Description

13 x 600s L and 6 x 600s each RGB.
It was a bit windy, so tracking was not perfect, but it will have to do for the moment.

Since our Spring Starparty was cancelled due to the COVID19 virus I had to image from home.

Final processing with deconvolution, nicer star colours and better background.
