Tried shooting in Lucky Imaging mode, 3-second exposures, total integration time nearly an hour, stacked on the fly in SharpCap 4.0 (64-bit) with dark subtraction.
Processed in PixInsight and Photoshop.
Gain: 4773
Mode: LGG
Temperature: -20°C
There's this approach called Lucky Imaging, where they take exposures of just 1 second each and shoot for hours. To avoid accumulating hundreds of millions of files, they stack the frames in real time, usually with rejection of blurry frames, so the final image isn't blurred by the atmosphere.
