  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. 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

  7. Step 1: Create Standard LRGB

  8. Final LRGB image

  9. Step 2: Take Ha Frames

  10. Step 3: Isolating the Hydrogen

  11. Step 4: Combining Hydrogen with the LRGB

  12. Final M82 image

  13. Details of the Combining Process: M101 Standard LRGB initial image

  14. Raw Hydrogen Data 4h

  15. Extracted Red Channel from LRGB

  16. Subtraction of Red from Hydrogen Data

  17. Nearly Isolated Hydrogen Image

  18. Differentiation of Stars from Nebula

  19. Hydrogen Data with Stars Removed

  20. Final Image after addition to RGB Channels

  32. NGC 6822 – Barnard’s Galaxy

  33. NGC 6822 – Barnard’s Galaxy

  34. NGC 6822 – Barnard’s Galaxy

  35. M33 in Triangulum

  36. M33 in Triangulum in Hydrogen Light

  37. M33 in Triangulum Enhanced Hydrogen Image

  38. The Finally: M33 in Triangulum

  39. M33 in Triangulum with Enhanced Hydrogen

  40. 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
