Full Moon - Stacked
Oct 31, 2012

I was fortunate enough to have clear skies for the full moon so was able to take some shots to practice stacking.

These were taken on a NEX-7 at ISO 100, 1/320sec exposure using the continuous shooting mode which takes 10 frames per second. Although fired by hand rather than with a remote I don't think camera shake was an issue given the high shutter speed. I had 56 shots in total.

Processing steps were as follows:

Photoshop Elements 10: Each photo was cropped to 3200x3200 with the moon in the centre (Registax doesn't like the moon moving around the frame too much) and had Auto-Levels run to bring up the brightness.

Registax:

  • Load the 56 images
  • Use "Set Alignpoints" to let Registax choose the points
  • Align, limit (53 frames were chosen automatically) and stack
  • Set Wavelet parameters to: 9.7, 4.8, 2.4, 1.1, 1.1, 1.0
  • Set Gamma to 0.7

Below is the result plus a comparison with the sharpest frame (unprocessed) from the original jpegs.

Registax: 53 frames taken as ISO 100, 1/320s
