Hi Astropy Experts! I have a question related to plotting with the WCS projection. It seems that the WCS object internally converts most units to their SI representation, so e.g. Ångström -> m. Is there any way to reverse this mapping when plotting so that I can straightforwardly make a plot in Ångström units?

Cadair If the coordinate system is one known to astropy I think that WCSAxes will do that for you.

Cadair I can't remember what it is tho

If you are using WCSAxes then you can change the units to what you want with
it is a little annoying that the units get converted, and it might be nice to have a WCS wrapper class that can preserve units....
