Subject: Re: Meade ETX-125 and #883 tripod Sent: Sunday, December 30, 2001 13:39:22 From: email@example.com (Clay Sherrod) To: Jerod Hello Jerod and thanks for the nice comments. I assume you mean mounting the plate directly onto the base and then using the base flat on a solid surface rather than onto a tripod?? If so, there is little to gain... However, my first advice in this regard is to TAKE OFF the rubber feet on the base as the are the #1 source of major - I mean major - vibration and shakes in the ETX 125. If you take those off, you will have a MUCH more solidly mounted scope. I suspect that the slick surface of the mounting plate would only add to your problems as the scope would attempt to spin like a record on whatever surface you placed it. Of course without the feet, it may scratch furniture if you are not careful, but for astronomical viewing, it makes all the difference in the world. The first step in Supercharging the scopes that come in is to remove those darned feet! I hope this helps! ---------------------------------------- P.

From: email@example.com (Jerod B Chatterton) Thanks for the quick reply. What I was proposing was to attach the mounting plate to the base of the telescope to simplify the process of mounting the ETX-125 onto the #883 tripod. I feel this would simplify things because it's one less thing to hold on to when attaching the 125 to the tripod. The way it is now, you have to hold the scope with one hand, hold the plate to the bottom of the scope with the other hand while trying to line everything up with the head of the tripod. It seems like if the plate was already attached to the base of the tripod with Velcro, you could just take the scope out of the case with both hands and set it right on the tripod, no third arm necessary. And you could leave the little feet on there because they would still fit nicely in the cutouts on the mounting plate (provided that Meade put the little feet in the right place to begin with ;-)) That's what I was trying to propose. Thanks again! Jerod Chatterton Logan, UtahAnd:
From: firstname.lastname@example.org (Clay Sherrod) Yes Jerod...that would work fine. I am not sure if Velcro would last very long, but it might be worth a try. Whatever you do, don't attach anything permanent in case you need to get inside the base or plan on battery operation of course! Clay Sherrod
Subject: new etx 125 Sent: Sunday, December 30, 2001 10:35:44 From: email@example.com (john donovan) i recieved a new etx 125 for chrismas. one of the main reasons i chose this model was because of all the great information and tech support that is on your site. the main question i have is about the updated model with metal bearings on the fork arms. my scope does not have these, should i try to exchange my scope for the updated model or is it nothing to worry about?Mike here: You would probably have a difficult time trying to convince the dealer to swap. Sort of like convincing the car dealer to swap a 2001 for a 2002 model.
Subject: Vertical Lock Broke Sent: Saturday, December 29, 2001 9:47:52 From: firstname.lastname@example.org (Gene Salvatore) I just recently purchased a Meade 125ETX system on eBay. After using the vertical lock 3-4 times, it actually stripped and came loose. There were some plastic pieces that came out of the middle hole where the brass, knurled horizontal rod is inserted. Is there an easy fix to this or do I have to go back to the factory? Thanks much, Gene SalvatoreMike here: I suspect it had been overtighten. Contact Meade; they will likely send a replacement part, assuming it is as easy to replace as with the ETX-90EC (see my comments at the bottom of this page: http://www.weasner.com/etx/90ec_comments.html. Alternatively you could repair it yourself using the info on the Scopetronix tech tip page (etxtu.htm).
Subject: Incorrectly Placed rubber feet. Sent: Friday, December 28, 2001 3:47:06 From: email@example.com (Jake Andreou) Just to add. I purchased an ETX-125 in October which also had the feet in the wrong place. They were placed over the screw holes (probably to stop people opening up the scope) instead of in the correct locations marked on the base. When I removed the feet, I could not reapply them as the adhesive stayed where it was and I managed to rip one in half. If you are careful you can reuse the feet with double sided tape or with a drop of glue in the correct location. Luckily I had some spare feet from a switch box which were the perfect size. Or you could buy some from an electronics store. Jake Andreou (UK)Mike here: Meade apparently will send replacement pads.
