Hi All,
I have a photo of the ISS and i wanted to calculate its absolute magnitude and compare it to the predicted mag when the photo was taken
I've found the pixel value for a point on ISS and i have also found the pixel value for an identified star in the background.
How would I calculate the ISS absolute magnitude and apparent magnitude from the pixel values. I have the apparent/absolute mag of the known star.
thanks
