Orion redux

Here is another go at M42, taken two nights later. In this case I dropped the exposure of the individual frames down to 5 seconds, which has helped reduce the over-exposure in the core of the nebula. However, I would still need to drop it a bit further. Here I took 29 sub-frames and again combined them using Nebulosity. There are still a few bits of electronic noise in the final image. It was a race against clouds again last night, or else I would have taken substantially more sub-frames.
