A Barlow lens is used to increase the magnification of each eyepiece. First insert the Barlow 3X lens in the telescope’s eyepiece holder, then the eyepiece itself. Secure the lens using thumbnail screws. The total magnification will be 135X when a 20 mm eyepiece (45X) and a 3X Barlow lens are used together.

Some words of caution on magnification. Although the theoretical power or magnification of a telescope is virtually limitless, there are practical limits, such as the earth's atmosphere. Every telescope has a useful magnification limit of about 2X per millimeter of aperture. This comes to 140X for the 900X70. Moderate magnifications are what give the best views. It is better to view a small, but bright and detailed image than a dim, unclear, oversized image.

5. Maintenance

If you give your telescope reasonable care, it will last a lifetime. Store it in a clean, dry, dust free place, safe from rapid changes in temperature and humidity. Do not store the telescope outdoors,

although storage in a garage or shed is OK. Small components like eyepieces and other accessories should be kept in a protective box or storage case. Keep the caps on the front of the telescope and on the focuser drawtube when not in use.

Your 900X70 telescope requires very little mechanical maintenance. The optical tube is aluminum and has a smooth painted finish that is fairly scratch resistant. If a scratch does appear, it will not harm the telescope.

Cleaning Lenses

Any quality optical lens cleaning tissue and optical lens cleaning fluid specifically designed for multi-coated optics can be used to clean the objective lens and the exposed lenses of your eyepieces. Never use regular glass cleaner or cleaning fluid designed for eyeglasses.

Before cleaning with fluid and tissue, blow any loose particles off the lens with a blower bulb or compressed air. Then apply some cleaning fluid to a tissue, never directly on the optics. Wipe the lens gently in a circular motion, then remove any excess fluid with a fresh lens tissue. Oily fingerprints and smudges may be removed using this method. Use caution— rubbing too hard may scratch the lens. For the larger surface of the objective lens, clean only a small area at a time, using a fresh lens tissue on each area. Never reuse tissues.

6001, 6002 specifications

The iOptron 6002 and 6001 are advanced equatorial mounts designed for both amateur and professional astronomers seeking reliable tracking and precision in their astronomical observations. Renowned for their robust construction and advanced technology, these mounts enable users to fully exploit their telescopes' capabilities, ensuring a rich stargazing experience.

Both models feature iOptron’s innovative GoTo technology, which allows users to locate and track celestial objects automatically. With an extensive database of over 200,000 celestial objects, the user can easily choose their target, and the mount will accurately position the telescope. The built-in GPS feature enhances usability, automatically determining the observer's location and the current time, thus simplifying the setup process.

One of the standout characteristics of the iOptron 6002 and 6001 is their impressive payload capacity. The mounts are engineered to handle a variety of telescope sizes and weights, enabling users to attach larger optical tubes while maintaining optimal stability. The robust construction ensures minimal vibrations during observations, providing clearer images and reduced tracking errors.

The iOptron mounts are equipped with dual-axis tracking motors, providing smooth movement across the sky. The high-precision encoders enhance the tracking accuracy of celestial objects, while the internal battery ensures the mounts can operate for extended periods without needing an external power source. This feature makes the iOptron mounts particularly attractive for remote observations and extended astro-photography sessions.

Another notable technology incorporated in these mounts is the user-friendly controller. The intelligent hand controller is designed with a graphical interface that simplifies navigation through the extensive database of star catalogs and observation objects. Users can enjoy customizable options and easily update the firmware via USB connection to keep the system at its best performance.

With their compact design and portability, the iOptron 6002 and 6001 models are ideal for astronomers who wish to take their observatories on the go. The set-up process is quick and straightforward, allowing users to focus more on their observations rather than on complicated installations.

In summary, the iOptron 6002 and 6001 are high-performance mounts equipped with cutting-edge technology and features. From their robust construction, remarkable payload capacity, reliable tracking, and user-friendly controls, these mounts provide an exceptional platform for all astronomy enthusiasts, elevating the stargazing experience to new heights.
