Just yesterday I wondered why there's never been a sci-fi planet near a globular cluster (that I know of), to have a spiky fuzzball of pinpoints of light, about the size of the moon, rising over an alien ocean.
Maybe even not as large as our moon, but enough to be able to make out its' intricate features with the unaided eye.
I wonder how such a sight in the nighttime sky would affect the worldview, mythologies and development of science, in primitive technological cultures, say in their paleolithic or bronze phases.
NGC 5634 is a globular cluster about 80k lightyears away from us. It's pretty small compared to other globs like M13. I only spent an hour on this while waiting for other targets to come up the last time I was at a dark site. Captured on June 7th, 2024 from a Bortle 3 zone (Deerlick Astronomy Village)
duplicated each image and removed stars via StarXterminator. Ran DBE with a shitload of points to generate background model. model subtracted from original pic using the following PixelMath (math courtesy of /u/jimmythechicken1)
$T * med(model) / model
Luminance:
BlurXTerminator (correct only mode)
ArcsinhStretch + histogramtransformation to bring nonlinear
RGB:
ChannelCombinaiton to combine monochrome R, G, B stacks into color image
BlurXTerminator (correct only mode)
SpectroPhotometricColorCalibration
HSV Repair
ArcsinhStretch + histogramtransformation to bring nonlinear
Curves to saturate it a little
Nonlinear:
LRGBCombination with stretched L as luminance
DeepSNR Noise reduction
Invert > SCNR > invert > SCNR to remove some greens and magentas
Several CurveTransformations to adjust lightness, contrast, colors, saturation, etc.
