Calculating The True Field Of View Of A Telescope Eyepiece

Telescope

One of the things that originally puzzled me when I first bought my telescope was the business of apparent field of view and true (or actual) field of view. When you look through your telescope, the area of the sky you can see is known as the true (or actual) field of view. The field […]

Choosing Your Telescope Eyepieces

Lens

When beginning astronomers start looking at telescopes, one of the least understood aspects of these optical instruments are simple telescope eyepieces. While lenses and mirrors and designs are easy to grasp, the actual eyepiece itself can be somewhat confusing. However, they are vital parts of the telescope, as they provide the final creation and magnification […]

Understanding Astronomy Eyepieces

Solar Shadow

The purpose of an eyepiece is to magnify the focused image, and different eyepieces can be used to give different magnifications and fields of view. You will need to experiment with different ones to find the best one for a particular application. For example, if you want to observe a large area of sky, you […]

Planet Observing
