The AP is about as heavy as the TeleVue. Every 2" diagonal tends to be
somewhat heavy, with the mirror being the heaviest part. The TeleVue
is designed straight, while the AP is a little piece of art, with nicely
smoothed corners, f.i. The locking screw of the TV is not to be recommmended,
but the screw/locking ring combination of the AP is far above the (american,
sorry ;-)) standard.
The MaxBright coatings are not only brighter, but also more durable.
