My first shot of the Sun in the new 2019. The chromosphere is fairly calm, but there are several large prominences. Shooting was slightly disturbed by the dust in front of the matrix, I decided to unscrew the Ir-cut filter and was surprised to find that the brightness rose noticeably, as well as other dust particles appeared. The conclusion is strange – Coronado “flows” at IR. This feature requires more careful research. For the rest – no surprises, the camera still gives out a striped pattern, which was eliminated by the settings of the wavelets in Registax. I tried to shoot with Sky-Watcher Adventurer mount, approximately setup the polar axis. It is quite possible to shoot, only inconvenient without the remote.
