The Pleiades (M45)

Somehow, I’ve never really captured an image of The Pleiades (M45). Such a bright target directly overhead, but I was mostly looking for narrowband objects instead, I suppose.

Pleiades final 8x10 crop

This image was processed entirely in PixInsight, except for the final rescaling and jpeg conversion.  I’m moving more in that direction. Frustrating and unforgiving it is, but powerful.  For such a bright object, the dust makes it more challenging to process than I’d expected.

Image data:

  • Exposures: 20×10 min L (1×1 binning), 8×10 min each R, G, B (2×2 binning) – total exposure time:  7h 20m
  • Telescopes: Two William Optics Star71s (360mm f/5)
  • Cameras: SBIG ST-8300M and QSI 583wsg
  • Mount: Takahashi EM200
  • Guiding: QHY 5L-II mono, guided using PHD2
  • Conditions:  fair transparency, calm winds
  • Processing: DeepSkyStacker -> PixInsight
  • Date: Jan 2, 2016
