Paltry M42 Mk II
Hi all,
I decided to try a different method tonight. It looks pretty much the same, but is a bit more crisp.
I followed a tip that JohnH posted yesterday; the advice was that of Jerry Lodriguez on the Astropix site. Instead of Screen'ing all my individual layers together, I added them as Normal but at 50% opacity. This has the effect of averaging I believe. And, the more images you stack this way, the less noise.
Once all images were added as Normal @ 50% opacity, I flattened the image. I ended up with five images for each of the five ISO's my camera shoots at. I then added those five images together via Screen. Again, I've used gradiented layer masks to bring out detail in the Trapezium. This time, you'll notice the four stars are visible (I can actually see five when I'm zoomed in at 1600x in Photoshop when registering the large resolution images), and the dark cloud in front of the Trapezium has a lot more structure and form to it than last time.
Thank you to everyone for your kind words of encouragement. I really appreciate them -- I wouldn't be up at 5 AM, otherwise!
Regards,
Humayun
