Well, darling, to capture a time-lapse video of the night sky with the North Star as your focal point, you should set up your camera on a sturdy tripod, aim at the North Star, use a wide-angle lens, and set your camera to a long exposure to capture the movement of the stars. Make sure your focus is spot on and patiently let your camera do its magic as the Earth twirls away. You'll have a stellar time-lapse in no time!

A telescope consists of two lenses. 1) The main lens which collects the light ( it is relatively bigger that eyepiece). 2) Eye piece , through which we see. Magnification of a telescope depends on the focal length of the eye piece and the main lens. Magnification = Focal length of the main lens / Focal length of the eyepiece . For example : If the focal length of the main lens is 12 units and the focal length of the eyepiece is 2 units , then the magnification will be 12/2 = 6.When the focal length of the main lens is constant , the focal length of the eyepiece is inversely proportional to the magnification.
If you shine a parallel (ie unfocussed) beam of light perpendicular to a convex lens it will focus to a point on the other side. That place is called the focal point of the lens. Its distance to the lens is called the focal length.
Focus or the focal point.
The 85mm crop sensor equivalent focal length for capturing portraits with a camera is around 127.5mm.
The shortest focal length lens available for capturing wide-angle shots is typically around 10-14mm.
The focal length of a telephoto lens is longer than the focal length of a wide-angle lens. Telephoto lenses have a narrow field of view and are ideal for capturing distant subjects, while wide-angle lenses have a wider field of view and are great for capturing expansive scenes.
The ideal focal length for capturing detailed shots of the moon in photography is typically around 200-300mm. This allows for close-up shots that reveal the moon's surface details.
The phone camera focal length is important for capturing high-quality images because it determines the field of view and perspective of the photo. A longer focal length can result in better image quality by reducing distortion and improving sharpness, especially for distant subjects.
The ideal objective focal length for capturing detailed images of distant subjects in wildlife photography is typically between 300mm and 600mm. These longer focal lengths allow you to get close-up shots of animals without disturbing them, resulting in sharp and detailed images.
Using a camera lens with a 200mm focal length for capturing distant subjects offers advantages such as magnifying the subject, creating a shallow depth of field for a blurred background, and reducing distortion in the image.
It depends on the specific needs of the photographer. A greater focal length is better for capturing distant subjects and achieving a shallower depth of field, while a smaller focal length is better for capturing wider scenes and fitting more into the frame. Each has its own advantages depending on the desired outcome of the photograph.
In photography, the field of view is affected by the focal length of the lens. A shorter focal length results in a wider field of view, capturing more in the frame, while a longer focal length narrows the field of view, zooming in on a specific area.
Using a camera lens with a low focal length for wide-angle shots offers advantages such as capturing more of the scene in a single frame, creating a sense of depth and perspective, and minimizing distortion at the edges of the image.
A telephoto lens is the best option for capturing far away shots due to its long focal length, which allows you to zoom in on distant subjects with clarity and detail.
