Well, IDW/A.A really wants the thread to wander away from the questions he won't answer, because he knows they prove his assertion utterly false. Else, why not answer Dr. Astro's question? Hey IDW, when was the last time the LX200 Classic had an update of any kind?
Quoting: Dr. Astro Or mine? And yet, out of the box, with no updates whatsoever, they track flawlessly.
Updates are good -- they fix bugs and add objects to the database. But the models I mentioned have no mechanisms whatsoever without removing the chips altogether. Yet, they work. Can you *explain* that, IDW/A.A? Do you believe that all telescopes manufactured before 2000 are unable to track the heavens?
Autostar has been good about updates; there was one in January 2013 and the earlier version is from August 2012. Both, of course, require connecting the controller to a computer, but the telescopes will track without the upgrade just fine.
Celestron hasn't issued an update since 2007. Does that mean all Celestron GOTO telescopes are now broken?
How would a STARWHEEL work if there was unpredicted motions of the Earth? How do you IMAGINE it would get updated? Why can you use a Starwheel from 30 years ago and still find constellations rising and setting on time?
Quoting: Anonymous Coward 74444 Or this? Any individual who has any experience in astronomy knows that because the position of the Earth relative to the universe is moving in several different vectors, a few which are unknowns, the chandler wobble is totally unpredictable , there is no such thing as an immovable mount and that the Gregorian method of timekeeping is grossly inaccurate, that it would be impossible for clockwork or computer software to inaccurately locate celestial objects over more than few months period of time at best.
Quoting: Anonymous Astrophysicist 1173362 How are eclipses, transits, and occultations predicted so accurately, then -- some *centuries* in advance? Or even these? I think it relevant to mention that the strong forces BOTH gravitation and electromagnetic present in the galactic plane will most assuredly make predicting the trajectory of asteroids impossible past a few days out. Many of these asteroids if not most are composed mainly of iron, and magnetic fields deflect iron. THIS HAS NEVER BEEN CONSIDERED CALCULATING THE TRAJECTORY OF ASTEROIDS AND UNTIL NOW THE ELECTROMAGNETIC FORCES WERE SO INSIGNIFICANT AS TO HAVE LITTLE EFFECT. THIS IS NO LONGER THE CASE! UP UNTIL NOW ONLY TRAJECTORY AND GRAVITATIONAL INFLUENCES HAVE BEEN USED TO CALCULATE FUTURE TRAJECTORIES, AND THIS IS THE PRIMARY REASON WHY 'THEY' WILL NO LONGER SEE THEM COMING BEYOND A FEW WEEKS OUT.
Quoting: Anonymous Astrophysicist 1373903 What evidence can you give that Newton's numbers have failed because of unpredicted electromagnetic forces? How are such objects tracked *now?* Once the orbital elements are known, you can track an object whenever you want to, its just a matter of plugging in numbers. Hell, there are apps on your Iphone or Android that do it, and they cost *nothing.* *Newton* could do it, why can't you? He seemingly can only reply with Jim Carrey emoticons. He wants merely to chat about the weather. By the way, the prediction of 90 degrees on Christmas day in the northern states was very conservative, and will mist likely be worst. By that time it won't matter anyway, because there will be no way to say "I told you so", no do i revel in being able to beat my chest and take credit for predicting that probability.
Quoting: A. Astro-physicist 1347517 Alas, that doesn't do him much good, either.
