I have a seldom used 20x80mm bino for sale at S$150.
It is similar to this one which is selling for US$229:

The bino I have is branded as Oberwerk but I'm not sure whether it is exactly the same thing, bec Oberwerk has changed their product range.
It is stated to be "Fully Multi-coated" and having "Bak-4" prisms. However, I would say from the looks of it, that the objectives are fully multi coated.
The bino has one adapter socket.
The bino is in good condition. Optics are clean, though the eyepiece coatings have some light worn out marks. Well collimated.
Eye relief is very good. Apparent field is very nice, about 60 degrees, so it gives a big picture.
The only reason I'm selling is cos I need to pay for other astro purchases.
PM me if you're interested.
Thanks!
