  1. IC 5067 (PELICAN NEBULA) Raven LaFave

  2. FACTS In the Pelican Nebula; Ridge following curve of head and neck Constellation: Cygnus ~1,900 light years away; 10 light years in diameter Northeast of Deneb Magnitude: 8.0-9.0 RA: 20h50m54s; Dec: +44 25 06 Emission Nebula Jets emitted: Herbig-Haro object 555 http://www.perseus.gr/Astro-DSO-IC-5070.htm

  3. HERBIG-HARO OBJECTS Named after George Herbig and Guillermo Haro What are they? Pillars indicate a Protostar http://www.noao.edu/outreach/press/pr03/hh555.html

  4. WHY WOULD I PICK SUCH AN OBJECT? 1st wanted to image M16 (Eagle Nebula) IC5067 was above the horizon! Detail http://www.phys.ncku.edu.tw/~astrolab/mirrors/apod/imag e/1406/m16_32block950.jpg

  5. IMAGING Telescope: 12 Meade LX200 CCD: ST -9XE camera with RGB filters 10 flatfields in each filter and 10 flatdarks; both at .05 exposure 5 Dark Frames at 3min. Exposure 15 unfiltered; 10 of each filter (BGR); all at 3min. exposures

  6. CCD SOFT Masterdark Masterflat: PROBLEM! Calibrate Align Combine

  7. Unfiltered Median Green Add Red Add Blue Add

  8. RGB COMBINED

  9. PHOTOSHOP Levels Curves Saturation Flatten MORE levels/curves/saturation

  10. FINAL IMAGE!
