All those issues will cause bad tracking or inaccurate auto-star finder. That's also a good time to check for broken gear teeth, split screw anchors in the ba se assembly, end play in the worm drive, and so on. The wires fray or sever and the entire scope base needs disassembled and depth of repair depends how badly the wires are damaged. Worse yet is when the 4 wires that run through the partially hollow RA locking bolt. Fix is easy if you know what you are doing to repair it. Most common failure is the broken Declination locking knob since it's plastic and snaps. ![]() Still they suffer from drive mechanism failures of different sorts. The latter three are Muskatov design and much better optically and made in the USA. All ETX models are not equal, by far! The ETX 60, 70,80 are refractor types and built cheaper than the larger objective ETX 90, 105, 125 models. The ETX line is a good line of amateur scopes. With the telescope placed in the altazimuth mode on a table, astronomical object-tracking may be accomplished automatically, after a quick and easy 2-minute alignment of Meade Autostar to the sky.Ĭordless Field Operation: The drive base of Meade ETX 90 AT Computer Telescope accepts eight (user-supplied) AA-batteries that power the telescope for about 20 hours of normal usage, negating any requirement for an external power source in the field.Optically pretty decent - mechanical reliability/accuracy is questionable #Meade autostar etx90 alignment youtube full#Meade #884 Deluxe Field Tripod: Constructed of strong, lightweight steel, the full length Meade ETX Telescope Tripod #884 provides a rigid mounting platform for virtually any ETX observing application, including astrophotography.įork Mounts with Standard-Equipment Dual-Axis Drive System and Meade #497 Autostar Controller: The rigid fork mountings of Meade ETX-90 Maksutov-Cassegrain Telescope 35140321 include high-torque DC motors on both telescope axes, permitting electronic operation from the standard-equipment Meade Autostar Controller. #Meade autostar etx90 alignment youtube plus#Meade #497 Autostar Computer Controller: Included with Meade ETX 90 AT Telescope the patented Meade Autostar Controller #497 brings automatic GO TO operation, plus dozens of additional menu options, to your fingertips, with a database of more than 30,000 celestial objects, including 5,386 galaxies, nebulae and star clusters from the Index Catalog (IC) 7,840 objects from the New General Catalog (NGC) 110 Messier objects the major planets from Mercury to Pluto and more. Observe the continually changing cloud-belt patterns on the surface of the planet Jupiter shadows cast on to Jupiter as one of its four principal satellites transits the planet's disc the magnificent ring system and satellites of Saturn as well as dusky markings and the ring-shadow on the surface of Saturn Moon craters by the hundred, plus lunar rilles, mountain ranges, and fault lines, all visible in brilliant, high-resolution, high-contrast detail the variable phases of the planets Mercury and Venus prominent features on the surface of Mars. #Meade autostar etx90 alignment youtube portable#Or, for the advanced astronomer who already owns a larger instrument, the Meade ETX-90AT Telescope is the perfect diffraction-limited, ultra portable field telescope. Meade ETX Telescopes are instruments fully capable of growing with your interest and are ideal for both the casual observer and serious astronomer alike.įor the casual or beginning observer the Meade ETX-90AT UHTC Autostar Telescope may be all the telescope ever required. ![]() You will observe the feather structure of an eagle from 50 yards or study the rings of Saturn from a distance of 800 million miles, focus beyond the Solar System and observe majestic nebulae, ancient star clusters, remote galaxies, and even stars recently discovered to have planets orbiting about them. Meade ETX-90AT UHTC Telescope with Autostar reveals nature in an ever-expanding level of detail. ![]() ![]() With Meade Autostar Computer Controller, automatic tracking of celestial objects, and diffraction-limited imaging, a Meade ETX-90 AT Telescope may be all the telescope ever required by many terrestrial and astronomical observers. Meade ETX Telescopes are extremely versatile, high-resolution telescopes with features similar to those once available only with larger and more specialized imaging systems. Meade ETX 90 AT UHTC GoTo Computer Telescope could be your Personal Window to the Universe. ![]()
