Adam,
      I am collecting data on a TOA130 with ASI6200MM.  I want to drizzle the 2x2 LRGB and NB data and also use the NSG script to correct the gradient in my subs.   How do I do this??  

Thanks!!

    Good question.
    You need to purchase John's  module so that you can incorporate the normalization files.
    But... lets let @JohnMurphy answer this himself!

    I will creating a new update for NSG shortly.

    Hi Alan,
    To make NSG compatible with DrizzleIntegration, NSG needed to produce '.xnml' normalization data files. Unfortunately this was not possible from JavaScript. I have therefore created a C++ module, 'NSGXnml' which the NSG 2.1.4 script calls in the background to create these '.xnml' files. I charge £20 UK pounds for an NSGXnml license, which helps me support both NSG and PhotometricMosaic. You can find out more on my website:


    To use NSG and DrizzleIntegration:
    (1) Create an ImageIntegration process icon (the contents do not matter - all values will be replaced). This is needed due to changes made in PixInsight 1.8.9 to prevent NSG displaying ImageIntegration.
    (2) In NSG, select the ImageIntegration process icon in the 'Output icon' combo box.
    (3) Check both the 'Normalization data' and the 'Drizzle data' check boxes.
    (3) After NSG has finished, double click on the ImageIntegration process icon. Run ImageIntegration.
    (4) Start DrizzleIntegration, and add both the '.xnml' and '.xdrz' data files.
    (5) Proceed as usual...

    Hope this helps, John Murphy

    John,
         I have been experimenting with NSG on Pixinsight1.8.9.  I am running NSGXnml on drizzled data.  It does a beautiful job, thanks!

    That's great to hear. Thanks!

    I have an addendum question to this thread...

    I ran NSG on my images but did not place the generated files in the same location as my registered subs (and the generated drizzle files)... 

    Image integration ran, but now I want to go back and re-run image integration using the NSG processed files, but also the drizzle integration files.  

    How do I do that?  

    I tried - 1st looking where I put the .xifs and .xnml files - but Image Integration did not "see" any drizzle files (it will only look for .xdrz or .drz files)

    I tried adding the NSG .xifs and then the .xdrz files from my registration folder, but Image Integration could not match the drizzle files up with the subs from NSG.

    I REALLY don't want to re-run NSG again just to get Image Integration loaded correctly - the NSG run on 1400 subs took over 5 hours to run.

    Thanks for any direction you might be able to provide
    John D
