You can open FITS using the "New Astrophotography Stack" File menu option. Admittedly nowhere as convenient as a direct "Open" function, but it's a start and we all hope "Open" is soon to be implemented. Take a look at some of the Youtube videos on v1.9 to see how to use the "Astro Stack" feature

Thanks Kirk for the input, yes, seems OK as a workaround. Small question for all astroimagers; how important to you is having Affinity do actual FITS stacking, in that many capture programs, and DSS as well, do this before one actually wants to sit down and get into the image processing side of things, which may be days later. I guess it's handy to allow you to flip through and find the duds before processing. My feeling is that I would prefer to use something like Astro Pixel Processor (APP) to come up with a final stacked image, which can then be filed away to await image processing with Affinity when ready. But as usual, one man's meat etc........ or YMMV, take your pick. BTW, five FITS uploaded to Dropbox from QHY8 Pro, QHY9 Mono and ZWO183MC pro, plus a sharpcap snapshot. Mike

Thank you for the prompt response, and I would like to offer my sincere apologies for not delving further into Affinity before making my rant post below. Good to see you are making steps to bring FITS into the fold, hopefully eventually it will also function in the file-open functionality, as most astrophotographers have literally thousands of FITS files on their computers, and their comments, at least to me, clearly explain the need for a simple "file open" function. Again, thanks for bringing FITS capability on board. After coffee time this morning I will upload some FITS files to the Dropbox folder from my various QHY and ZWO folders, plus examples of Raw and processed FITS files from my various astro applications, including DSS, Nebulosity, N.I.N.A. and Astro Pixel Processor. Unfortunately these can be quite large, a few up to 80MB, so please feel free to let me know if you prefer not to have them sent. The intent is simply to allow compatibility checking with the widest variety of astro imaging equipment and software. Finally, my compliments on a very well designed website, very easy to read and use. Mike, Queensland, Australia

I use FITS exclusively in my astrophotography software. I watched numerous Youtube videos and reviews on Affinity before I decided to purchase, foolishly without bothering with a free trial. If I'd known that after two years on the market, you still have not implemented a FITS capability, I would not have purchased the programme. A real Caveat Emptor and I will be making sure all my astro friends here in Australia are made aware that Affinity doesn't do FITS.
