Product description

More about the series NexStar SLT...

This set consists of

The additional eyepiece together with the two eyepieces included with telescope mean you have three magnifications available. The Moon filter increases the contrast in lunar observing and reduces the intensity of bright moonlight. The high-quality power supply is particularly useful, allowing you to use the telescope without batteries.

The brand new NexStar SLT series with SkyAlign technology offers computerized GoTo telescopes with a multilingual menu and huge database, as well as being excellent value for money.

The fully assembled ready-to-use tripod and quick-release couplings for connection to the fork mount, as well as the OTA on a fork arm allow setting up in just a few minutes - without the need of any tools!

A huge range of celestial objects are available to observe, and the computer can also select the best objects to observe month by month.

Intelligent design

Operation of precision servo motors and electronic position encoders is possible either via 8 AA batteries, 12V/2A power supply ( 821008), power tank ( 821040 for 7AH or 821043 for 17AH) or with a car battery cable ( 821016). The Internet upgradable NexStar hand controller lets you find up to 4000 objects at the touch of a button.

Celestron's revolutionary SkyAlign *

Thanks to 'SkyAlign', you no longer need to know either the positions or names of any stars. Simply type in the date and the time, select the nearest location from the list provided, do a three star alignment (the Sun, Moon and planets may also be used for this) and confirm with the press of a button.

The processor calculates the position of all visible celestial objects within seconds! With Solar system alignment, you simply select the Sun as a reference object (BUT ONLY USING A SAFE SOLAR FILTER AT THE FRONT OF THE TELESCOPE) and you can then even find the brighter stars and planets in the middle of the day - great for working with children.

Standard equipment and accessories include:

- computerized hand control with over 4,000 objects in the database

- quickly detachable, single-arm fork mount, quick mounting of the OTA and accessory tray without tools

- SkyAlign allows alignment on the basis of any three bright celestial objects, which makes polar alignment a breeze

- 'The Sky' level 1 planetarium software and NSOL telescope control software for the control of your computer are included in delivery

The AC 90/910 telescope:

A high-quality refractor at a reasonable price is still rather hard to find as refractors have always been much more expensive than any other type of telescope. But regular improvements in the technology have been lowering these astronomical prices for a while now. The result is a high-quality telescope at a remarkable price. This telescope is powerful enough to keep beginners occupied for many years to come. You will be able to see great images of the Moon and planets, as well as many deep sky objects. With an aperture of 90mm, this OTA can provide useful magnifications of up to 180X and, with its 910mm focal length, gives an excellent F10.1 aperture ratio.

The advantages in a nutshell:

  • good value for money
  • light OTA, eminently portable
  • makes an excellent guide scope
