Description

Sun as seen of today, 09/07/13, from Pisa, Italy.

These images that can be seen are taken photographing the projection of a Konus Refractor onto a white screen, and then elaborated with PS and LR (filters in various tones).

In the first one (selenium blue) are visibile the single cores of the various sunspots (groups AR 1787 and AR 1785). Instead, in the b/w one and better in the sepia tone filtered one the surroundings of the same cores begin to show more and more, even with the same initial captured data.

Shot Data: ISO 100, f4.0, 1/250" exp.

Processed with PS and LR.
