"The diameter of the eyepiece is greater than that of the objective. This helps to collect more light and gives a brighter image"
I thought that increasing the aperture of a lens doesn't increase the brightness of a virtual image. Yes, it will increase the brightness of a real image caught on a screen, but not a virtual image (I think) So how will increasing the diameter make the virtual image brighter?
