Yes I have seen those visual representative type images before, has anyone ever done them for real, from an imaging point of view, with different size telescopes to show what the difference actually is?
So say I had a 6" F10 and a 12" F5 both would have the same focal length and image scale. It would take heaps longer to gather the same number of photons on the 6" due to the low F number. Would they both produce exactly the same image if you gave them different length exposures to account for the smaller aperture or would the bigger telescope have more detail and win the day?
This review of the 12" RC is definitely part of why I am asking this question. The current wisdom says a G11 won't carry the 12" but I have heard of C14 tubes on the G11. So is there any advanage going for a 12" rather than a 10"?
