M38 - The starfish cluster
Initially taken as a check to see what I could have from Paris' suburbs heavy LP skies for a star cluster, considering that kind of object should be easier than nebula or galaxies in that kind of sky. Turned OK but I still have difficulty recognizing the starfish shape when zoomed in, I need to zoom out quite a lot for the shape to become obvious.
Gear: Olympus E-PL6 on Skywatcher 130PDS 632mm/4.86 at F/4.55 with SW Coma corrector and Didymium filter on Celestron Nexstar SLT.
Capture: 12 lights x 20s x 1600iso, master bias and (synthetic) flat.
Software: Regim 3.4, Fotoxx 12.01+
Site: 20km from Paris France; Clear sky, relatively good seeing, SQM 16..17
