw , fore ver changed the w ay mankind thought of the universe . Imagine what it must hav e been like being t[...]
