Winter Astronomy Photos shooting

I had been to the Bignor Hill for the winter shooting at 2 Jan 2025. The sky was very very clear. And I had a chance to shoot Orion. It would only possible to be seen in the UK winter. The most challanging stuff is the freaking cold weather.
The photos are just using basic histogram to process.

My previous company was in this culture. It works very well. But it is a small company. So, I don’t think a large enterprise would work as most of the large enterprises are very hierarchy and bureaucracy, full of politics.

This is the RAW of M31. No coma corrector, so the stars at the edge are in oval shape.
