Summary: Powerful and inexpensive, but it's a computer - be prepared
Review: "Goto" Telescopes and controllers have been around for quite a number of years now, but are normally very expensive. The Autostar has 95% of the functionality of the expensive hardware at a small fraction of their price.
I think that Meade has done an excellent job of making this device user-friendly. However, it's a powerful tool, and it will take some serious attention on your part to make it work to even a fraction of it's potential. One big advantage the Autostar has over the competitors "goto" controller is that fact that Meade is constantly updating and improving the firmware. Get the #505 cable, or make your own for a few bucks and you'll also be able to load in newly discovered comets or customized sky tours.Although many novices will find it confusing, the Autostar can actually be easier to use than the more advanced and higher priced controllers used on much more expensive telescopes.

Summary: This is a SCIENTIFIC INSTRUMENT, people!
Review: Definitely NOT for the plain John Doe. You will not be able to align this correctly on the first, second, or third try. You will be frustrated and angry. Try not to kick the telescope, ... If you're thinking about hosting an astronomy party, make sure you summon John Glenn before making calls... I think Meade should have devised an easier way to get this to work. Like... just pointing it to the moon, centering, and there. And then Jupiter, which is bright. The manual is BAD. If I can ever get this to work I will put more stars on this review. Otherwise, I recommend you lower your expectations on this marvel of science. Lower them to the floor. Hire a manual translator, then give Autostar a shot. And email me. Let's laugh at it all together.
-*PS- If you already have the ETX telescope, definitely get this. The menu gives you the names of hundreds of objects you will want see on your telescope. You will be AMAZED at the great number of things there are out there to see. And that's about it, because finding them is impossible!

Review: easy to use and great for educational purposes June 14, 2000
The Autostar is so decadent! I almost feel guilty for using it. But it is so easy to use and enhances the ETX-90EC scope so much that I use it all the time. Set-up and locating the reference stars is fairly easy, and it is so much fun to take the tour of the sky. I've used this several times in an educational setting and it is fantastic for quickly pointing out stars and other celestial objects. In addition, it expands on the standard controller, giving you nine variable speeds instead of the standard four. Once you use the Autostar you will never go back.

Summary: Not as difficult as it's made out to be
Review: I first grew acquainted with Autostar about 6 months ago (albeit the 494 model) on the ETX-70 AT, and had some accuracy issues the first few times I used it. They were easily fixed, though, with a good drive training (on a power pole about a mile and a half away) and careful motor calibration. That was in May, and except for when the batteries are low, I haven't really had problems since. In late June, I moved up to the LXD-55 6 inch Shmidt-Newtonian (which uses the same 497 Autostar as the ETX line), and after one repair call for a motor problem it has easily met my expectations for visual work. While the short focus Newtonian may have a wider field of view and a much better sigting scope than the ETX's (as well as significantly more aperture for under $800), keep in mind that it must be POLAR aligned which is MUCH more difficult than an ETX Alt-Az procedure. I usually cheat and use Polaris instead of the true North Pole, but my accuracy is still predictibly within 30-45 arcminutes (1/2-3/4 of a degree or easily within the view of a 26mm eyepiece) on 90-95 percent of the slews with a rough setup. Here's how to get the thing to work the way its supposed to on an ETX when you first get it. Do the first 6 in daylight to make the setup easier:
*Skip Time for now
*Enter Date (if you will observe that night) and nearest city
*Enter your observing site name and adjust your latitude and longitude (use topozone.com or a topomap to find your location to the nearest minute (60th of a degree)) for your site
*Train the drive using a distant (1 mile or more) object. Procedure is in manual. If done well you should not need to do it again for months
*calibrate motors
*turn off telescope
That night (or any night):
*set up and level telescope (use torpedo level and rotate tube to check level). This is only necessary if you know that your site is significantly (5 degrees or more) off or your tripod is set to less than maximum height
*Aim north at Polaris (the North Star). Do NOT use a compass-it is often as much as 14 degrees off from true north. Use the two stars at the end of the big dipper to aim at the first bright-ish star at the tail of the little dipper. Align finder scope if necessary her.
*level tube by bringing it straight down to horizontal
*start alignment (easy at first, two star when you know the sky better). push the down scroll button if the star is behind a tree or other barrier. center in the eyepiece, not just the sighting scope. Press enter. Repeat for other star (preferably far from the first one-the farther the better)
*Enjoy! For the long term, get a star atlas or astronomy program and a range of good eyepieces/filters. I deducted a star for the fact that Autostar displays thousands of objects nightly that are below the horizon and that the NGC and IC catalogs are nearly worthless unless you have a comprehensive atlas and know the catalog number of the object(s) you are looking for.

