Like the M2 Mount, this column is made in the USA of 6061-t6 aluminum. The M2 mount head bolts to the top of the column with three side screws. This eliminates rotation between the mount and column.
Add the extension column only to the mount head.
• For mounting to Stellarvue Surveyor tripods using a 5/8-11 bolt, select the MEC002 column.
• For mounting to tripods with a 10mm bolt (Celestron CG5 mount / Vixen GP mount for example), select the MEC010 column.
• For mounting to tripods with a 12mm bolt (Celestron CGEM mount for example), select the MEC012 column.
NOTE: The column is made only for the M2 mount head. The head attaches to three holes at the top of the column. So the M1 mount will not work with this column.
