Presentation Transcript

  1. Indoor Preparation • Plan the observing run. • Select a mix of objects. • Check your star maps. • Know and keep your equipment together. • Must have pencils, torch, paper, clipboard and clips. • Eye patch.

  2. Outdoors • Start with an easy object. • Don’t spend all night looking for something you cant find. • Plan the nights viewing. • Check limiting magnitude every ten minutes. • Note your start and end observing times. • Log in Universal time not GMT. • Take regular rest periods(note times) one hour is long enough.

  3. Observing sites • Always check out in daylight. • Take mobile with you. • Tell someone where you are.

  4. Recording your observations. • Date, I.E. 24hour format. • Start time • End time. • Weather conditions. • Note break times. • Instruments used. • Enter log ASAP.

  5. Star maps. • Star atlas, North is up and East to the left. • Use Finderscope, nudge telescope towards Polaris new stars will enter from the north edge. • Line up the crosshairs to show N.S.E.W. • Turn maps/Atlas to match the crosshairs.

  6. Heavenly moves • Stars rise in the East and set in the West. • They make one complete movement of the heavens in about 24 hours.(23h 56m). • They move en bloc, not altering their positions relative to one another. • Some Constellations are said to be circumpolar. • The altitude of the celestial pole above the horizon is equal to the observers latitude.

  7. Up and Down • R.A. is measured westward from the first point of Aries. • This is noted in hours, minutes, and seconds. • The first point of Aries reaches its highest point every 24 hours (culmination). • The R.A. of an object is the time between the culmination of the first point of Aries and the culmination of the object.

  8. Up and Down • Declination is the angular distance of a star North or South of the celestial Equator. • The declination of the North celestial pole is + 90. • Anything on the equator is 0 degrees. • Used together R.A. and Dec form a coordinate system to locate celestial objects.

  9. Shine on you crazy diamond • Apparent Magnitude. 2nd century BC. • Six naked eye magnitudes. + 1 to + 6. • Lower the number, brighter the star. • Each magnitude is sub divided I.E. 1.3 2.6. • Some stars are even brighter so get a – sign before a number. • Examples, Sirius,-1.4 Venus –4.4 full Moon –12.6 Sun –26.

  10. Shine on you crazy diamond. • Absolute Magnitude. • All stars assume to be at standard distance 10parsecs or 32.6 light years away. • Examples, Sirius + 1.3 Sun + 4.8, Deneb (Cygnus) Apparent magnitude + 1.3 Absolute – 7.3.Pole star + 2.0 to – 4.6. • Luminosities span a very wide range from a million X more luminous than the Sun to just a few hundred thousand X the Sun.