Summary: Autostar for Dummies? Where is it? I'll buy.
Review: I'm a rank astronomy novice. I read the Autostar manual word for word twice before I dared to hook it to my ETX-90 scope. So far the Autostar is far far too complicated for this CPA, MBA to understand. The computer seems very slow to respond to commands. Maybe if I read the Autostar manual another dozen times I'll figure some of it out. Meanwhile I'll use the simple controller that came with my scope. I understand that remote completely.

Summary: Find stars you never knew existed
Review: The AstroStar is a great ETX accessory. My favorite feature is its "give me a tour of what's good tonight." It is also great for figuring out what your looking at with its "identify this" feature. The only drawback is you have to be really careful aligning the scope initially to get it to work. The instructions weren't that clear between the scope, the tripod, and the Astrostar book. My recommendations to you, remember to align the scope to true north (i hold a compass on the lens tube), use a bubble level to level the tube, set your watch to the second on the nights you go out, and make sure the viewfinder and scope are well aligned. Do these four things and I guarantee you'll have a great night of viewing.

Review: There are two schools of thought on the use of go-to telescopes. One school believing that it takes away all the skill and fun from astronomy. however, I'm a believer in the other viewpoint. I think go-to capability opens up astronomy to the masses and brings the universe just that little bit closer to everyone. I purchased the Autostar for my ETX about a year ago and it has had extensive use. Out of the many many times I have used the autostar with the scope, I estimate it has performed as desired on 90% of my viewing nights. Unusually, I seem to be able to align my ETX rather easily depsite the fact that many people have difficulty. I think I have had luck on my side as the ETX, while a beautiful scope, can be a little temperamental. Even after doing a quick and rough alignment, like pointing it in the general direction of due North, without using a compass, I still get very accurate results with the autostar. I even changed locations the other day, moving from Auckland to Taupo, (some 3 hrs travel distance by car) and inadvertantly used the Auckland co-ordinates while viewing in Taupo. Suprisingly after alignment, I still got accurate positioning from the autostar. Once you get the hang of the menu system the autostar is really quite simple to navigate around. The amount of data is staggering, but given the size of the playground, it's not suprising. The unit itself is comfortable to hold and the adjustable brightness makes reading the screen simple in the dark. I havn't found the built in red light at the top of the unit very good as it is just too dim to make out charts etc. The trusty old torchlight with red nail polish on the lens is hard to beat on that score. I suggest that if you are operating from a tripod, you attach something to the back of your autostar that lets you hang it up on the tripod when you are not using it. Otherwise it can dangle around and get in the way. On a couple of occassions I have had the unit fail to operate correctly or reset itself. These have been far and few between, and readily fixed itself. Ultimately the Autostar is a computer so an occasional reset is not entirely unexpected. One minor problem I am experiencing at the moment is the scrolling text on the lower line of the display panel is tending to fade a little the faster it scrolls. This has occured since I started using a power adapter for the scope so this will need investigating. This however is only a minor niggle. If you have any concerns about your Autostar consult
the best resource on the net for the autostar, Mike Weasners site. The Autostar is highly recommended and really an essential purchase to go along with your ETX. Clear skies everyone and happy alignments.
