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.

Forgot your password? It's back! Our aim was to make it easy for someone to determine if a CCD camera and telescope are a good match. We included a link to the experimental calculator and invited comment. Thank-you to everyone who responded with suggestions. This finished calculator includes many of the improvements you suggested, we hope you find it useful. CCD Suitability Calculator. Without his enthusiasm, patience and wizardry Astronomy Tools would not exist. We forgot the 'Add New Equipment to Database' button. Reducers and barlows need to be added by us. Most are already listed but we have received a request for the the Takahashi 0. If there are others you would like included please ask. Great tool and very useful.

I liked the Mk1 and I love the Fov calculator telescope. Recommended Posts. Oh, one thing, I'm planning a website dedicate to the Messier catalogue, it'll be nice if we could embed the FOV calculator as well - all credit will be give of course.

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.

Heading over to take a look. FLO Posted December 3, My shortest eyepiece has a focal length of 3 mm, which gives me a magnification of nearly x. In our tandem Tak we have two identical chips sizes next to each other full format Kodaks but one has 9 micron pixels and the other a larger number of 7. It isn't a 'how to choose' article. Yes, I see your point. Updated: Jan 24, Great calculator - only thing I would find useful is some way even as a text list is to be able to save the data fields which would make it easier to transfer to other SW requiring these details? I don't understand this: but using more pixels than is necessary restricts the amount of sky you can fit onto the camera sensor. Field of view calculator v2. Unlike a telescope, the focal lengths of eyepieces are very short and will typically range anywhere between 3mm and about 40mm. In other words, light travels mm 65cm from the aperture to the eyepiece.

Our Astronomy Experts. You are right, this is a wonderful time for anyone interested in astronomy. There are a lot of terminologies to learn when you start a new hobby and astronomy is no exception. There are two other reasons why your field of view is important — and they both come into play once you have your target in your sights. Garethr Posted December 2, Sign in with Facebook. By using this site, you agree to our Terms of Use. So what is it? Tim Posted December 3, I think it's made of tiny incremental improvements. 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. I'd just like to add my name to the list of those who are grateful for this excellent resource.
