Messier 7, sometimes called Ptolemy cluster, is an open cluster located in between constellations Sagittarius and Scorpius. The cluster is visually located on the galactic plane of the Milky Way, therefore there are many stars in the background. The cluster is badly visible from Central Europe. Much better opportunities to observe or photograph this cluster have astronomers or astrophotographers in southern countries. My last attempt to capture it in Grease was constantly disturbed by the weather, therefore we I was again in South, specifically at Fuerteventura, I didn’t hesitate and recapture this beautiful cluster.
