Canada's CHIME radio telescope is a unique design which is discussed at some length in this answer. I a comment below the question there I link to a question (presumably of mine) titled How does Canada's radiotelescope CHIME manage polarization-dependent apodization of the fast f/0.25 optics? but the link is now broke. I think that suggests the question had zero votes (or at least no up votes) and perhaps little activity so some SE bot deleted it. Not checking my recently deleted questions frequently enough, it eventually moved beyond my personal event horizon.
Is there any way to recover this question or at least the text thereof, perhaps with moderator help? I promise to spell "radio telescope" as two words this time!
