I found some inexpensive Humvee 20x50 binoculars on sale for $20 (regular $40 or so). I couldn't believe it when I was testing them out. I thought I was doing something wrongly.
What couldn't you believe?
20x50 binoculars are difficult and expensive to engineer for satisfactory performance and a Tripod will still be required for even the high end 20x50s and will still even need to be used in good lighting conditions. Cheap 20x50s, well I suspect you will see a lot lot more using
these. (sorry for the recommendation). The field of view will be very restricted, low light dusk and dawn conditions will be effectively useless and focusing quite difficult let alone distortion, aberration, focal range and colour definition by comparison.
