Hi, I am trying to load the data from a fits file using the FITSIO package and view it with using the image command. Is it possible to implement "zscale" equivalent of ds9 using the image command? thanks

Greetings! I am still new to R but have been asked to look at doing astronomy with R. I have a FITS file which contains an optical telescope image (it can be viewed in SAOimageDS9). I need to estimate the magnitude of a galaxy... and eventually other optical sources. How do I find the apparent magnitude of a galaxy from a FITS file? -- View this message in context:
