Primary focus magnification?
Hello all:
My name is Miguel, from Buenos Aires.
I have a question... is it right in formal optics to name "magnification" the below formula or "focal distance equivalent" of a camera attached in primary focus (without telescope ocular and camera objetive, of course) ?
I can find that on my optics books neither Google searching.
I read this on the web:

Magnification = Telescope focal distance / Camera "Focal distance equivalent"

I read this on the web:
"What is the magnification of my telescope when the NexImage camera is in the eyepeice barrel?
The NexImage camera is equal to the magnification of about a 5mm eyepiece. To determine the magnification of your image when using NexImage, divide the focal length of your telescope (in mm) by 5."
