sets of images acquired with K3CCDTools.
Further enhancements made
with Adobe Photoshop 7.0
- Aligned and stacked 17

- Gamma adjusted to 0.5
- Two sets aligned and merged
- Unsharp masking (1.0 pixels to 60%)
one of my first decent images of the Sun in Hydrogen
Alpha. Gave up on trying to obtain disk details and prominences
in one set of images. Took one shorter exposure for disk detail
and a longer exposure for prominences. Notice the two large
sunspots with their dark umbra and surrounding penumbra.
