I just started using Voytager, with a OSC (ASI2600mc) camera. When I run the Weighted Batch PreProcessor script in PixInsight, I get a warning below:
** Warning: Invalid file name characters will be replaced with underscores in filter name: '** BayerMatrix **.
The script complains about the " ** " in the filter name in the fits header. In the file name, how do I replace that with something else like an underscore so the " ** " is not used in the Fits header of the file.
