Cons: Central rod tripod support needs a good deal of tightening to lock the binoculars in place, there\'s considerable visible blue CA on both day and night use, useful objective diameter a little smaller than 80mm

Pros: Sharp image, great contrast and luminosity. Low scattering and very few internal reflections. All visible surfaces from the outside are MC. Build quality is good.

Summary: Bought these secondhand, this exact same model was imported to Brazil by Lugan and branded as \"Lugan 20x80 wp\". Since I\'ve bought them, they have become my favorite pair for stargazing. They have very low scattering and few internal reflections and despite a somewhat bothersome CA on very bright objects, even the weakest stars appear as pinpoints on the center of the view. There\'s what appears to be defocusing in the ~20% outmost field of view, but it isn\'t distracting under day-to-day use. Exit pupils are round and have uniform luminosity, also under the flashlight test their effective aperture seems to be about 77mm. You can use it with glasses but you\'ll need to press them on the eyepieces to get the full FOV. For terrestrial use, the CA is more evident, mainly when observing treetops in contrast with the sky. Colors are saturated and the image is sharp, showing good details. For night use the few internal reflections are very manageable. On an overall, despite not being perfect, they\'re great for both day and night use, having an image quality better than the entry-level and japanese vintage binoculars I have used. The binoculars I found that are most similar in image quality are the soviet FMC 7x50 БПЦ Tento, which are also great. Furthermore, when those 20x80 binos are aimed at the sky supported by a steady tripod it always gives the \"Wow!\" factor for first-timers (me included), which is quite amusing on its own.
