First of all, it is important to know that we are not talking about your camera when we refer to focal length. The camera of course plays an important role, but it is the job of thelensto take the light and focus it at a particular point. The light from the scene hits the object ...
Focal length is an essential element in photography as this describes the angle of view or how much of a scene you can capture through the lens. Focal length also enables you to magnify subjects or make subjects appear larger within the frame. The focal length is one of the first things y...

and speciality lenses can extend outside this range as well. A 10mm focal length would be a very wide lens (capturing a lot of the scene), and 500mm would be a very narrow lens (capturing only a small part of the scene – giving a large magnification like binoculars or a telescope)....

Image scale comes into play when you want to maximize the effectiveness of a particular camera/telescope system in your unique imaging (sky) conditions. This number is measured in arcseconds per pixel, using the following equation:pixel size / focal length x 206. ...
Laser Collimator In A Telescope Laser Collimation In Labs A laser collimator is a device that is used to narrow a beam of light. It can be used to arrange the beam of light in a particular direction, or to reduce the spatial cross-section of a beam to make it smaller. A laser collima...
