However, to understand your telescope more thoroughly , you need to know a little about the night sky. The NexStar automatically selects the best slewing rate for aligning objects in both the Star Pointer and the eyepiece. Doing an Undo Sync will restore the pointing of your telescope to its original alignment. If you are new to astronomy, you may wish to start off by using the NexStar's built-in Sky Tour feature, which commands the NexStar to find the most interesting objects in the sky and automaticall slews to each one. For astronomical observing, this allows you to observe in positions that are more comfortable than if you were to look straight thr Summary of the content on the page No. Use the included NexStar+ hand control to locate over 40,000 celestial objects, or take a Sky Tour and let your telescope show you the best objects currently visible. They are the high-end in the telescope world.
Use the direction arrow buttons to slew Summary of the content on the page No. If the finderscope has been properly aligned with the telescope tube, the alignment star should now be visible inside the field of view of the eyepiece. Telescope Compatibility Focus Motor Compatibility Aperture Celestron Telescope Design Models Compatible with 94155 Focus Motor? The nature of the optical design determines how the light is focused. Align: Instructs the NexStar to use a selected star or object as an alignment position. Keep in mind that the card should be held a few inches in front of the telescope, and not touching it. It is best to carry the telescope by holding it from the lower portion of the fork arm and from the bottom of the base. Additionally, I'm very happy with the portability of this telescope, especially considering the high focal length compared to its size.
The telescope can be controlled at nine different speed rates. Remove all of the accessories from their individual boxes. Internal heat build-up inside the telescope can cause these devices to crack or break, allowing unfiltered sunlight to pass through to the eye. The apparent field of each eyepiece that Celestron manufactures is found in the Celestron Accessory Catalog. For example, if using your telescope from Los Angeles, you would set the scale to 34 degrees.
Other telescopes, known as reflectors, use mirrors. Terminator The boun dary line between the light and dark portion of the moon or a planet. Each alignment method is discussed in detail below. Simple and friendly to use, the NexStar is up and running after locating just three bright objects. Slew Limits — Sets the limits in altitude that the telescope can slew without displaying a warning message.
Equatorial mount A telescope mounting in which the instrument is set upon an axis which is parallel to the axis of the Earth; the angle of the axis must be equal to the observer's latitude. It is done with the camera attached to the telescope without an eyepiece or camera lens in place. I purchased a Celestron Omni 2x Barlow. Advertisement Print version Many people prefer to read the documents not on the screen, but in the printed version. Simple and friendly to use, the NexStar is up and running after locating just three bright objects. To attach your camera you need the Celestron T- Adapter 93633-A and a T-Ring for your specific camera i.
Use this manual in conjunction with the on-screen instructions provided by the hand control. The telescope can be controlled at nine different speed rates. With automatic slewing to over 18,000 objects, and common sense menu descriptions, even a beginner can master its variety of features in just a few observing sessions. Overall Depth - Front to Back: -13 Inches. All other accessories, both visual and photographic with the exception of Barlow lenses , thread onto the skylight filter. Although this is the maximum useful magnification, most observing is done in the range of 20 to 35 power for every inch of aperture which is 100 to 175 times for the NexStar telescope. Our eyes are very poor at processing colors in the dark, so deep sky objects like nebulae and galaxies will be seen in shades of grey, or black-and-white.
Because of diffraction, there is a limit to the minimum angle, resolution. Telescope tracking motors drive the telescope at this rate. Products or instructio ns may ch ange without notice or obligation. Call Celestron at 310 328-9560 to receive the number to be displayed on the outside of your shipping container. If the finderscope has been properly aligned with the telescope tube, the alignment star should now be visible inside the field of view of the eyepiece.

However, there are a few things to consider before using your telescope that will ensure your safety and protect your equipment. Those photos are the result of long exposure astrophotography and the complete absence of atmospheric turbulence. With automatic slewing to nearly 40,000 objects, and common sense menu descriptions, even a beginner can master its variety of features in just a few observing sessions. If you are new to astronomy, you may wish to start off by using the NexStar's built-in Sky Tour feature, which commands the NexStar to find the most interesting objects in the sky and automatically slews to each one. Simple and friendly to use, the NexStar is up and running after locating just three bright objects. The focal length divided by the aperture of the mirror or lens is termed the focal ratio. Great Telescope for 3 years now.
Use the up and down scroll keys 10 to select the star you wish to use for the first alignment star. To set up the tripod: 1. Never leave the telescope unsupervised, either when children are present or adults who may not be familiar with the correct operating procedures of your telescope. Also, I was able to put it together in less than 10 minutes. Permanent and irreversible eye damage may result. With those items, I'd give it 5! Solar Used for tracking the Sun when solar obse.

Products or instructions may change without notice or obligation. Planets - All 8 planets in our Solar System plus the Sun. When working with any optical instrument, there are a few things to remember to ensure you get the best possible image. By default, the cord wrap feature is turned off when the telescope is aligned in altazimuth and turn on when aligned on a wedge. When the telescope's polar axis is pointed at the celestial pole, it is parallel to the Earth's rotational axis. The slew limits prevent the telescope tube from slewing to an object below the horizon.
