What's the highest resolution image of the moon taken from Earth? Presumably some stitched together image from one of the large telescopes?

- dylan604 2y agoNot presumably. The highest resolution image is a stitched together image. Depending on the magnification of a given telescope, you'd have to stitch multiple shots to see the entire surface from multiple shots depending on the particular telescope used. My personal telescope was purchased specifically to see deep sky objects without needing to do stitching; a wide angle telescope if you will. In my scope on a full frame DSLR, the full moon is less than 25% of the frame. This particular photographer stitched more than just enough shots to cover the full disc, but also from multiple phases which allows parts that would be in shadow during one night of imaging to be in full light during other nights of imaging. A "simple" mosaic of the full moon can be captured in a single night, but this guy said "hold my beer" and went nuts. Dedication doesn't even begin to describe
- exitb 2y agoIf we were to talk about hypotheticals, let's look at this picture of Io[1] taken from Earth's surface. Io's angular size is 1.2 arcsec. Feature of that apparent size would be ~2.2km in diameter on the surface of our Moon. With that kind of resolution it seems that you could map out features of 50-100m in diameter. Obviously though, no one will tie up one of the most expensive telescopes with a project of covering half of Moon's surface with that kind of pictures. A satellite would be a better tool for this job.