Subject: New ETX 125 problems Sent: Wednesday, December 26, 2001 21:57:20 From: firstname.lastname@example.org ( Wayne Hale) Purchased a new ETX 125 at a local Discovery store. Found the following problems that I'm sure others will find also. Mounting feet on telescope base are incorrectly positioned making it impossible to use the tripod mounting plate in the manner it was designed. I checked three brand new scopes at the store and found all had exactly the same problem. I called the MEAD factory and spoke to one of the support techs who suggested just pulling the feet off and reposition onto the smooth circles molded into the base. Unfortunately the double sided adhesive pads do not lend themselves to being used more than once. The factory support person offered to send a new set of feet. After peeling the original feet off, I noticed that the feet had been installed so as to neatly cover the three phillips head screws that secure the base assembly. Perhaps a new assembly person thought they were doing a good thing in covering up the screw heads? On the first of three scopes I brought home, the front lens cover was so tight that I unscrewed the dark ring securing the front corrector plate. By holding the ring and applying steady pressure to the lens cover, it finally came loose. The Dec lock was also excessively tight and I was afraid I'd break something applying enough force to break it loose. The white foam inserts that hold the OTA assembly were extremely tight on the first unit. The little warning lable telling you which direction to move the OTA to remove these pieces should be much more prominent. From looking at the way the foam is cut, logic would dictate it comes out the opposite direction than it really does. The RA lock on all three units have very little motion between off and lock. Even in the unlocked position, it takes a fair amount of force to move the OTA in RA. The RA Motor easily moves the OTA even it it is in what you think should be the unlocked position. I returned the first unit to the store and exchanged it for a second unit. Unfortunately the second unit was in worse shape than the first. In additon to the mounting feet being in the wrong position, one of the six adjusting screws for the finder scope was bent at about a 30 degree angle. I did not attempt to straighten the screw. Since the screw is inside the mounting ring, someone must have accidentaly put their finder in the ring and bent the screw. The RA Lock was also what I thought to be excessivly tight. The focus knob was fairly tight and a JMI Motofocus motor had some problem in moving the focus assembly at slow speeds. I did not feel the optical performance of this scope was up to par either. The tripod mounting plate for scope two had numerous scratches indicating that it had been on a tripod. The store assured me that the box had been unopened and they considered it to be factory fresh. I suspect this second unit had been returned sometime in its life and then returned to stock without being closely inspected. One could hardly miss the bent finder adjustment screw. I returned this unit and tried for a third. I must comment that the staff at the store were very apologetic for my trouble and were very anxious to make me happy. I took the third unit out of the box in the store room of the store and inspected the unit for the problems seen in the first two. Here again, the mounting feet were installed in the wrong position. The focus knob on this unit was even tigher than on the first one, the JMI MotoFocus could not move this one at all. By this time I had read all of the postings on this site regarding various problems with the 125. I elected to keep the third unit but immediately contacted Clay Sherrod and made and appointment for his Supercharge service. I'm waiting for a report from Clay to see what kind of mechanical and optical problems this third unit may have. I'm sure more units will surface with the mounting feet incorrectly installed and hopefully by now someone at the factory has made sure they are installed correctly. How QA could miss this oversight is somewhat disturbing as the circles moled into the base are very easy to see. I'll post the results of Clay's inspection as soon as I receive it.And:
Forgot to mention that two of my three ETX-125's exhibitied a random slew in RA while using the Manual hand controller. I've seen several postings about this problem with the Autostar but mine would randomly respond to a movement in RA in one direction. After releasing the arrow key, the unit would pause then the RA motor would start again slewing the OTA back the opposite direction several degrees, certainly enough to be noticed. Units 1 and 3 do the same thing. I didn't even take the second unit out of the box when I noticed the damaged finder mounting screw and incorrectly installed base feet. I also experienced a great deal of difficulty in unplugging the Autostar from the base unit and the coil cord from the Autostar itself. I finally resorted to a thin bladed screwdriver to put a considerable amount of downward force inside the connector on top of the latching lever to get it to release. The connector on the cord looks ok, suspect there is a tolerance problem with the female socket itself.
