Hi, Anyone experienced stars appearing as monochrome artefacts on importing the file into Affinity Photo on iPad? File - 32bit TIFF, after stacking in Deep Sky Stacker where image appears with no artefacts. If the image is stacked in ASIAIR Plus and saved as JPEG file, the stars appear correctly in Affinity Photo. If a TIFF file is first saved in iPad Photos, it appears correctly there, yet again stars appear as artefacts if a photo is imported into Affinity Photo from the picture gallery. Thanks, Alexander

Forgive my question, but what would be different in «astrophotography» stacking as compared to the existing stacking mode? And apart from stacking, option to open FITS files is a must if one to import images directly from the dedicated astrocamera.
