Your telescope has a fixed aperture and, as a result, a fixed f/ratio. To properly expose your subjects photographically, you need to set your shutter speed accordingly. Most 35mm single lens reflex SLR cameras offer through-the-lens metering that lets you know if your picture is under or overexposed. This is important for terrestrial photography where exposure times are measured in fractions of a second. In astrophotography, the exposures are much longer, requiring that you use the “B” setting on your camera. The actual exposure time is determined by how long you keep the shutter open. More on this in the section on “Celestial Photography.” A S T R O N O M Y B A S I C S The Celestial Coordi- nate System28 Astronomy Basics Motion of the Stars Astronomy BasicsDefinition Polar AlignmentEquator 30 Astronomy BasicsFinding the Pole Latitude Scales 32 Astronomy BasicsPointingatPolaris DeclinationDrift 34 Astronomy BasicsAligning the R.A Setting Circle Polar Alignment FindersPlanets Observing the MoonObserving the C E L E S T I A L O B S E R V I N GSOLAROBSERVINGHINTS Using the Lens Cap Aperture StopObserving the Sun Celestial ObservingUsing the Setting Circles Observing Deep-SkyObjects38 Celestial Observing StarHopping 40 Celestial Observing Sky Illumination Viewing ConditionsTransparency Seeing42 Celestial Observing C E L E S T I A L P H O T O G R A P H Y Celestial PhotographyCrescent Short Exposure Prime FocusLunar Phase QuarterThe exposure times listed here should be used as a starting point. Always make exposures that are longer and shorter than the recommended time. Also, try bracketing your exposures, taking a few photos at each shutter speed. This will ensure that you will get a good photo. If using black and white film, try a yellow filter to reduce the light intensity and to increase contrast Piggyback 46 Celestial PhotographyEktar 1000 color print Konica 3200 color print Projection Photography 48 Celestial PhotographyCare and Cleaning of the Optics T E L E S C O P E M A I N T E N A N C ETelescope Maintenance Dual Axis Drive System - #93523 50 Optional AccessoriesO P T I O N A L A C C E S S O R I E S Super Modified Achromatic SMA EyepiecesOptional Accessories 52 Optional Accessories Motor Drive System - #93518Const THEMESSIERCATALOGNGC# Type54 The Messier Catalog Type Star Name LIST OF BRIGHT STARSEpoch ConstellationAtlases FOR FURTHER READINGAstronomy Texts General Observational AstronomyCELESTRON ONE YEAR WARRANTY Celestron International 2835 Columbia Street Torrance, CA Tel FaxItem #21017-INST Price $10.00
