Some old data on M42

I had a set of osc data taken with a modded Canon and  a 150 PDS as it's first outing sometime ago  so the scope was uncollimated and had all sorts of issues. I also found some Ha data taken with an Atik 314L+ and a Zenithstar 71 @ F4.7 last year. I just combined them and did a bit of play in PS. Nothing to write home about but it beats getting mad because of this weather, just for fun. The osc data is quite weak in the blue for some reason and the stars are horrble. I think the osc data was 16 X 180s and have no idea what the Ha was for sure.
