Skywatcher 130 eq 2

Finalmente deciso!! Dopo decine di email inviate ad altrettanti astrofili ho fatto la mia scelta: Skywatcher 130 eq 2 riflessore.

Ora basta avere voglia uno di questi giorni di andare in negozio a fare l'acquisto.

MEADE ETX-70AT ...E questo? Che ve ne pare?
Ho trovato in rete anche questo Meade.. Per iniziare si dice sia buono anche se sarebbe meglio il fratellino maggiore etx-90 che però costa estremamente troppo per le mie tasche..



MEADE ETX-70AT

Let Meade high-resolution optics and revolutionary AutostarTM capability take you on an automated guided tour of the Solar System, the Galaxy, and beyond.

Now even the most novice amateur astronomer can locate and explore the planets, galaxies, and nebulae, as well as star clusters, asteroids, and comets, all at the push of a button. Because, "more than any other telescope, the Meade ETX has revolutionized amateur astronomy. Since it was introduced in 1996 it has become the standard by which others are judged, combining low price with optical excellence, a solid mounting, and...computerized 'GO TO' facilities."* Meade ETX Astro Telescopes, in four apertures, bring the full range of celestial images to your eye with astonishing levels of clarity, resolution, and definition.

ETX-70AT Astro Telescope

All of the major planets except Pluto are easily observable through the ETX-70AT. Study Saturn and its ring system; the primary cloud belts of Jupiter as well as its four major satellites; the Moonlike phases of Mercury and Venus; prominent features on Mars; the starlike images of the distant planets Uranus and Neptune. The Moon stands out in stark, almost three-dimensional detail - craters, mountain ranges, and fault lines. In our galaxy the telescope displays hundreds of nebulae, star clusters, double and multiple stars,


In decades past, the astronomy world has bemoaned the lack of an effective, affordable beginner's telescope...the Meade ETX-70AT refractor is perhaps the first innovative beginner's telescope for the present generation. And Meade surmounted significant challenges to produce them: Rather than churning out merely a good set of optics, [the ETX-70AT] provides a user-friendly mini-observatory for the computer age...After using the telescope for a few hours, the sea change in how technology will affect beginning observers struck me hard...the potential of the computerized generation is startling. With the ETX-70AT, in a matter of minutes, I could see two or three dozen objects in rapid succession, finding them effortlessly and comparing their appearances much more effectively because they were so easy to locate."
- from the review in Astronomy, February, 2001.

and variable stars - plus dozens of external galaxies in all their variations of form and structure. See the Autostar listing on the facing page for a complete compilation of database objects.

Terrestrial Observing: The Meade ETX-70AT also makes an excellent land-view instrument for the birdwatcher, the naturalist, or for the home with a view. Image quality and resolution typically far exceed levels normally expected of terrestrial telescopes. Terrestrial observers quickly appreciate the advantages afforded by the Autostar hand controller (see below). Using Autostar, many land objects can be readily followed, or tracked, from a distance, using one of nine selectable speeds.

* Quoted from Using the Meade ETX by Mike Weasner, Springer-Verlag, 2002.

Fork Mount with Dual-Axis Drive System: In conjunction with the telescope's Autostar hand controller, precision worm gear systems on each axis permit smooth pushbutton motions of the telescope. Integrated to one of the fork arms, the telescope's control panel serves as a central connection point for the hand controller (the HBX port), as well as for the RS-232 serial interface adapter (the AUX port), an adapter included with the optional #506 AstroFinder Software and Cable Connector Kit. Using the RS-232 interface, new or revised software may be downloaded through your PC to the telescope; the positions of Earth satellites may be updated for their observation

The Meade ETX-70AT is provided as standard equipment with all equipment shown, including the full-length #882 Field Tripod.
through the telescope; and the positions of newly-discovered objects, such as comets, may be accessed by Autostar.

Optical System: The ETX-70AT includes a multi-coated, achromatic objective lens of exclusive Meade design and manufactured of Grade-A crown and flint optical glass components. The lens yields razor-sharp images of astronomical and terrestrial subjects.

Flip-Mirror System: For observing in the standard 90° position, flip the internal, optical flat mirror "up." For terrestrial observing with the optional #933 45° Erecting Prism or for photography with the optional #64ST T-Adapter, flip the mirror "down."


