RA ring nut is now visible. There were some differences compared to the DEC ring nut
- The distance between indentations were 40mm instead of 36mm, so another spanner tool is needed.
- The RA ring nut had 3 lock screws on the outside, while the DEC ring nut had only one.
- The RA ring nut lock screws can only be accessed through the RA setting circle lock screw
hole (on the top), using the proper allen hex wrench.