Subject: 125 and rubber feet.--a response. Sent: Tuesday, December 25, 2001 15:02:55 From: email@example.com (dgriff) I too have this same configuration. My first 125 had large feet which fit into shallow recesses on the base. I replaced my 125 and the second did not have feet, only felt tabs covering the base screws. The up-side is that using the tripod and base mount means "Who cares about orientation. Just line up the holes and go!" There are no feet to align to the plate. I will contact Meade about my new ones and I'll put them on if I need to. Don Griffith
Subject: ETX125 rubber feet don't align with slots in mounting plate Sent: Sunday, December 23, 2001 18:56:48 From: firstname.lastname@example.org (Barry Speronello) I understand that the rubber feet on the base of my brand new ETX125EC should fit into the slots cut into the circular metal mounting plate (that came with the 883 tripod) when the scope is mounted on the tripod. Mine don't. I've tried every variation on the orientation of the plate (both inversion and rotation), and they don't align. When I mount the scope on the tripod with the plate, the rubber feet are pressed against the plate instead of fitting into the slots. So instead of the scope base resting solidly against the plate, the scope is free to wiggle as the rubber feet flex. I can reduce the amount of flex by tightening the mounting screws and compressing the rubber feet. My concern is that with all the stress concentrated through the feet instead of being spread across the full flat face of the base, I may crack the plastic of the base near the feet if I tighten the screws too tightly. So in addition to the recognized instability of the '125/883 combination, I have the added problem of a flexing mount. I think the rubber feet are located in the wrong places on my scope. There are circular depressions molded into the base that are the same size as the feet, and they line up just fine with the slots in the metal mounting plate. I think the rubber feet should have been located in those depressions. Instead, one foot is located directly behind the south mounting screw hole in the base, and the other two feet are mounted 120 degrees offet from there. My dealer told me that the location of the feet on my scope is normal and that there's nothing that should be done unless I take it on myself to reposition the feet. But then I might damage the base when I connect it to the tripod. Or I might damage the feet removing them. Or the adhesive might not hold after it was repositioned. So I am reluctant to take matters into my own hands. Please advise? Is this arrangement normal and proper? Would you operate it this way if the scope were yours? Are my only options to either do it myself or return the brand new telescope cross country to Mead and wait a month to get it back? Thanks in advance for your help, and I apologize if this issue is already addressed on your great web site. I spent a solid couple of hours looking through the site and archives before bothering you with this question. Learned lots, but didn't find the answer I needed.Mike here: This is the second report like this that I've received this month. The first person contacted Meade and they sent a replacement set of feet.
