Re: ATM weight of an eyepiece

Hi Patrick,

There is technically no "Nagler" 25mm. According to the manufacturer, the
Tele Vue Nagler 22mm Type 4 (82-degree apparent field) weighs 1.5 lb. The
Tele Vue Panoptic 22mm (68-degree apparent field) weighs 1.0 lb. The Tele
Vue Ploessl 25mm (standard 50-degree apparent field) weighs 0.3 lb.
