  2. Agenda... • Part 1 - Unguided Photography • Part 2 - Guided Photography • Part 3 - Afocal Photography • Extras…!

  3. Whats Covered... • Equipment • Processing and developing hints • Unguided and guided camera shots • Afocal shots using a telescope • Other hints and tips • Mistakes!

  4. Not Covered…! • Advanced processing techniques Film Doping (no drugs!) Push Processing • CCD imaging • Advanced telescope photography Eyepiece Projection Prime Focus

  5. Part 1 - Unguided photography • Not an expensive black art • Simple equipment • Many suitable subjects • Get to know your equipment! • Keep notes • Discussion

  6. Unguided Project Ideas... • Twilight and night time shots • Star trails • Constellations • Comets when they appear! • Meteor showers (difficult) • Aurorae when they appear!

  17. Pleiades 3SLR 135mm, F2.8, 10 min, ASA 1000 KRG

  18. Magic Formula... E = 550 / (F.Cos.D) E = Exposure time in secs F = Focal length of camera lens in mm D = Declination of constellation in degrees

  19. Examples... Using 58 mm lens… Dec Max exposure time before trailing 10o 9 sec 30o 11 sec 50o 14 sec 70o 27 sec 90o Infinity!

  33. Part 2 - Guided Photography • Manual or automatic? - Barn Door / Scotch Mount - Telescope slow motion controls with reticule eyepiece - Piggyback camera on telescope or other sidereal drive • Home made or commercial? - As simple or as complex as you like! • Accurate polar alignment and tracking • Discussion
