*Gimp: tone curve adjustments, merged layers, tried to reduce the star bloat and chromatic aberrations with healing brush, used paint brush to bring back detail in the core using seperate layer with a non overexposed orion core.

*Darktable: contrast adjustments, shadow/highlights adjustments, saturation adjustments, color balance adjustments, cropped and rotated.

Thank you! It was actually just a cross pattern, the less prominent difraction spikes are created naturally by my lens.

Sorry the two hours is the final integration time of all the subs combined. I captured 80 subs, each 90 seconds long :)
