I just want to share this just in case someone had issues like I did with WBPP Local Normalization in Pixinsight.
The first time that I used LN in
PI I found that it really helped with background gradients and took a big load off of Dynamic Background Extraction.
I live in a light polluted area (
Bortle 7) and have lots of local (and more distant) light sources that cause me some gradient issues. Especially when most of the gradients disappear when the scope is aimed high.
I would have errors when running WBPP to the effect of “Failed to find LN reference frame” (going from memory, so I might have some wording off).
I searched high and low and found some solutions on the Pixinsight forum, but they mostly were relating to past versions of WBPP. I tried them anyway without success.
This was an intermittent issue. Sometimes it would run successfully and sometimes it would fail.
Finally, I found the fix (for my situation) on another
PI forum post. The fix was to enable long filenames in the Windows registry. Apparently, if the filenames are >260 charactors, LN would fail to find a reference frame. I certainly could not imagine that my filenames were longer than 260 charactors, but apparently they were (sometimes).
If you are have similar issues, there is nothing to lose by trying this fix. Of course, if you are not comfortable with editing the Windows 10 registry, you might not want to try this.
Follow the instructions in this article to enable long filenames in the Windows 10 registry.
I hope that this helps someone having this issue because Local Normalization is a wonderful tool.
