Pixinsight Work Process Flow Chart

Hi Adam,

I really never regret my purchase of the Fundamentals course and appreciate the numerous updates you provide.  However, I am wondering if my work process needs updating since I like working on a starless and stars image separately.

There have been so many new developments for Pixinsight users recently using starless and stared images..  Russ Crowman's BlurXterminator, StarXTerminator, NoiseXterminator, and Bill Blanshan's Star Reduction and Reduced Stars are now part of my workflow.  Would you mind commenting if the attached flow chart has any major errors?  I am assuming I have completed creation of my final image up through WBPP.  I know there are many side shoots off any given process but was just wanting to get some recommendation on how these scripts might affect things.  I am assuming one would want to work on a starless and stars image as separate images.

Thanks for your input.

    Hi Mike,

    SCNR after DBE is a little wonky. I would move it to after SPCC if you really need it at all. SCNR before SPCC will definitely change the color of stars and SPCC will have a more difficult time doing its thing (I would expect your resulting plots to have more spread/errors).

    I think the LHE *and* MLT is a bit much for most purposes..but that is me. 

    I personally use NXT after the image is non-linear (once) unless crazy noisy.

    "Star Reduction" can be part of the Stretch of the stars only image. You do not need to stretch as much..and thus benefit from a thresholded (naturalish) small starred image.

    Hi Adam,

    Thank you for the feedback.  Good suggestion on the star reduction on the stars only image.  One question.  Do you use NoiseXterminator after BlurXterminator as well or just once on the starless image?

    BXT always comes before NXT.

    For most images if I was using BXT I would apply it to the image before I removed the stars- so that the stars only image will have the benefit of the deconvolution as well as the non-stellar features. BXT lets you control how much sharpening is done to both- so there isn't a downside to doing this before SXT (star removal).

    In other cases- there are times where the stars of image are not used (and come from a different source. In this case, just doing BXT on the starless image makes sense.
