Spyglasses

Tasco delivers fully-coated optics with high-end quality which ensures clear images. Added comfort, by the fold-down cups and the rubber armor, protects your binoculars from accidents or scratches. However, these set of binoculars aren’t manufactured for close distance views and they don’t provide a central focus wheel for adjustments. So if you want to simply magnify views these are a great option.

One thing I have learned after researching is that the best binoculars for astronomy depend on your preference. 7 by 35 binoculars You might want to ask yourself the question, what are a good pair of binoculars? Our here will help you.

It seems that some of them came with a ‘hindsight’ feature. Napoleon’s in his St Helena ramblings seems to have seen Prussians through several woods and high ground. Wellington’s also seemed to possess similar exceptional qualities, seeing the progress of Ligny from Quatre Bras! The saying is ‘seeing is believing’ but more accurately ‘believing is seeing’

Thanks Tom.

The article does not answer the basic question, but it does show that some of the basic issues with image clarity were solved by our period of study. So a typical spyglass might be as good as what Wellington used at Waterloo.

Thank you for that link Garry.

I suspect that Wellington's spyglass was probably better than average. Nonetheless, the information is quite useful.

Best regards, Terry

I have a note that Wellington's telescope was 30x magnification at Waterloo and that this is pretty standard for the time. https://ageofrevolution.org/200-object/wellingtons-telescope/