Subject: Re: 125 fork index marks Sent: Sunday, December 23, 2001 0:44:04 From: email@example.com (Clay Sherrod) Hello Don - You are absolutely correct in this. I have found two additional ETX 125's that both have the right fork arm index as well....so apparently they have some out there (depending on date made??) with the index on the "fake" setting circle and some without. I am notifying Mike Weasner of this as for the present time, I think we can expect to see others with the index mark, but WITH the new mountings. You are also correct in that removing the setting circle and clamping knob WILL reveal a new metal trunion extension and bearing clearly visible immediately upon removal; this steel will NOT be seen in older models. Clay Sherrod ---------------------------------------- P. Clay Sherrod - firstname.lastname@example.org Arkansas Sky Observatory www.arksky.org ----- Original Message ----- RE: Your article on the newer production ETX-125EC's having only one index mark. Just checked my 125EC forks for the index mark for the setting circle and its naked twin. Both arms have the index, but removing the dec clamp and the setting circle clamp reveal metal bearings. Are there other bearings to which you refer that are hidden farther to the inside of the axle and outer bearings? Perhaps there was an intermediate production run where both arm and bearing conditions existed at the same time. JPG image of my forks available if there is a question. Any other changes made on newer 125"s that I may look for on mine?? Sincerely, Don
Subject: ETX-125 Mechanicals vs. Serial Number Sent: Thursday, December 20, 2001 6:07:37 From: email@example.com (Clay Sherrod) All of the newly-fitted Meade 125's were produced AFTER September 10, 2001, and that date code is on the outer shipping box. However, there are some with new dates than that which still have the old configuration. Short of taking apart the fork arms to look for metal bearings (they are quite obvious), there is ONLY one way in which you can quickly spot a NEW ETX 125 over an older one. In order to accommodate the new bearings metal reinforcement, the 125 had to have new castings made for the fork arms. OLD models had a "setting circle indicator arrow" (pointer) on both fork arms, even the right one which was a "dummy" setting circle. NEW ETX 125s do NOT have the arrow pointing to the fake setting circle on the RIGHT fork arm, or the one with no actual numbers on it! If it has a pointer for the fake circle molded into the plastic...that is an OLD telescope! Clay --------------------------------------- P.

Subject: RE: RE: Meade EXT 125 Problems Sent: Friday, December 14, 2001 17:54:50 From: email@example.com (John Clendinneng) Hi Mike, I sent my EXT125 back for replacement. I received it today and it is also defective. The focus nob turns but does not focus. the rod does not move outward or inward (feels very loose), is this something I can fix or should I send this one back to. Regards, John Clendinneng Montreal, QuebecMike here: Sorry to hear this. Is the setscrew on the side of the focus knob tight enough to hold the knob securely on the shaft? Or does it feel like the focus shaft itself is disconnected from the moving mirror?
The set screw is firmly set, so I would have to say that it disconnected from the mirror.Mike here: not good. suggest returning it.
And this tip:
I had something else to add, I made a small 0 dollar modification to my deluxe 833 tripod that may reduce the vibration considerably. I removed the tripod head by removing the 12 screws that attach it to the struts and I then filled the struts up with sand just below the screw holes. I then remounted the tripod head and checked for sand leakage. There was none, I then filled the tripod legs with sand by removing the bolts that hold the feet on. The result is a tripod that weighs 25 pounds and one I think will absorb vibrations very well due to the fact that sand is very good at absorbing vibrations. I have not had a chance to try my tripod as yet due to my earlier reported problem but I will provide you with the results when I receive a telescope that works. Regards, John Clendinneng Montreal, Quebec P.S. I got this idea from a friend who filled the legs of his patio table with sand to stop it from blowing away on windy days.
