Histogram/GHB Function Not Stretching Starless Image After Running StarNet++
Siril version: 1.2.0
Note: please report against latest git master branch or latest stable version
Operating System: Windows 10 Pro - 22H2
Package: 64-bit download from Siril.org
Description of the bug
When running stacked OSC/CCD images through StarNet++, the histogram and GHB stop functioning when attempting to use them on the resulting starless FITS. Each time an attempt is made to stretch, the data "snaps" back to the left side of the histogram no matter how many times it is moved.
Prior to running StarNet++, the histogram and GHB functions stretch without any issues.
Reproduction
Reproduction steps:
Process image using background extraction, photometric color calibration, remove green noise, deconvolution, and then open StarNet++ in SIRIL. Select generate star mask and pre-stretch linear image options before running the program. Run StarNet. Open GHB or histogram function, and attempt to stretch starless FITS. …
Expected result: A starless FITS that is able to respond to adjustments using GHB and/or histogram function.
Actual result: Image does not stretch.
Additional information
SIRIL doesn't give a warning or error message when the GHB/histogram fails. As well, I have not had this issue with stacked DSLR data, only OSC/CCD-generated iamges.
If it's helpful, these images are the result of stacking via SIRILIC.