The Meade ETX-70AT Optical System

Optical System Chart

In the optical design of ETX-70AT, light enters from the right through a 2-element objective lens and travels to a focus at the focal plane. Field stops internal to the optical tube prevent off-axis light from reaching the focal plane, thereby enhancing image contrast.
ETX-70AT with Autostar
The Meade ETX-70AT Astro Telescope, shown with standard-equipment #494 Autostar Computer Controller and set up for tabletop astronomy.
Specifications: ETX-70AT Astro Telescope - Includes achromatic refractor optical tube assembly (D = 70mm, F = 350mm, f/5) with multi-layer optical coatings; internal flip-mirror system for either straight-through or 90° observing position; steel-reinforced ABS fork mount with electric slow-motion controls, setting circles, and locks on both axes; electronic control panel; 9-speed (2x sidereal through 4.5°/sec.) dual-axis motor drive system with #494 Autostar computer controller; sidereal-rate tracking; internal battery compartment accepting six (user-supplied) AA-size batteries; MA9mm (39X) and MA25mm (14X) multi-coated eyepieces; #882 Field Tripod; operating instructions.

Ultraportable and Simple to Use: Easy to carry to any observing location, whether a distant mountaintop or your own back yard, the Meade ETX-70AT telescope brings the excitement of astronomy to users of any age. Just place the telescope on any flat surface (or use the standard-equipment field tripod), do a quick, easy alignment of the telescope's computer to the sky, and start observing. Six internal (user-supplied) AA-batteries power the ETX-70AT for about 20 hours.

Autostar Hand Controller - "the greatest happening in amateur astronomy yet." For all of their advanced imaging capabilities, portability, ease of use, and contemporary cosmetic design, Meade ETX telescopes are above all uniquely defined by the revolutionary Autostar hand controller.

Included as standard equipment with the ETX-70AT, the #494 Autostar controller permits the automatic location of over 1400 celestial objects, including all of the following objects located in the telescope's onboard database:

Solar System
Planets 8
Moon 1
Asteroids 26
Comets 15
Constellation 88
Deep-Sky
Named Objects 66
Galaxies 74
Diffuse Nebulae 31
Planetary Nebulae 19
Quasars 11
Caldwell Objects 109
Messier Objects 110
Stars
Named Stars 79
Double Stars 395
Variable Stars 189
SAO Stars 200
Earth Satellites 50
____
Total Objects 1471

Just enter the object you wish to observe on to the Autostar display, press GO TO, and watch as the telescope moves rapidly in seconds to place the object in the telescope's field of view. One observing session validates the prediction made by Sky & Telescope that "The ETX/Autostar concept will go down as the greatest happening in amateur astronomy yet."

Objects stored in the #494 Autostar's database include the entire range of celestial phenomena and are designed to keep the active observer busy for many a starlit evening.

The above database listing has been specifically chosen as suitable for observing with the ETX-70AT and provides an excellent introduction to the diversity of astronomical objects visible through the telescope.

In addition to its object-locating capabilities Autostar permits pushbutton centering of objects within the telescopic field at any of nine selectable speeds. Once Autostar locates an object, it directs the telescope automatically to track the object across the sky, compensating fully and precisely for the effects of the Earth's axial rotation.

Compleanno Matteo un'avventura
Sfatato il problema neve con una bella pioggerellina e un innalzamento della temperatura siamo potuti andare a cena per il compleanno di Matteo.

Tutto ok, tutto buonissimo (mega costata di sorana più grande dello stomaco) e tante ma tante risate!
Al momento della torta ce ne arriva al tavolo una con le candeline rosa e il numero 26..
peccato che matteo ne compisse 25!
Insomma alla fine arriva la cameriera..a candelina ormai già accesa e ci dice - questa è di Mazzocco! - super risate e in quel momento (solo in quel momento Matteo ricorda che la sua torta era rettangolare...quella li tonda!
Fortuna che non avevamo tagliato le fette..
Alla fine agli altri (i Mazzocco per capirci) totalmente inconsapevoli arriva la torta con tanto di candelina già accesa..altrimenti si accorgevano che era stata usata!!
De hi hi ho uh