Subject: ETX Battery Power Failure Question Sent: Thursday, December 13, 2001 15:21:31 From: MCB1@aol.com I've got an ETX125 trouble shooting question that perhaps you might have information on, or if you could steer me to someone who might. I called Meade, and as usual they were very pleasant, but they weren't able to actually help me. They suggested bringing the telescope in for service, which means it would be out of service for 3 to 4 weeks judging by past experience. Apparently Meade's service capability for the ETX125 is in Mexico, where the scopes are built. The internal AA battery power for my ETX has died. The telescope still works fine with an external battery or the AC adapter, using the 12Volt input jack. However, when I use only the AA batteries and put the slide switch in the "On" position the red LED on the telescope's control panel does not come on and the AutoStar does not get any power. Do you know of other people who might have had this problem? I checked all the usual things - batteries, loose connections inside the telescope base, etc. The voltage is getting from the AA batteries to the slide switch, and through the slide switch, but the ground signal (the black wire from the internal AA battery compartment) is not making a complete circuit with the positive voltage (the red wire.) The problem is on the small circuit board (Meade part number 15-6305-00 Rev B) that attaches to the connectors on the control panel. Only one side of this circuit board is visible and accessible, and I can't see if there are any active components on the other side. I used a digital meter to check out the connections, and I can see that the problem is that the ground from the internal AA battery compartment isn't completing the circuit. I was wondering if you might suggest where I might get a schematic, or if there is someone in Southern California who can service the ETX125. Thanks for any help you might offer with this. Mike BertinAnd from our resident hardware expert:
From: firstname.lastname@example.org (Clay Sherrod) Short of taking it upon yourself to rebuild the circuit board there is little that can be done, except send the scope in to Meade. You cannot buy just the control panel circuit board as Meade will not sell them, even if you are highly competent enough to replace yourself. There are a bunch of "bad" control boards out there right now, but this is the first I have heard of this symptom....I trust when going back to battery power you ARE remembering to remove the AC power plug from the jack on the front of the control panel? Leaving in would give you the SAME results you are seeing. In addition, I would highly suggest that you take a toothpick and probe the tension-spring contact that engages with the AC plug when in use; many times that will become stuck in a position as to deactivate the circuitry through the battery, even with the plug removed as it should be. Normally I keep spare control panel circuit boards and others, but the demand for the control panel board has eaten my supply away completely and I am likely not to get anymore for some time. I would certainly suggest you check the adapter contact spring to make sure it is not stuck in the default position for the AC plug to be inserted....happens all the time. P.

Subject: ETX 125 EC Sent: Monday, December 10, 2001 13:31:45 From: Don.Spain@iccnet.com (Spain, Don (InPeake)) Got this scope at a bankruptcy sale for $100. It was a demo unit and was marked as the right and left drive did not work. I bought it for the OTA and mounted in on a German equatorial mount. Optically it is great. The large central obstruction is a minor drawback and planetary detail is a little less shape than I would like, but the Cassini division in Saturn's rings is easy, the double double is difficult but fairly easy under good seeing conditions. The moon (my favorite object) is fantastic. I live in a suburban location so deep sky observing is pretty much out, but saw many M objects this fall and even under the poor conditions they are easy objects. I checked the mount later and found a piece of plastic in a gear. After removal the drive worked just find. (I will say that the gears are not the best quality, they are plastic and the overall construction leaves something to be desired.) In any case I put the telescope back on the fork mount and tried it out. With accurate polar alinement it worked fine. Even with a 4mm eyepiece the star or planet held steady in the field of view for several minutes. It took only very minor tweeking with the hand controller to bring it back into the center of the field of view. I don't have the autostar and the little 6X23 finder is not much to work with. However, saying that, I did locate Uranus and Neptune in it and in the main telescope Uranus was a pale green disk almost 4 seconds across. Neptune was seen as a small blue disk, about 2 seconds across at 475X. I made a wedge of plywood for my latitude and now mount the scope on it. The space inside the wedge is great for eyepieces, books, maps, flashlight. If you like I could send a picture of this homemade wedge. It works great. I set the wedge on an small table outside and have had no problems with vibrations. Overall the opticals of the scope are fine. I wish Meade had used better components in the mount though. I love the 40 hours I get out of the 10 double AA batteries it takes to run this scope. If you like a relatively lightweight scope, easy to set up and observe, this scope will serve you well.

