sergio created a new topic ' FITS Viewer and star ADU' in the forum. 2 years ago

Once the image is captured I would like to measure the star ADU to set the CCD exposure time. This is needed to avoid saturated star for the exoplanet measurements. In fact when the image is displayed in the FITS Viewer, I can read the X,Y coordinates of mouse pointer and other info in the bottom bar, but it is missing the pixel values. How Can I extract this star value ?
