Solarspot AR 2738, 17/04/2019, 10:57 (UTC +3).

Already the second day has no luck with shooting the Sun – solid clouds. For a minute I managed to catch the sun in a hole between the clouds. The spot AR 2738 is large, interesting, with a complex structure.

It was possible to significantly reduce the “grid” effect when shooting with a QHY5III178m camera. For this you need to use the program Fitswork, choose Processing> FFT> Automatic 2D filter

Sun in h-alpha line, April 3, 2019

In the afternoon, I captured the Sun a little in the line of hydrogen. There were practically no large prominences, however, there is one active zone NOAA 12737. Tomorrow I will try to capture this area in more detail.
