Thanks--sorry it took so long to respond.  What you ask for is a daunting task.  Capture includes Maxim DL, Cartes du ciel, manual framing, manual focus, using SFS to verify FWHM, eccentricity, median,SNR, etc.  As far as processing I align using default settings (drizzle if I have enough data which is uaully not the case-besides, I like Mure Denoise ), integrate usually with WSC.  Then I do the following in order
1_ Mure Denoise
2. Dynamic Crop
3. DBE
4 Photometric CC with Background Neut (for LRGB)
5. Insert Ha into red and Lum using Vicent Peris tutorial
6. Manual Hist stretch of RGB and Lum
7. RGB working space. (.333 to each channel)
8. Linear fit extraxted lightness layer to lum
9. Reinsert Lightness using Chennel combination
10. Insert Lum using LRGB tool

Then I start processing, which procedds over many days if not weeks untiol i am satisfied, which sometimes never happens.
