  1. Hunting all the Messier ObjectsAstrophotography with a $40 Web Cam James Maughan RVAS February 21, 2005

  2. My Odyssey 8 8” Dobsonian from Coulter Optics

  3. Progress towards 110 Messier Objects

  4. Long Exposure Photographs- Camera Only - 16 sec maximum exposure - f/1.8 - 40mm equivalent - manual focus

  5. Iridium Flare (16 sec exposure)

  6. Northern Lights

  7. Modifications for Telescope - modified mount from 4” Newtonian - eyepiece projection - 4 to 8 sec exposure

  8. Comet Ikeya-Zhang

  9. Epsilon Lyra Double Stars

  10. Mercury Transit

  11. Jupiter Moons

  12. Saturn Occulation

  13. Saturn Reappearance

  14. Orion Nebula

  15. Asteroid 2002NY40 Flyby, 18 Aug 02 - 8 second exposures, - separated by 30 sec

  16. Meade 10” LX-50, and Logictech Quickcam 3000 - unmodified, 1/30 sec exposure, direct projection - K3CCD and Registax software

  17. Jupiter Processing For Noise Reduction

  18. Moon- Straight Wall

  19. Mars

  20. Saturn

  21. Jupiter

  22. Modifications for Longer Exposures - modify circuitry to bypass 1/5 sec exposure limit - K3CCD computer control

  23. Requires Accurate Polar Alignment - K3CCD to calculate RA and dec drift - Excel program to calculate angular misalignment, correction needed - adjust set screws as needed

  24. Periodic Error in LX50 Drive - Limits practical exposure length to appx 30 sec

  25. Crab Nebula

  26. Pluto

  27. Sombrero Galaxy

  28. Whirlpool Galaxy

  29. Ring Nebula
