(Click for AstroBin card)

Cross Posted from System Build thread

I'd previously given up hope on this data, there's some HORRIBLE gradients (Unstretched TIF linked in the AstroBin card for those who wish to see). Rummaging around this morning for some data I hadn't tried in ST yet (it appears I'll have time to try everything HST has ever shot in St before the weather clears) and decided to give this one a shot.

ST Log :
  • Binned 71%
  • Cropped 50 pixels off each edge.
  • Develop Gamma .94, DAF 5.3 pixels, all others defaults.
  • Wipe started with the Gradient preset, Precision 512x512, Aggressiveness 98%
  • Wipe again with the Gradient preset, to attack the 2nd gradient, Aggressiveness 95%
  • Basic star mask, unselected most of the core, inverted.
  • Filter, Reject mode, started cleaning up most of the gradient left in the lower left corner.
  • Contrast
  • Sharpen
  • Mask, Threshold 85, Highlights>Threshold
  • Color, Sample, Fill Mask, Saturation 125%
  • Stop tracking, Denoise defaults
Once tracking was off:
  • Created a Star mask, tweaked to split multiple star groups and deselect much of the core
  • Repaired with Warp
  • Magic Shrink Core
  • Color saturation 115%
  • Synth - Refractor - Adjusted to taste
