UNUSUAL IMAGES

Hi guys,

I fixed a bug in 32-bit versions in 1.4.304 that caused the issue you're seeing.
Thanks DANI also for sharing your data.

As Che points out, it appears your data is stretched (as well as color calibrated). You would really benefit from flats as well - there are numerous dust specks on your sensor. Assuming you're using DSS, try stacking with these settings. Make sure you don't apply stretching - to check whether your data has been inadvertently stretched, compared it to Autosave.fts - it should look the same.

Let me know if this solves your issue!
