Description

Picture taken in the early hours (1-3 AM) of Easter 2020.

The Kelda 135mm camera lens performed very well at F2.8 with just the help of the Fringe Killer filter to limit CA and possibly also SA.

Stars are envertheless not perfectly round because what is after all a cheap (90 €) camera lens cannot provide perfectly round shaped stars at F2.8.

They improve stopping down the lens, of course, but I wanted to collect the maximum quantity of light in the time I had available and I think the compromise is acceptable.

I am also quite happy that galaxy NGC3593 is clearly visible in the lower left corner.
