Steps to making a spyglass in Minecraft.
Total Time: 2 minutes
Make copper ingots.
You can make them by baking copper ore.

You can get them by mining amethyst crystals.
Go to a crafting table and arrange the items you’ve obtained as follows : 1 amethyst shard on top, 2 copper ingots underneath.
This will give you your spyglass.
Using the spyglass
The spyglass is used to zoom in on a specific location in the player’s field of view (FOV). The spyglass changes the FOV to 1⁄10 of the FOV set in the options. By default, the FOV is set to 70, giving a field of view of 7 through the spyglass.
The FOV can be set from 30 to 110, giving a FOV of 3 to 11 through the spyglass. A circular vignette is applied during use, similar to the effect produced by wearing a carved pumpkin. Pressing F1 removes the vignette, similar to a carved pumpkin. The player is slowed down as he looks through the spyglass.
