Is it necessary to align polar alignment on go-to scopes?
- Depending on the sort of photography being done via the telescope, highly precise polar alignment is required for successful photography. Before beginning their work, serious astrophotographers who aim to use long exposures may spend more than an hour aligning their cameras. Polar alignment might take many days for permanent observatory sites.

Why do you need to polar align a telescope?
An important first step in preparing for a night of visual observation or astrophotography is to align the stars on the horizon. What is the significance of this? It is possible to follow objects in space with pinpoint accuracy by adjusting the axis of your telescope mount to line it with the motion of the sky. For owners of German equatorial mounts (GEMs), the procedure is rather straightforward.
How do you polar align a telescope during the day?
One effective method is to make advantage of the Sun. Using a bubble level, carefully level the mount and align the polar axis to the latitude of your location on the planet. Using a weighted string, suspend a protractor from the mount (in between the tripod legs) and place it on the ground so that it is centered beneath the string.
How do you get perfect polar alignment?
How to Accurately Complete the Polar Alignment Procedure
- To begin, point the mount’s polar axis in the general direction of Polaris. If the star appears to be drifting southward in the eyepiece, this indicates that the polar axis is oriented too far east.
- If the star is drifting north, this indicates that the polar axis is too far west. The polar axis should be rotated left or right as needed until there is no more drift.
How accurate is polar alignment?
All of this is sound advice. In any event, there is no such thing as a “perfect” polar alignment, at least not when it comes to tracking precision on a real-world object. Due to refraction in the atmosphere, the apparent rate of motion of any target will change depending on its height, which is the origin of this phenomenon.
What does an equatorial mount do?
An equatorial mount is a type of instrument mount that adjusts for the rotation of the Earth by having one rotating axis that is parallel to the axis of rotation of the Earth. This sort of mount is used to hold astronomical telescopes and digital cameras in their proper positions.
How do you polar align a wedge?
To align your hand control, press the Align button and follow the on-screen directions.
- Once you have clicked the align button, pick Polar Align from the drop-down menu. Select Align mount from the Polar align drop-down menu. It will prompt you to center the star in your eyepiece when your mount has slewn to a particular star.
What is good polar alignment?
A polar alignment that is within one arc minute of the pole is generally regarded satisfactory and sufficient for long exposure photography.
How do you illuminate a polar scope?
Cover (or paint) the bulb with some red cellophane to give it a festive look. The flashlight should be taped to the mount, and the light should be directed obliquely into the north side of the PA scope hole, such that it lights the reticle but does not obscure Polaris.
