Photographer's Note

This is not really an "earth" photo :) but as I mentioned in my intro, I also practice astrophotography so I like to share a serie of photos of a moon eclipse.

This was the total moon eclipse of 1996 as seen from the Netherlands. I took a serie of 24 photos of the eclipse and "summarised" it in these 7 phases. The total elapsed time from left (full moon) to right (full eclipse) was about 2 hours.

For this purpose I removed the lens of my camera and I used my telescope (with primary focal length of 1200mm) as a giant zoomlens (with a special adapter). The resulting magnification was 24x. To compensate for the rotation of the earth around its axis, I used a special motor to have my telescope mimic the earth's rotation, so the moon remained stationary in the view. Without this compensation, all photos would become blurred at this high magnification.

The colors are natural, no adjustments made. The red color was caused by the earth reflection of sunlight onto the dark part of the moon (similar effects during sunsets). With the naked eye this red color was very faint and had a "rusty" color. I increased the exposure times from phase 5 to capture this red glow.

Exposure times:
Phase 1, 2, 3: 1 sec
Phase 4: 2 secs
Phase 5: 4 secs
Phase 6: 6 secs
Phase 7: 30 secs (full eclipse)
