1. Astronomical Spectroscopy of Planetary Nebulae

2. Objective Taking spectra Determining chemical composition Imaging

3. Procedure Researched Ring and Blinking Nebulae 60'' for spectroscopy to determine the chemical composition 12'' for CCD imaging

4. The Ring Nebula

5. And Not These Kinds of Rings:

6. Ring Nebula Info 2,000 light years away from Earth Diameter is less than 1 light year White dwarf Magnitude of 15 120,000°C = 216,000°F = 120,273 K

7. Blue spectra

9. Green spectra

11. Red spectra

13. The Blinking Nebula

14. Blinking Nebula Info Blinking Nebula Info 2,200 light years away from Earth White dwarf Magnitude of 8.9 Blinks or disappears because the nebula is faint compared to its bright white dwarf star

15. Green spectra

17. Red spectra

20. Problems Weather conditions Green laser pointer interfered with green exposure for Ring Nebula Lack of time (blue spectra for Blinking Nebula)‏ Problems with CCD camera at 12'' Problems with IRAF

21. Cessation Enhanced our encyclopedism in our operose, quick- witted cerebrums about nebulae Ascertained chemical manuscript of nebulae Assimilated the implementation of the tremendous telescope, spectrometer, and the CCD camera Exhumed the eureka of how to vanquish a myriad of quagmires that betided We initiated a preeminent, tumultuous, raucous, do- si-do shindig at the 60'' !!!!
