For my purposes, I just review my raw light frames BEFORE I put them into IP (Picasa's Photo viewer works well for viewing RAW CR2s) and look for subs that have obvious guiding errors, major airplane trails and other big issues. That it throws out more of my subs than I'm willing to sacrifice. The grading DOES work and is generally good to use. The grade box analyzes the images and decides which ones work best. Personally, I do NOT check the grade box. In the same section, check the normalize, align, and combine boxes. Next, in the Perform after calibration and color conversion section, check "minimize hard drive use" (this deletes the interim files and leaves you only with converted, calibrated files - if you want the interim files, do not check this box). Select a folder to save your calibrated files (I usually create one named "Calibrated Frames"). Do the same on the Dark Frames tab (obviously selecting your darks), Flat Frame tab, Flat Darks tab (if you have them) and Bias Frames tab. Go to the Light Frames tab and select all of your light frames. The basic steps I use for automated processing are: As I said, for my taste, the automated processing works and is easy. Mike Unsold may be able to elaborate as to whether there are reasons to use the automated versus manual processes. The automated image set processing ends up doing the raw conversion, normalizes the images, calibrates them, generates master dark, flat, and bias frames, aligns, stacks, and combines the image without hardly any user intervention. I don't know if there's any advantage to using your manual method, but it feels like too much work for my taste. ![]() I've always used IP's Image Set Operations | Automatic DSLR, OSC CCD, CCD Image Set Processing, as its completely automated and works extremely well. I see that you're doing all of these steps "manually". ![]() You have as your first steps Raw conversion, normalizing, aligning, stacking, etc. I haven't had a chance to review the entire document, but I took a quick look at the first section. Sorry, but I've been a bit busier than normal lately, so I haven't been able to keep up on this thread. On a side note, what are your thoughts about the new workflow process? It was put together in consultation with Mike Unsold as you know not sure if you had a chance to review it? Your feedback will be appreciated. From a different thread (Mike's Flaming Star Nebula Reprocessing):
