Ok, thanks.

Disagree. Context is visibility of asteroids 'inside' Earth's orbits, not of planets. Makes zero sense in context. /1

There is no cutoff to visibility at Earth’s orbit. (What Myhrvold said Mainzer said.) Are you saying there is?

for small (faint) the sky brightness (background) also scales up >> signal to noise plateaues. Thus planets irrelevant. /3.

LSST claims it can detect asteroids closer to horizon and has done simulations showing that. Yet to be demonstrated in practice.

My point is Venus is irrelevant in context because seeing planets and asteroids are not comparable, by many orders of magnitude.

Besides, this Venus pt has nothing to do w/ the new paper. This is Nathan's March PASP published paper that passed peer review.

Curious: did you even look at that paper? Here http://arxiv.org/pdf/1506.07085v4.pdf … or http://iopscience.iop.org/article/10.1088/1538-3873/128/962/045004/pdf … ? Search for the word "venus".
