Bill Tschumy created a new topic ' Statistics of region of interest' in the forum. 1 year ago

I primarily do variable star photometry. When planning my images, I need to adjust the exposure duration so the star in question (and the comparison stars) has a large enough SNR but also make sure they are not saturated.

The FITS viewer has a "Statistics of region of interest" feature, but it seems to only show the "average mean, average standard deviation and average median of the selected region". It would be really great it it could also show the Max value within the region. That would allow me to easily check for saturation. Currently I have to save the file and open it in a different app to check for saturation.

Perhaps there is already another way to check for saturation. If so, could someone explain it to me?
