The Summer has arrived to an end…
But today, the 29 degrees Celsius, the no-clouds beautiful blue skies, and the large number of butterflies made me feel otherwise…
Together with my brother-in-law, I’ve went to my usual solar-imaging site, 6 miles south of home.
The equipment was the 14inch Newtonian, so I had (once again) hopes for a good image to match the large diameter of such a mirror. Not a chance…the seeing was again rather poor, with only a very few brief moments of 6/10 seeing conditions.
The following image shows sunspot AR2418, a solitary crosser of the solar disk.
Technical details : 355mm F/5 homemade Newtonian (SkyWatcher optics), 2.25x Baader Hyperion barlow, ASI120MM-S camera with Red filter, and Baader full-aperture solar filter at the front. Seeing: 3-6/10.
Notice the solar granulation and small details in between the granules, as also some small white-beads around the penumbra of 2418.
