    Lights: 461x180sec (~23 hours) Darks:20 Flats:30 Bias:100

    Bortle:5 80% moon

    Scope: Rokinon 135mm (f2.0)

    Camera: ASI 585MC Air (cooled to -20C)

    Filter: Optolong L-Extreme

    Mount: IOptron Gem28

    Processing:

    * Sirl manual stacking with a linear fit clipping to help prevent gradients from imaging across multiple nights with a nearly full moon. Also stacked with a noise weighting

    * GraXpert background extraction

    * Spectrophotometric Color Calibration

    * Siril Aberration Remover Script

    * GraXpert Denoise

    * Star removal using the new SyQon Starless script. I had some artifacts from this so I decreased the tile size and increased the overlap and it worked better.

    * Hubble Palette from Dual Band OSC script (Improved HOO setting)

    * Statistical Stretch

    * HDR_Multiscale Script

    * Veralux Revela adjustments

    * Saturation Adjustments

    * Star Decomposition

    * Cosmic Clarity Denoise and Sharpen
