It's by far the most popular thing I've written, and gets quite a lot of links from various SGL threads. It originally was just a simple calculator, but was expanded to something of a fov simulator. I've been working on a new version on-and-off for some time now, and it's finally at a stage where it does something useful so would love to get some feedback.

There are a lot of terminologies to learn when you start a new hobby and astronomy is no exception. So what is it? Put very simply, the field of view is how much sky you can see, as measured in degrees. Since we only have eyes at the front that look forward, this is impossible. More realistically then, the average human eye, without the help of binoculars or a telescope, has a field of view of about degrees. In other words, we can typically see everything in front of us and a little way to the sides. In astronomy, the field of view usually refers to how much of the sky we can see through either binoculars or the eyepiece of a telescope. You can observe the Moon with two different sets of binoculars that both have a magnification of 10x. If one has a larger field of view than the other, it simply means you can see more of the surrounding sky. The Moon itself will appear exactly the same through both pairs of binoculars.

The final reason is largely aesthetic. I like it, too, but I have a question.

The field of view FOV in a telescope defines the extent of the observable universe that is visible through the eyepiece at any given moment. Knowing the FOV allows astronomers to determine the ideal eyepiece for a specific observation. Calculation of the TFOV is done by dividing the AFOV of the eyepiece by the magnification of the telescope, or through the relationship of the focal lengths of the telescope and the eyepiece. The TFOV is typically expressed in degrees. The FOV in the eyepiece is determined by its specific AFOV, and the choice of eyepiece thereby plays a vital role in the observational experience. The relationship between FOV and magnification is inversely proportional, such that an increase in magnification results in a narrower field of view, while a decrease in magnification yields a broader view. The field of view FOV in a telescope refers to the extent of the observable sky that can be viewed at a single point in time. The FOV plays a pivotal role in observational astronomy as it dictates the range of celestial objects that can be observed. For instance, a telescope with a larger FOV enables the viewing of expansive celestial bodies like nebulae and galaxies, whereas a telescope with a smaller FOV is more suitable for observing smaller entities like planets and stars.

Telescopes open our eyes to the marvel of the cosmos: the telescope field of view calculator will tell you exactly how much! Our eyes work pretty okay, but they are absolutely useless when it comes to distant things. It makes sense: we evolved to see predators a hundred meters away, not stars on the other side of the galaxy. That's where telescopes really give us an edge. A telescope is an optical device that collects light , thanks to a well-thought set of lenses, which focuses and magnifies an image on our retina. The difference lies in how they focus the light. Refractors use a lens called an objective lens, while reflectors use a mirror placed at the bottom of the telescope in this case, the collecting end is called the aperture.

I genuinely believe that. In fact I often offer it as an explanation when asked how I learned the ropes. One other thing - could you do a selectable angle to rotate to, or add a 45 degree option? Dividing 40 by 81 gives me 0. We forgot the 'Add New Equipment to Database' button. I think the others do, too. That looks very nice David. If you stand just inches away from a tree, you might only see the bark and a few leaves. A simulated view of the full Moon through an 8mm eyepiece at 81x with a field of view of 0.

I'm sure it's probably still a work in progress, but just to let you know that the QHYCCD cameras are missing from the drop down sub-menu. Already replaced your previous version on my bookmarks bar love the new simbad and bino options. My preference for short explanations has resulted in an ambiguous sentence. It was fact when I saw your calculator and various others that inspired me. Heading over to take a look. As a general rule, the lower the magnification the larger the field of view and the higher the magnification, the smaller the field of view.
