Youre not planning to be out all night, and you are not doing photography.There are several reasons why this is necessary, depending on what you are planning to do next.
Telescope Polar Alignment Website Manual Equatorial MountWhile this is not, in fact, how you are likely to find objects with an inexpensive manual equatorial mount with manual setting circles, it is essential for computerized go-to equatorial mounts, which depend on this system.
It just means pointing the polar axis of your mount precisely toward the North Celestial Pole. There may be a hole through the mount along this axis, or it may just be solid metal. The polar axis is the line through the mount that does not move when you move the telescope in either direction. For coarse left-right pointing you can just lift the tripods legs off the ground and turn the entire mount and tripod, and you can do coarse up-down adjustment by adjusting the length of the tripod legs. These are separate from the controls that move the telescope on the mount. Polar alignment is done by moving the polar axis or by moving the mount itself, not by moving the telescope on the mount. The slow-motion controls you use to point the telescope are not used for polar alignment. Dont attach the telescope leave it in the house, in a locked room. If possible, release a vicious animal such as a mongoose in the room with the telescope. A Honey Badger also works well, but it can be difficult to persuade them to leave afterward.) This is so you are not tempted to think that you polar align by worrying about where the telescope is pointing. Telescope Polar Alignment Website Free The MongooseAfter the mount is polar aligned, go into the house, free the mongoose, and get the telescope and attach it to the mount. It is the point in the sky that does not move through the night or through the year all the stars in the sky appear to rotate around this point. The NCP is very close to the star Polaris, otherwise known as the North Star. For many polar alignment purposes, you can consider the NCP to be exactly equal to Polaris. Astronomers in the Southern hemisphere dont have the convenience of a star located at the South Celestial Pole, and must use other nearby objects to estimate its position. Sorry, Southern neighbours, I have no experience to help you with that, but I hope the rest of this article is still useful. The Polar Alignment Scope method mentioned below, with a polar alignment scope marked for the Southern hemisphere, is your best bet. That raises the question, how accurate does polar alignment have to be. Some go-to systems (like older Celestron and Meade systems) require moderately good polar alignment for the go-to to work accurately. Others, such as the Gemini system on Losmandy mounts, can compensate for inaccurate polar alignment. Serious astrophotographers planning to take long exposures might spend more than an hour on polar alignment before they begin their work. ![]() You will set up your telescope and spend one to three hours observing a variety of objects, then put it away.
