Thought someone out there would find this arrangement interesting, if not useful.
I use two 0.7 X conversion lenses for temporarily attaching over the objectives of a set of 7x35 mm wide angle binoculars. The best ones binos I have now, ones which afford generous eye relief is a vintage set of Jason 11.5 degree Statesman. (Today I was outbid on two pairs of Rangemasters.) The 0.7 X converters reduce the Statesman down to 4.9 power, perfect for seeing the entire stage from my seat in the nose bleed upper balcony of the Lyric Opera here in Chicago. Last week with monopod attached I saw The Barber of Seville. The best opera experience I have ever had. Obsolesces and eBay have made such conversion optics affordable. True, I can’t call this arrangement, a sort of a reverse barlow, ideal. Eye placement is tricky until you get the hang of it. I have not tried the fixed focus Bushnell 5 X binos. My guess is I would not like them. And I doubt their FOV would be wide enough.
Here are two pictures of my setup with 0.7 X converters. I don't trust the velcro completely. A plastic cable tie (not shown) goes around the end of the straps to surround each converter. The groves in the velcro pads shows where the cables were. I admit this is a very crude arrangement. If I had the skill, a machine shop or a 3 D printer, I might come up with something better.
I also push glass and star gaze. Yet I have not tested this optical pairing on stellar sources. I don’t expect perfection. But for the opera it seems sharp enough.
