Sunspot group AR2396 – August 11, 2015

And another session with AR2396.

This time I had some good seeing conditions that allowed a better resolution over the Sun’s surface and better details in the main spot of AR2396.

The equipment used: 200mm F/5 Newtonian at F/20 and F/50, full aperture Astrosolar filter, ASI 120MM-S camera with Baader Green filter.

The images, both greyscale and colored:

The above images were acquired at F/20, while the one below, showing only the main spot of AR2396 was acquired at F/50.

The rather good seeing conditions (reaching 7/10 in some moments) allowed me to capture good images of the solar granulation around a few pores:
