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.

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 did not ever realise how much pixel size and "seeing" were related.

That looks very nice David. We have also included this advice on the calculator page: Pixel-scale the subject of this fov calculator telescope is arguably the most important factor to consider when choosing a camera for your telescope, but there are others: Sensitivity, dark current, read noise, anti blooming, etc. Thanks so much for sharing your hard work.

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.

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.

Without his enthusiasm, patience and wizardry Astronomy Tools would not exist. Thank you Dave, I just want you to know that on a personal level I really appreciate the work you've put into this. Grant Posted July 14, A Celestron 20mm eyepiece that typically comes as standard with their telescopes. Pixel-scale the subject of this calculator is arguably the most important factor to consider when choosing a camera for your telescope, but there are others: Sensitivity, dark current, read noise, anti blooming, etc. So the larger your field of view, the more stars are visible to use as reference points. A simulated view of the full Moon through an 8mm eyepiece at 81x with a field of view of 0. Scott Posted August 11, Forgot your password?

It's back! Of course, if you want to see anything through a telescope, you have to look through an eyepiece, but in order to for the light to reach your eye, it first has to enter the telescope through the other end. David, You have my eternal gratitude for taking the time to write this incredibly useful resource and the generosity to make it available to everyone. FLO Posted December 3, The true field of view is the number of degrees your eyepiece shows you when you use it with your telescope. Tom was about six months ahead of me and taught me a huge amount, as did many others. Prev 1 2 Next Page 1 of 2. It isn't a 'how to choose' article but we have included this advice on the calculator page:. Sign In Sign Up. Here is a link to the original thread. Many binoculars are marked with a second set of numbers, close to one of the eyepieces and often below the magnification and objective lens size.
