I remember hearing a reference on an astronomy documentary stating at one image for a radio telescope took about 75 days to complete. Is this true? By logic, I would assume that Arecibo images would need the shortest exposure and VLBA images would need the longest exposures. Arecibo has the largest effective dish size, and a low resolution. VLBA has the highest resolution, and high resolution details are generally fainter unless an effort is made to look at the brightest things.
Re: What are typical exposure times for images made with radio telescopes?
