Limiting magnitude can be calculated by using a telescope.

The limiting magnitude at Bryce Point that night was 7.3.

In some cases, limiting magnitude refers to the utter threshold of detection.

For those who lives in the immediate suburbs of New York City, the limiting magnitude might be 4.0.

A star close to the limiting magnitude (22) of the Schmidt plate lies roughly 0.7arcsec to the west of the radio position.

Limiting magnitude is traditionally estimated by searching for faint stars of known magnitude.

This represents the limiting magnitude correction factor.

I have drawn this chart to a larger scale because it provides an excellent check of the limiting magnitude of binoculars.

This is easily accomplished by cutting off the data at the edge of where the lowest absolute magnitude objects would be hitting the limiting magnitude.

It merged two components: first, a survey of around 58,000 objects as complete as possible to the following limiting magnitudes:

With this technique, observers are reporting a naked eye limiting magnitude (NELM) between 1 and 7.

The limiting magnitude of the survey varied depending on the region of the sky, but is commonly quoted as 22nd magnitude on average.

This selection had to balance 'a priori' scientific interest, and the observing programme's limiting magnitude, total observing time, and sky uniformity constraints.

The CCD can collect light for as long as the image is crossing it, allowing a dimmer limiting magnitude to be reached.

In astronomy, limiting magnitude is the faintest apparent magnitude of a celestial body that is detectable or detected by a given instrument.

You can choose a region of the sky, set the limiting magnitude and set a time sequence (time step, number of steps, and step interval).

In 2005, the VLTI was routinely producing observations, although with a brighter limiting magnitude and poorer observing efficiency than expected.

Mr. Moore's description of it as the darkest he had ever seen was not mere guesswork; he determines darkness through a measure called the "limiting magnitude."

The original goal of 11 mag for the limiting magnitude was generally surpassed, however, with some observatories routinely measuring stars as faint as 13 mag.

In amateur astronomy, limiting magnitude frequently refers to the faintest stars that can be seen with the unaided eye near the zenith on clear moonless nights.

In 2013 an app was developed based on Google's Sky Map that allows non-specialists to estimate the limiting magnitude in polluted areas using their phone.

Down to a limiting magnitude of +5, it is superseded in redness only by the Garnet Star (Mu Cephei).

The Bortle scale is a nine-level numeric scale that measures the night sky's and stars' brightness (naked-eye and stellar limiting magnitude) of a particular location.

Many basic observing references quote a limiting magnitude of 6, as this is the approximate limit of star maps which date from before the invention of the telescope.

It was discovered by J.R. Hind in 1855 who initially thought it was a nova; it quickly faded below his telescope's limiting magnitude.
