The Sun on June 23d.

It has been a while since the last time I posted a solar image here, so I thought it was about time. Especially since there were a few nice sunspots out this day. For the images white light images, I used an ASI178MM camera, attatched to a Williams Optics FLT98 telescope through a Lacerta Herschel Wedge. The exposure was 0.5 ms. For the closeups, I used a Televue Powermate 2.5. Processed with AS!3, Gimp and Irfanview.  For the H-alpha image, I used a Lunt LS35 telescope with the same camera. Some dust probably on the blocking filter, so it needs to be cleaned... Click on the images for higher resolution.
