"Lucky imaging" is not a widely used technique in astronomy.

There was a major announcement on Friday using just this technique: https://www.gemini.edu/pr/gemini-gets-lucky-and-takes-deep-d... It might become more popular now.

Yes, I saw it, and that was the first time I had heard the term in my years of studying and working in astronomy. Most astronomical sources of interest are not anywhere near as bright as Jupiter. It can take hours of integration to even detect many targets of interest. The technique is simply not possible for 99%+ of astronomy work.

Did I use the word "often" in my comment above? Anyway, as an astronomer, I've heard about lucky imaging quite a few times - it likely depends what other astronomers you are exposed to. Of course, it can currently only be used on some bright targets, but it's a fascinating method. Similar techniques are also now being used at other wavelengths, such as for the LOFAR low frequency radio telescope.
