2. ENHANCED HYDROGEN GALAXY IMAGING By Chris Schur

3. Introduction n What is Enhanced Hydrogen Imaging? n 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 n Additional acquisition time is minimal n Tremendous Visual Impact with small additional effort n The Process Revealed …

4. Process Example: Standard LRGB NGC2903

5. Process Example: Enhanced LRGB NGC2903

6. The Process: An Overview n First make a standard LRGB n Take additional Ha frames n Subtract Red data from Ha data n Add difference to Red, Green, Blue n 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
