Marks showing hourly intervals on the edge of the Star-finder white disk is often handy to have when do sight planning. This task can be simplified if you drill small holes along the edge of the red overlay at every 15 degrees starting at 15 degrees. I drilled this pattern of holes to the 180 degrees mark. Once the initial LHA of Aries is marked on the white disk, just put the red overlay on the white disk, line up the 0 degree mark with the initial LHA of Aries, and mark off the hourly interval through the holes.
