While many enjoy the view of the ocean from a distance, others may want to see things closer and in more detail, and a telescope helps with this. Sailors and those operating around the ocean found these tools indispensible. Because the water was so vast, these items would be used to zoom in on things such as adverse weather conditions. The concave lenses of mirror-treated glass allowed for the first telescope to be made. Though this technology was known about before, no one had ever thought to put it in a portable tube. When placed in this sort of cylinder, the lenses allow the human eye’s vision to be magnified tenfold. Hawks and other birds have this zoomed-in sort of vision.

In order to avoid hazards, a spyglass telescope was used to survey the sea with great accuracy and plot a course for the ship. Prior to the invention of the spyglass telescope, ships had a designated look out who had excellent vision. With the spyglass telescope, far away dangers could be seen much earlier, and with much more certainty. Because of their varied and vital uses, the spyglass telescope quickly rocketed up to reach a top spot in a sailor’s toolbox. Dock workers, lighthouse keepers, and those who ferried people across smaller bodies of water all came to rely on this item heavily. The spread of the spyglass telescope has only increased over time, and it is very possible to find one of these items almost anywhere in the world. For those who love travel and excitement, the spyglass is a must-have tool.

One of the first spyglass telescopes was made using a sturdy type of wood. As a prototype, the wood allowed the lenses to be taken out and realigned as adjustments were made in the pursuit of perfection. Because wood was prone to expanding when near water, many telescopes began to be made in cast metal. Tin was the first metal used to craft these telescopes. In trial runs, the tin rusted in no time at all. The salt corrosion of the ocean seemed to be resisted by the bronze metal better, and many telescopes were soon made using this material. When these items were made from brass, the metal defied all expectations. All types of rust and wear of the ocean were resisted by brass metal without fail.

One of the most popular materials these telescopes are crafted from today is stainless steel. In order to compensate for where they are most often used, these spyglasses are made to be water tight and waterproof. Extremely fancy spyglasses may have jewels or colored glass inset into them, while others may have names or dates engraved into their casing. Many people prefer those spyglasses that are jointed into segments and can be collapsed to a smaller state for easy carrying. Because the segments hinder decoration, these types are prone to be a little drabber than the straight type. Many of these items are understated and full of a rich maritime history, and can be implemented in most any room as a decorative installment.
