Hi @rwg0 Can u pls provide an example, how to convert image data from FITS file to a [System.Drawing.Bitmap](https://docs.microsoft.com/en-us/dotnet/api/system.drawing.bitmap?view=netframework-4.5) image? Example input FITS is available [here](http://nova.astrometry.net/new_fits_file/1493115) which I can open/import in [Gimp](https://www.gimp.org/) and it's a color image with 3 axes. BR, Ladislav
