My own personal experience is that they are no more difficult to manage than a standard alt-azimuth and have the advantage that when polar aligned they make life easier when your observing as you have only one control to handle to keep the telescope pointed at an object. It has to be in polar alignment with the axis of the earth. For more precise alignment, such as when using a computerized telescope, there are a few extra steps. Found inside – Page 39A polar alignment your favorite section of the sky ! ... A mount has now become the norm for properly aligned equatorial mount with clock professional observatories as well ... and drive will greatly add to your viewing pleasure ... Dual saddle plate accommodates any dovetail - D or V series. equatorial mount. For a detailed overview, check out this guide on mastering your polar alignment to learn more. Ability to use polar alignment devices for a more accurate polar alignment and longer exposures without star trails. Setup your mount so that the tube is oriented like the image here. What we've found, however, is a short supply of instructions for astronomers in the Southern Hemisphere - what do you do if you want to polar . For visual use, a rough polar alignment works fine. If you found this site/page helpful why not buy us a coffee to say thank you and say hi. Traditionally the equatorial mount is quite heavy, but recent ones are compact and . Set up the equatorial mount with the north leg and counterweight pointing in the approximate direction of north. If astrophotography is in your plans, an optional polar finder #3912 is available to increase the accuracy of your alignment. Review of the Hotech Self Centering Laser Collimator, Review of the Celestron 4SE GoTo Maksutov, Review of the Sky-Watcher 130PM & Celestron Eye-Opener Kit, Review of the Skywatcher Skymax 180 Pro Maksutov, Review of the TAL 100RS 4″ Achromatic Refractor. Its not a perfect alignment but it will be perfectly adequate for most observing needs with an equatorial mount. That level of accuracy is easy to achieve with . This method is recognized for returning very accurate results and relies on your auto-guider to measure polar alignment error. These star trackers help telescopes to track the heavenly bodies in the night sky. Found insideHere's how to manually achieve polar alignment the old-fashioned way. Using an equatorial mounted telescope, level the mount, then aim the tube straight back along the right ascension axis toward Polaris in the northern hemisphere,6 or ... Polar Alignment (with Polaris) for Equatorial Telescopes The purpose of Polar Alignment is to point the Right Ascension axis (Polar Axis) of the telescope's equatorial mount to a Celestial Pole, enabling it to compensate for the rotation of the Earth and follow a fixed celestial object without adjusting the Declination. However, when it comes to deep-sky imaging the targets are less tolerant, but our method benefits from allowing you to autoguide to an extent. [Enlargement] The imaginary field of view of the polar alignment scope on the app is enlarged and you can easily check the position of the stars. A polar scope makes aligning the polar axis of this mount with the North celestial pole much easier. For basic visual observing, polar alignment is not particularly critical and is easy to do. This little scope usually sits directly inside the mount, and has a reticle in which you can center Polaris. Also, you need to make use of heavy counterweights to keep the telescopes of in place. That’s the beauty of autoguiding: if the stars do drift slowly across the field of view, automatic adjustments by the autoguider compensate for this drift. If the mount has setting circles. Found inside – Page 356Like any equatorial mount, an EQ platform must be polar aligned if it is to track stellar motion properly. For visual use, a rough polar alignment works fine. You simply place the EQ platform with the north-south central axis pointing ... There are several reasons why this is necessary, depending on what you are planning to do next: . At my college's observatory, I have been using a pier-mounted CGE Pro and an older Celestron CGE on wheels, rolling it out of the building onto a concrete pad to do visual observing while . Polar aligning an equatorial mount for astrophotography purposes is not as easy as just pointing the mount to Polaris and commencing an imaging session. your scope is mounted on an equatorial wedge or on a German Equatorial Mount (GEM), it is still important that the alignment of the scope be as close to perfect as possible. How to Polar Align an Equatorial Mount in the Southern Hemisphere. Found inside – Page 20For those wanting to explore the Moon for several tens of minutes or to take some good - quality photos an equatorial mount with a polar alignment scope is called for . The ideal set - up is to have a permanent stand carefully aligned ... Alignment with the SCP. 3. The dark field illuminated dial makes the polar alignment simple and easy and it can be done just in minutes. Add to cart. More on this later. If required, revisit Steps 4 and 5 until any image drift stops. You will need to take these precautions due to the Sun’s excessive heat and light. Getting your Equatorial Mount aligned is the most important step before you start capturing light from space. The polar axis of an equatorial mount should point at the north celestial pole and the process of making this so is called "polar aligning". Polar Alignment Last Revision: 8/19/2006 Page 1 of 5 Polar Alignment Even the most casual observer knows that the Sun and stars move across the sky. As one becomes more experienced with practice, the polar alignment process will become second nature and will take only a fraction of the time as it did the first time. If it drifts north or south in the field of view, the polar alignment is slightly out. Found inside – Page 142Once aligned, the telescope can be steered to follow a star simply by turning the polarpointing axis as Earth rotates. The type of equatorial mount most often encountered with small refracting telescopes is known as the German mounting. The Celestron CI-700, while no longer sold, was a private label equivalent to the G-11, and it was apparently made by Losmandy. The mount should now, to all intents and purposes, be polar aligned. We’ll go over the basic types of polar aligning your equatorial mount here and give you some pros and cons for each type. Shown above is a simple equatorial mount. Polar Alignment Last Revision: 8/19/2006 Page 1 of 5 Polar Alignment Even the most casual observer knows that the Sun and stars move across the sky. Setting Up your Mount. If you're using a German equatorial mount with your lens or telescope, attach your optic to the mount, set the declination to +90°, and keep the lens cap on. Some users report the scales being off by as much as 10′ on the scale. OPT experts walk you through the essential step to capture stunning . What have you experienced to be the easiest to work with? It's true that the more accurately an equatorial mount is aligned with Earth's polar axis, the more faithfully the telescope will track the sky. Found inside – Page viiIf you have an equatorial mount, you'll still need to roughly polar align, but this really takes only a few moments. ... This would include very accurate polar alignment (for equatorial mounts), then finding a guide star using his ...
