(Welcome to all the NASA APOD<\/a> visitors for today, 5th October 2010)<\/p>\n

The image here is the outcome of an idea that started last week, when I saw Maurice Toet’s 4 pane Mosaic<\/a> of Orion’s sword area, and realised that it matched almost exacty the area I imaged in Hydrogen Alpha at Kelling Heath a few weeks back. Maurice was kind enough to provide me with the TIF file of the mosaic, and I set to work in combining the two sets of data.<\/p>\n

Using Registar, PixInsight and CS2, and adding in some Hydrogen Alpha data as luminance for B33 and NGC2024 from Darren Jehan and Tim Jardine, the many many hours of trial and error produced the following image. It was an absolute joy to work on, and I am not sure it could be improved all that much without a major rework from scratch. It is one of those images that require a decently calibrated monitor, as my laptop screen shows it too light and salmon pink, while my decent screens at home and at work all show a vibrant Ha red in the background.<\/p>\n

The details for the image data used in this final version is listed after the image. I would like to thank Maurice, Darren and Tim for all helping this project by allowing me to use their data.<\/p>\n
