The Encke division (or more commonly "Encke Gap") was seen only near the vertex of the ring system - the best place to pick it out.
I did a quick google to find out what telescope Encke first observed the gap with but failed to find this out. I note some observers on Cloudy nights claim to have seen it in as small an aperture as 8" !!

I expect that many are confusing the Encke Minima with the Encke Division.
I have seen the Minima in several scopes and thought I saw a hint of the Encke Division in the TEC 200 Maksutov but couldn't really claim it .....
I have seen it for certain just once in each of my 18" Dobs from the rural skies near Coonabarabran. It really is very elusive. Trying again tonight....
