UPDATE |
OTA's clamshell rings are now complete, as shown in
this recent photo to the left. The dew shield is shown attached
as well. |
|
The rings themselves weigh 2/3rds of a pound, 1/3rd
of a pound for each ring. |
|
Testing of this OTA will begin the week of May 23rd
on a Paramount ME. The bolt pattern at the bottom of the rings
mates to the dec plate of the ME. The top of the rings can accept
further accessories/equipment. |
