M45, shot in RGB over several nights in late November/early December 2024.
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, which jump out a little more when you look at the starless revision
Per-filter totals for Pleiades:
- Red : 7.00 hours (84 subs)
- Green : 6.83 hours (82 subs)
- Blue : 7.17 hours (86 subs)
- total : 21.00 hours (252 subs)
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
