Very nice images. Did you mix several different exposure times?
i found that when I imaged M42 for the first time I overexposed the Trapezium at the centre of the nebula. I used all the same length of exposures. It came out as a white, blown highlight, so all I could do was darken it in photoshop.
They are watching us......
Yes it was about 9x60s and a mixture of about 20 others covering 5s, 15s and 2x30s at iso800 then processed in stacking and editing software called Pixinsight. It depends on how you like your image, rich and colourful but with the core blown out or more subdued showing the core. This is a slightly different edit of the same image as an example
Great images showing the "Sword" of Orion! I particularly like the one above. It reminds me of some of the sunset pictures showing the reddish rays of the low sun illuminating the Sunward side of a cloud. I notice one thing that doesn't affect the beauty of your image, but does affect its scientific accuracy. The image looks to be a mirror image of "reality". This is most apparent in the area I like to call the "Bird's Head", also known as M43. While it's part of the larger Orion Nebula (M42), it is the detached portion, which looks to me like a bird and its beak.
If an imaging system includes an odd number of reflections, like employing a star diagonal with a refractor, you will get a mirror image. I suppose if this is of concern, it can be changed easily in post-processing. Newtonian reflectors generally don't have this effect (uses 2 mirrors), but refractors and Schmidt-Cassegrains with star diagonals (1- and 3-reflections) will be mirror imaged.
In any case, congratulations on getting a spectacular image of M42-M43! Thanks for sharing.
