Buying Big Binoculars

100mm (4inch) Binoculars, suitable for Astronomy
are available in Australia for under $500!

These are not APO (Apochromat), imperfect edge sharpness and poor color correction is common to all brands, yet the optics are good for the price.
A pair of Semi-APO Binoculars of this size would cost you well over $3000.
These are all manufactured in China, and are usually re-badged by the supplier.

Common features (may vary):
1. The eyepieces focus individually.
2. Fully multi-coated optics.
3. BAK-4 Porro prisms.
4. 2.5° field of view (at 25x).
5. 4mm exit pupil.
6. Eye relief distance of 18mm (OK for eyeglass wearers).
7. Sliding 1/4" mount for coupling to a tripod.
8. Weight: 3.5 to 4.5 Kg (8 - 10.0 lbs).
9. Tripod Required.
