do wide field eps reduce bightness of objects
I wonder if someone who knows about optics could answer this question for me. Does an object viewed through a wide field ep show less brightness than one viewed through say a plossl? My curiosity is that if a the lens is limited by size, say 1 1/4", does the light get spread over a larger FOV thereby diminishing the light for each object in the FOV. To test this I compared some faint stars through my 9mm Nagler with the same stars with the 9mm plossl that came with the scope and they did seem slightly brighter in the plossl. Is this my imagination, the effect of fewer bits of glass in the plossl, reduced contrast because there are more objects in the FOV of the nagler or because the larger FOV means less light for each object. I love my widefield eps, but wonder if using plossls might be better for very faint objects.
