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

ISS, April 7, 2019, 19:28

I decided to try capturing the ISS with the QHY5III178m astrocamera. Prior to that, he shot on a SLR camera in single shots. To reduce the impact of turbulence, I decide to add a red filter NPZ. As before, the survey was performed with manual tracking. Yesterday I also tried to take pictures – quite successfully, but a little bit overexpose a picture. Today I have set a smaller gain, I left the same exposure – 1\1000 s. Alas, the SSD was quickly filled, so I did not have time to shoot the entire span. However, the result is positive. I will continue to hunt for the ISS.
