So following that reasoning, if I make my 1000mm scope effectively a
2000mm one by using a 2x barlow, I would get better resolution. I also
presume that you could keep going until the object becomes too dim to
image properly. That seems counter-intuitive, as we all know that the image quality drops away as the magnification increases, or is one supposed to use lower and lower power EPs to keep the target's apparent size unchanged.
Would that mean that a 2000mm scope using 20mm EP[100x mag]
would give a superior image to a 1000mm scope using a 10mm EP[100xmag]?
