          'enabled' => string 'yes' (length=3)
      private 'valid' (ElggExtender) => boolean false
  1 => 
    object(ElggAnnotation)[1145]
      protected 'attributes' => 
        array
          'id' => string '21706' (length=5)
          'owner_guid' => string '28715' (length=5)
          'access_id' => string '2' (length=1)

      private 'valid' (ElggExtender) => boolean false
  2 => 
    object(ElggAnnotation)[1146]
      protected 'attributes' => 
        array
          'id' => string '21707' (length=5)
          'owner_guid' => string '40468' (length=5)

      private 'valid' (ElggExtender) => boolean false
  3 => 
    object(ElggAnnotation)[1147]
      protected 'attributes' => 
        array
          'id' => string '21708' (length=5)
          'owner_guid' => string '28715' (length=5)

          'time_created' => string '1406104062' (length=10)
          'enabled' => string 'yes' (length=3)              
      private 'valid' (ElggExtender) => boolean false
  4 => 
    object(ElggAnnotation)[1148]
      protected 'attributes' => 
        array
          'id' => string '21709' (length=5)
          'owner_guid' => string '40468' (length=5)
          'access_id' => string '2' (length=1)

$unique = array();

foreach($objects as $object) {
    $unique[$object->owner_guid] = $object;
}

var_dump($unique);

@RIADev $unique will contain 1 object per owner_guid, you can get the unique owner_guid by array_keys($unique)
