Advice on Horsehead processing please.

Hi,

I went to Astrofest for 5 days and had the best time. On the Wednesday morning I imaged the horsehead nebula and shot 14 x 8 minute ISO 800 with Canon400d unmod through W/O 110Flt and guided with PHD. Full calibration was done.

The issue I am having is when I boost my levels the main star really blows out so it consumes the image when the horsehead appears. I am really happy with my data but wonder if any processing tips could reduce this or am I stuck with this.

the first image is the unprocessed raw showing the star and a little one next to it and the second is the very quick processing job to show my blown out star.

Any advice welcome.
