Hi Austin,
When I open a FITS file directly in DS9, it only displays one extension by default. However, if I choose “open as mosaic”, DS9 loads all the extensions and displays the full mosaic.
The same happens on astrometry.net. It uploads only a single extension. I would like to upload the entire mosaic, so that astrometry.net returns the WCS file for the full image, which I can then use to update the WCS in my original file.
Is there a way to upload the full mosaic?

Hi,
Sorry, the astrometry.net web service only understands single-HDU FITS files. You will have to manipulate the FITS file to pull out and upload single HDUs.
Best wishes,
