Messier 45 with Olympus E-M10 MkII and 45mm f/1.8

[Guest]

Pleiades Open Cluster, aka M45, with an Olympus Om-D E-M10 MkII and 45mm f/1.8.

Shot in a Bortle 5 sky, untracked footage, in a humid and cold night.

4 seconds exposures at ISO 3200 and f/2.0.

 

Stacked and processed in PixInsight (WBPP, ImageIntegration, AutomaticBackgroundExtractor, BackgroundNeutralization, ColorCalibration, MultiscaleLinearTransform, HistogramTransformation, LocalHistogramEqualization, MorphologicalTransformation, CurvesTransformation).

 

545 lights, 55 darks, 70 biases and 70 flats.

 

Even though the short focal lenght (the camera has a crop factor of 2x) and the cromatic aberration, the star cluster is easy to spot.

Have you got any advice about processing or gear?

Oh well done with this untracked image!  Some nice reflection nebulosity starting to appear as well
