Eyepieces are an important thing. Though a telescope’s objective is responsible for forming the image, the image cannot be inspected without an eyepiece. Fortunately, due to their relatively small size, eyepieces of sufficient quality are generally much cheaper than suitable telescopes. But that d...

In this article, we will discuss the advantages and disadvantages of monoculars compared to binoculars and telescopes, their ideal use cases, the similarities and differences in magnification and field of view, the history of monoculars, and the types of lenses and prisms used in their constructio...
etc. The "50" means 50mm (~2 inch) objectives (aperture). This gives light gathering ability similar to many small telescopes. Many advanced star gazers regularly use binoculars to either locate items to focus telescopes on, or just for the wider field of view. ...

I always wore glasses & before telescopes, binoculars always needed long eye relief. Swift Osprey (7×42) were the answer. With telescopes it was Erfles & Barlows, cameras had to have large or diopter-friendly viewfinders. A love-hate 13mm T1 Nagler was addictive for its 82° AFOV, &...
