Saturnian Challenge II - Encke’s division
Now as most of you have seen Saturn’s ring are a fine sight this year, and Cassini’s division - the black gap between the A and B rings - is easily seen with the rings nicely tilted.
But there’s another division which can be seen in good seeing - Encke’s division within the A ring. At 325km wide it subtends 0.8 arc seconds from Terra.
Visible in the MK91 at 300X, it will be a tough challenge for 8” - 12” scopes and will test your seeing.
There are other divisions too within the grasp of larger scopes but excellent seeing will be your real challenge.
So which divisions can you spot ? And with what scope ?
