A great all-round, reliable and robust telescope, sort very sad to sell it but a change in hobbies means I don’t get to use it as much as I’d like to.

Cash on collection please, and you will need to collect in person as it’s not practical to post.

Any questions, please feel free to call on 07590696812.

The specification is as follows:

Celestron NexStar8 Telescope with Tripod

Celestron developed this telescope in order to provide a relatively affordable, very easy to use “Go-To” computer controlled telescope with better rigidity than the Celestar 8 telescope. This will be a telescope to be considered by those who are interested primarily in visual applications, or for the photography of terrestrial objects including birds or other wildlife at great distances. The ability to precisely move the telescope up or down or left or right (without the astronomical clock drive continuously moving the telescope) makes this a platform to be considered for terrestrial and other applications where exact positioning is required.

Electronics and Computer Software Features: 

The electronics control system includes a totally cordless, smooth moving and nearly silent drive system. User input and 16 bit computer feedback are provided through the NexStar Keypad Controller. The controller incorporates a dual line, 16 character Liquid Crystal Display (LCD) display which is back lit for easy use in the dark.

The NexStar 8 operating system provisions include:

– database storing the location of 18,473 objects: includes entries from the Messier, NGC and Caldwell catalogs as well as planets, and selected SAO objects.

– storage memory for 25 user programmable objects: up to 5 terrestrial, and up to 20 astronomical.

– storage memory for 10 user programmable observing sites (input at site, or by entering longitude and latitude in advance).

– Tour Function: selects the best and most spectacular objects available for you to observe.

four astronomical tracking rates: King, Sidereal, Lunar and Solar.

– nine slew or correction speeds: 6.5 degrees per second, 3 Deg./Sec., 1.5 Deg./Sec., 128X Sidereal, 64X, 16X, 8X, 2X, 1X.

Cord Wrap protection: stops the telescope from rotating more than 360 degrees thereby preventing the wrapping an any external cord around the telescope. This menu selection may be disabled by the user when desired such as when operating the telescope from internal batteries.

Anti Backlash: All mechanical gears have a certain amount of backlash or play between the gears. This play is evident by how long it takes for a star to move in the eyepiece when the hand control arrow buttons are pressed (especially when changing directions). 

The anti-backlash features allows the user to compensate for backlash by inputting a value which quickly rewinds the motors just enough to eliminate the play between gears. The amount of compensation needed depends on the slewing rate selected; the slower the slewing rate the longer it will take for the star to appear to move in the eyepiece. Therefore, the anti-backlash compensation will have to be set higher. 

You will need to experiment with different values; a value between 20 and 50 is usually best for most visual observing, whereas a higher value may be necessary for photographic guiding.
