This essential piece of gear astrophotographers use is called an equatorial mount, or perhaps more commonly known, a star tracker. These devices were invented to allow telescopes to automatically track objects in the night sky without having to manually move the telescope to keep the objects in the eyepiece.
Hereof, How do I choose a star tracker?
How long does it take to get exposed to star tracker? If you have everything tightened up and aligned properly then, in my experience, a 50mm lens can comfortably take 120-second exposures; a 135mm lens 60-second exposures; a 300mm lens 30-second exposures, and wide-angle lenses up to two or even 2.5-minute long exposures before some trailing is evident.
Accordingly, What does an equatorial mount do? An equatorial mount is a mount for instruments that compensates for Earth’s rotation by having one rotational axis, the polar axis, parallel to the Earth’s axis of rotation. This type of mount is used for astronomical telescopes and cameras.
Do you need a SkyTracker for astrophotography?
Astrophotography demands long-exposure tracked images to collect as much signal (light) as possible, and that is exactly what a star tracker allows you to do. I recommend the Sky-Watcher Star Adventurer 2i (Pro Pack) for beginner astrophotographers looking for the best overall experience.
Can you track the moon with a star tracker? The Star Adventurer Mount from Sky-Watcher USA is an ideal tool for taking photos of the moon because it tracks celestial bodies. Keep the moon (or the sun or stars) in full view by using the mount to track it across the sky.
What does a star tracker do? A star tracker is a motorised, equatorial mount that fits on top of a tripod and allows a camera to follow the stars (or a planet, a comet, or anything else) as they are carried across the sky by the rotation of Earth.
What is the 500 rule in astrophotography? The 500 rule is used to measure the maximum exposure time you can shoot before the stars become blurry or before star trails appear. Setting the shutter speed for longer than allowed by this rule will result in images that do not have sharp stars.
What is the 500 or 300 rule in photography?
Rule of 500 (or 300)
When taking an untracked photo of the night sky using a camera on a tripod, this rule tells you how long you can expose before the stars begin to trail. You take the number 500 and divide by the focal length of your lens. For example, if you have a 20-mm wide angle lens, then 500 / 20 = 25.
How do you photograph stars without trails? Star Photography – Setting Up the Shot
- Choose a location for the photo shoot that’s away from light pollution. …
- Mount your camera to a solid tripod. …
- Remove your camera strap from your camera. …
- Select exposure settings to maximize the quality of the shot. …
- Set your lens to manual focus and focus it at infinity.
What is a Dobsonian mount?
A Dobsonian telescope is an altazimuth-mounted Newtonian telescope design popularized by John Dobson in 1965 and credited with vastly increasing the size of telescopes available to amateur astronomers.
What is eq1 mount? The Orion EQ-1 equatorial mount and tripod provides solid support and control for small astronomical telescopes. Capable of managing telescopes and equipment combinations weighing up to 7 lbs.
What is a telescope wedge?
This limits the potential exposure time when using the telescope for astrophotography. The Wedge tilts the telescope’s azimuth axis so that it tracks stars as they move in an arc around the celestial pole. This keeps objects centered without rotation, allowing you to take longer exposure astrophotos.

How do you photograph Milky Way with star tracker?
Can you use a gimbal for astrophotography? In other terms: yes, any gimbal could be used as a star tracker, even if they don’t use step motors.
How do you photograph the moon with a star tracker?
What is needed for astrophotography? There are really just a few requirements when it comes to the gear that you will need for great astrophotography. A camera that handles high ISOs well, wide angle prime lenses that have an aperture of at least f2. 8, a tripod, and a light pollution filter if you can’t get far enough away from city lights.
What is a tracked photo?
Image tracking detect two-dimensional planar images from a custom-defined target set, and then continuously tracks the images’ locations and orientations as you or they move in the setting. With image tracking, you can place authored content based on the presence of a physical image.
How accurate is star tracker? Statistical analysis shows that the pointing and rolling accuracy of the star tracker within the measurement time in the entire field of view is 3.30″ (3σ) and 23.96″ (3σ), respectively. The measurement results meet the accuracy requirements of the system specifications.
