the TAL 100 RS (4-inch refractor), using a 10mm Vixen Lanthanum eyepiece (100x) I did not use any other filters than the Baader Kontinuum. The first three images are stacked out of 15 originals (1600 x 1200, f 5.1, 1/500s, ISO 100) using Keiths Image Stacker. Both images where processed with image processing software (unsharp masking, contrast +15, and resizing). The fourth image was stacked out of 35 images (1600 x 1200, f 5.1, 1/30s, ISO 100).

In the first image I left the original colour (green from the Kontinuum filter), in the second image I converted the first image into greyscale. The third and fourth image are in original colour again. For a first result, they look very promising. On the first image, a hint of granulation can be seen. Also notice the sunspot on the suns limb.

25mm Vixen Lanthanum ( 80x ) with a Baader contrast booster and a Baader IR/UV blocking filter attached to it.  The images where shot with the Nikon Coolpix 4500 at maximum resolution (2272 x 1704). Both images are stacked out of 5, using Keith’s Image Stacker. On both images I used unsharp masking.

The first image is an overview image of the Sun (Exp. 1/250s, f 3.0, ISO 100)

The second image shows the sunspots more detailed (25mm eyepiece, but with 4x optical zoom from the Nikon Coolpix (Exp. 1/60, f 5.1, ISO 100).
