SUMMARY

The discussion highlights advancements in ground-based astronomical imaging achieved by a team utilizing a zero read noise CCD and advanced digital signal processing (DSP) techniques. This innovative system captures a series of short exposures, selects those taken during stable atmospheric conditions, and combines them to produce high-resolution images. The results demonstrate a significant improvement in image quality, surpassing that of the Hubble Space Telescope.

A little plug for my supervisor and former group.
After a couple of years work with a very clever (zero read noise) CCD and a bit of clever DSP programming they now have a system which takes a sequence of very short exposures, picks the ones in which the atmosphere is frozen to give an undistorted view then add these frames to give a deep detailed image.
