Noob astrophotography

[perchloratepenguin]

Shot with Olympus Pen Mini EPM2 that I modified to full spectrum with Olympus M.Zuiko Digital 14-42mm f/3.5-5.6
14mm, ISO 640, Shutter speed 8s, f3.5, Custom white balance
800 pictures stacked on Siril and touched up with GIMP

The coma is quite apparent

MWay core! Wonder what portion of the original frame is this crop. The upper left part looks free of the terrible aberration. Sometimes the apparent aberration could be caused by the software failing to register the stars due to severe distortions of the image. You may verify this simply by checking star shapes in individual exposures.

You may also want to check the alignment of the lens, or simply get a fast prime lens of better optics.

Hello! Yes, the M101 was taken in SG, but I'm planning on gathering data for a better shot in the near future (when the clouds clear).
