Nice DSO image with AO
Many large telescopes are necessarily equipped with Adaptive Optics to be able to achieve their theoretical resolution according to Dawes' limit. AO limits the FOV to a rather small area because it is impossible to correct wave fronts that arrive from a wide range of angles. Most of them are meant for exoplanets. I always wondered how they would perform on DSOs .
Well today I ran into this nice image, https://scitechdaily.com/crystal-clear- ... cs-system/ . That's pretty good resolution! TheFOV is about 2' diagonally, which is small but the resolution is quite good considering a garden variety 8" scope would have a resolution of about 1", which is the resolution obtainable by any scope without AO on an average night. Clearly the resolution is at least an order of magnitude better. This one is 8 m in diameter.
Nice to know thatAO is not just for exoplanets. Maybe there are lots more DSO images by large AO based telescopes over a wide spectral band, I just haven't seen many of them. Whatever, it's a fantastic image.
