Photography

all in pixinsight

1) stack the images separately (along with special calibration images)
2)remove the background (basically neutralizes any gradients from stray light and general sky glow
3) noise removal
4) merge teh images into an HDR
5) deconvolution (basically like sharpening)
6) color correction. basically adjusts the white balance according to teh actual spectroscopic view of the target)
7) deconvolution a second time (the pixinsight process I use does it in 2 steps when you use teh spectroscopic color correction)
8) stretch the image. basically brings out the nebula from the background.
9) I use whats called hdr multi scale trarnsformation which is a pixinsight process that can enhance details in teh nebula
10) curves transformation to bring out more color from teh nebula
11) whats called scnr in pixinsight to remove a greenish color cast that appears in a lot of images since teh sensor in a dslr is more sensitive to green

then i move the image to photoshop
1) curves adjustment to enhance contrast
2) camera raw for final tweaks
