I was just wondering if any of you guys knew how to calculate the limiting magnitude of a 12-inch telescope given that you know the limiting magnitude of a 16-inch telescope.
I'm using the same exposure time obviously and I'm using an SBIG ST-4 CCD camera so these factors are constant. I just don't know how to scale it down for a 12-inch and it would be nice to know.
Thanks for any advice
