Meade ACF-SC 203/2034 UHTC LX90 GoTo telescope without tripod

LX90 mount:

Now it is even easier to observe the starry sky, even without knowledge... Assemble it and enjoy! All you have to do is select a reference star from those suggested and confirm its position. The mount works on the same principle as professional observatories. Your AutoStar Handbox device (included) has stored the coordinates of about 30,000 astronomical objects in his memory: 13,235 Deep Sky objects, 16,888 stars arranged by name and SAO number, 8 planets, the Moon, 26 asteroids, 15 comets, etc. Additionally, you can include 200 objects of your choice . The system quickly and silently locates and positions itself towards these objects: the GoTo function works by 9 different positioning speeds : 6.5°/s, 3°/s, 1.5°/s or the stellar speeds 128x, 64x, 16x, 8x, 2x and 1x.

The AutoStar Handbox software is updated online. In addition, data banks on comets, asteroids, satellites, etc. They can be downloaded from the Meade website. This way, you will have updated coordinates and the LX90 will be as precise as the first day.

A 125mm diameter worm screw in both axes ensures precise tracking of objects even during long astrophotography sessions.

The frame is light, but provides great stability. The height-adjustable tripod also contributes to the stability of the equipment. Compatible with altazimuthal or parallactic mount.

AutoStar Suite software (included) allows you to control the LX90 from a computer.

Connection for the autoguide is optional. It works by power supply, with 12V batteries or through the car battery.

Includes:

• AutoStar Handbox with software.
• GoTo function with 30,223 objects.

With its stylish optics Schmidt-Cassegrain This telescope leaves nothing to the imagination. And SC telescopes are suitable for any application . It doesn't matter if you are looking for planets, distant nebulae or galaxies, and it doesn't matter if you want to observe or photograph them, because with an SC everything is possible.

The compact optics guarantee limited leverage effect on the frame and is perfect for transporting. As focusing is carried out internally, the focus plane can be adjusted so well that the perfect sharpness can be found even for astrophotography accessories.

SC telescopes are equipped with a spherical main mirror. This is a disadvantage, because only parabolic mirrors, such as those found in Newton telescopes, bend light rays off-axis toward the focal point. That is why the optical designer Bernhard Schmidt (1879-1935) developed a special correction plate that is placed on the front of the tube. Equipped with the Schmidt plate, the SC telescopes display a sharp image free of spherical aberration. Furthermore, by being closed in this way, the main mirror is protected from dirt and unwanted turbulence caused by the air.

In the center of the correction plate there is a secondary mirror that returns light to the primary mirror and then, through a hole, reaches the back of the tube. This position of the light output owes its name to Laurent Cassegrain (1629-1693) . Professional telescopes take advantage of this design advantage: heavier accessories do not exert leverage and the telescope's viewfinder remains intact, even when viewing objects of different heights. That's why no ladder is needed and even the little ones can take a look comfortably and safely, something not inconsiderable for those watching from the balcony!

ACF ( Advanced Coma-free ) coma-free optical tubes: Meade's ACF optical design reduces the image errors typical of all mirror tubes, so stars look sharp right down to their outline, without trail-like distortions more reminiscent of a comet. The image looks flatter than with classic Schmidt-Cassegrain telescopes. ACF optics are spatially useful for astrophotography.

Ultralight Transmission Coatings UHTC ( Ultra-High Transmission Coatings ): This special multi-layer treatment of the front corrective plate guarantees up to 15% more light transmittance. The result is clearer star clusters, finer details on nebulous objects, and better-defined surfaces on planets.

manual control AudioStar offers a database of 30,000 celestial objects. By simply pointing it at the sky, AudioStar can point the telescope at these objects and keep them centered on the target (obviously, as long as they are above the horizon). This feature, called GoTo, is accompanied by other functionalities, such as guided tours, position indicator and PC connection.

One of the most notable features of the AudioStar control is the integrated speaker. The Astronomer Inside technology is an astronomer who offers more than four hours of voice broadcast (only in English) with interesting data about the celestial objects captured by the control.
