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

Пример подавления

An example of the suppression of the “grid” in the image.

First Jupiter this year. At the time of the shooting, the height of the planet was about 20 degrees. At such a height, dispersion begins to interfere, and a stable atmosphere is more difficult to catch. From 20 seconds to 90 seconds, only one good.
