# Determine how much of the sky can be imaged in a single night

• willmc
In summary, the question is regarding the amount of sky that can be imaged in a single night by a telescope with a field of view of 2100 x 1700 arc seconds and a read out time of 5 seconds per exposure. The amount of celestial sphere visible for the specific location is 26360.64 degree squared for 12 hours. The individual is seeking assistance in calculating the amount of sky that can be imaged in 12 hours.

Hello,
I am doing an assignment, and am required to work out how much of the sky can be imaged in a single night by a telescope.

If the amount of celestial sphere that is visible for this particular site is 26360.64 degree squared for the 12 hours.

The field of view of the telescope is 2100 x 1700 arc seconds, with a read out time of 5 seconds per exposure.

How would i figure out how much sky can be imaged over 12 hours?

I really need help.. this is due tonight :/
Regards
William

Welcome to PF;
That's a cool question - please show us your attempt at it.

## 1. How is the amount of sky that can be imaged determined?

The amount of sky that can be imaged in a single night is determined by various factors such as the field of view of the telescope, the size of the camera sensor, and the length of the exposure time. These factors help determine the total area of the sky that can be captured in a single image.

## 2. Is the entire sky visible in a single night?

No, the entire sky is not visible in a single night. The Earth's rotation limits the amount of sky that can be seen in one night. Additionally, factors such as weather conditions and the location of the observer can also affect the visibility of certain parts of the sky.

## 3. Can the amount of sky imaged in a single night vary?

Yes, the amount of sky that can be imaged in a single night can vary depending on the factors mentioned earlier. For example, if the telescope has a larger field of view or a longer exposure time, it can capture a larger area of the sky compared to a smaller telescope with a shorter exposure time.

## 4. How does light pollution affect the amount of sky that can be imaged in a single night?

Light pollution can greatly affect the amount of sky that can be imaged in a single night. Bright city lights and other sources of light pollution can make it difficult to capture faint objects in the sky, limiting the amount of sky that can be imaged. Observing from a darker location can increase the amount of sky that can be captured in a single night.

## 5. Can advanced technology improve the amount of sky that can be imaged in a single night?

Yes, advancements in technology such as larger telescopes, more sensitive cameras, and better image processing techniques have greatly improved the amount of sky that can be imaged in a single night. These advancements have allowed scientists to capture more detailed and deeper images of the sky, increasing the amount of information that can be obtained in a single night of observation.
