Pleiades (M45) has some dark secrets

less than 1 minute read

I was able to pull out some darker whispies as well as several galaxies hidden in the mist while imaging Pleiades, AKA M45 or “The Seven Sisters” (I count a lot more than seven!).

This is 21 hours of RGB with pretty basic processing. There are also a bunch galaxies hiding in plain site

The processing included (see the processing icons here):

  • RGB combine via pixelmath
  • Auto Linear Fit
  • GradientCorrection
  • BlurX (correct only)
  • ImageSolver for SPCC
  • SPCC, set up for my astrodon RGB filters and PhotonFlux
  • BlurX Full
  • NoiseX
  • StarX
  • Stretch stars via STF/Histogram Transformation
  • GHS and a bit of curves to stretch the starless
  • put the stars back
  • final tweaking
