Issue with Astro Pixel Processor: Mono images from ASI183MM-Pro treated as RGGB Bayer images


Recommended Posts

For some reason, while FITSwork and GIMP read the data as mono, APP insists on interpreting them as OSC colour images with RGGB. While I know OSC camera data which are accidentally seen as mono can be forced to the correct Bayer pattern, the reverse is not obvious. I did get one batch to process correctly, but the second set of images refuses to be treated as grey scale, so I cannot neatly merge the data. What is going wrong?

I have noticed there is a bayer pattern "RGGB" item in the FITS header. The culprit here is APT, which defaulted the new camera to RGGB. I think I have sorted that out now. Having said that, I did at some stage manage to turn the previous batch of data into being interpreted as mono, so I am not sure what is different now
