Notes: This is one high surface-brightness planetary! I imaged this with fog and high clouds interfering ... I even took some 0.3/0.4/0.5 second subs that showed the ring structure (but few stars). I ended up with 5 second sub exposures as a compromise to show some stars ...

View 200% crop. See one 0.3 second sub exposure (only reduced brightness via brightness/contrast); one 5 second sub exposure (no processing). See the Aladin Previewer SERC/ER/DSS2 image.
