  1. COLOR / FOCUS

  2. ENHANCED HYDROGENGALAXY IMAGING By Chris Schur

  3. Introduction • What is Enhanced Hydrogen Imaging? • Reasons for obtaining images this way: • Highlights a wealth of normally unseen details • Can be done with standard CCD equipment and telescopes • Produces images complimentary ultra deep remote observatory shots • Demonstrates the dynamics of galaxies in a dramatic fashion • Additional acquisition time is minimal • Tremendous Visual Impact with small additional effort • The Process Revealed…

  4. Process Example: Standard LRGB NGC2903

  5. Process Example: Enhanced LRGB NGC2903

  6. Objects in Aladin Database

  7. The Process:An Overview • First make a standard LRGB • Take additional Ha frames • Subtract Red data from Ha data • Add difference to Red, Green, Blue • Recombine color image

  8. Step 1: Create Standard LRGB

  9. Final LRGB image

  10. Step 2: Take Ha Frames

  11. Step 3: Isolating the Hydrogen

  12. Step 4: Combining Hydrogen with the LRGB

  13. Final M82 image

  31. Finally 2- M33 in Triangulum

  32. Finally 2- M33 in Triangulum

  33. Conclusions • Additional time spent very worthwhile • Galaxy dynamics revealed graphically • Here is a fresh approach to astroimaging • Home results rivaling the ultra long exposures done at remote observatories
