I think you'll find that the well depth is around 25000 e-, or electrons. The gain is normally set so that full well is around 65000 ADU (approximately the biggest unsigned number that fits in 16 bits). It's typical to target 30-40K ADU for flats.

Whatever processing software you decide to use should have this capability. You might want to investigate some more powerful capture software that can do it too. I use Maxim for capture and PixInsight for processing and both can do this but, Maxim at least, is relatively expensive and may not suit someone starting out.

Cheers,