Subject: Meade EXT 125 Problems Sent: Sunday, December 9, 2001 17:12:21 From: firstname.lastname@example.org (John Clendinneng) Great web page. I was hoping you could help me out with a couple of issues that I have encountered with my EXT. I recently purchased a Meade EXT 125 telescope with the autostar controller and deluxe field tripod 883 and have experience certain problems at least I think they are. 1) The R.A lock does not seem to do anything. What I mean by that, is that when the lock is in the off position (to the right from the rear of the telescope) it still feels locked. I also performed a test with the lock in the off position using the hand controller, I slewed the telescope horizontally and held the telescope back with my finger. The telescope motor started forcing. Am I correct in assuming that the motor should not be engaged in the off position. 2) I set up my telescope in my back yard on the grass using the 883 field tripod and plate assembly. (the rubber feet on the base of the scope were removed and all controls on the tripod were firmly tightened) Using the standard hand controller I put Saturn into view. So my question is this, when using the standard 26mm eyepiece (73X)is it normal to get a jiggle when attempting to focus. No matter how lightly I touch the focus knob it jiggled making fine tuning difficult, is this normal? I was expecting jiggles at 200X plus but not at 73X. In closing I am not to pleased with this telescope I was expecting more. The autostar works just fine, every object appears pretty much centered in the scope. Other issue I've had with this scope, the 825 right angle finder was defective, its being replaced as we speak and the icing on the cake there was a rattling sound in the base I noticed when putting the telescope away after it's second use. I managed to remove a piece of blue plastic and a 5mm machine screw from the inside of the base. I accomplished this by removing the batteries and inverting the scope about 15 times. I have had this telescope for 7 Days now and I have a choice to make get the ext125 replaced or get a Celestar8 my final decision will rest on the focus knob issue. I love the Autostar system but I don't feel I can live with such an unstable telescope. I am Just the recipient of a lemon, any feedback would be Greatly Appreciated Regards John Clendinneng Montreal, Quebec Canada 1-514-425-0427Mike here: The RA lock should unlock the axis allowing you to move the telescope by hand. Similarly, the drive should not be attempting to move the scope in RA (Azimuth). Can you move the lever to full-lock position? (Don't overtighten however.) As to the vibration you see, yes, that can occur, especially if you extend the #883 legs to their full height (I keep mine totally unextended). Using a focus knob aid (like the oft-recommended clothes pin, one of the flexible focus cables, or an electric focuser) can reduce vibrations considerably. Also, the surface you place the tripod on can affect vibration dampening (soft is better than hard). Adding weight to the tripod also helps.
In answer to your questions regarding my problems. The R.A lock will only move half way to full lock position, as for the tripod, the legs were totally unextended and placed on the lawn when I performed my test. I did another test with the tripod that I failed to mention. I taped the tripod and observed the vibration that was caused. The result I deemed acceptable but when I tapped the telescope it created a much larger and pronounced vibration. Thank you very much for the info I'll try a close pin Tomorrow evening and let you know. Your help is Greatly appreciatedMike here: Regarding the lock lever, you can put it into the full lock position and then loosen its setscrew and reposition it the lever more to the fully locked side. That should allow you to more completely UNLOCK the lock.
Subject: ETX 125 Rear Port Loose Cap Problem Sent: Friday, December 7, 2001 8:35:35 From: email@example.com (Kevin Berg) For anyone affected by the loose cap on the rear port and the consideration of glueing it in place using locktite, you may want to think again. I would strongly take Clay's advice and just leave it alone. Why? Because even though you may never use a camera, remember that the nifty 45 degree erecting prism also uses that port for some awesome terrestrial observations, if you are ever so inclined. Kevin
Subject: ETX 125 Sent: Wednesday, December 5, 2001 21:18:09 From: RotunnoRon@aol.com I've had my ETX 125 for about 6 months (it seems to work fine based on my skill level) but I do have one question. At the rear of the tube where the cap goes for where you would attach the camera adapter, I noticed that the fitting that the cap goes onto (between the cap and the tube itself) does not tighten into the tube. while its not really loose, it's not really tight either. Do I have a problem or is this just something I never noticed before? Best Regards, Ron RMike here: Well, guessing here, I would suspect that some sleeve on the inside is loose. Here's a response from our resident hardware expert Clay Sherrod.
From: firstname.lastname@example.org (Clay Sherrod) I am seeing an awful lot of these lately....a bunch. I would suggest that if the user is NOT going to be using a camera off the end of it to leave it alone. Unfortunately there is no sleeve nor jam nut on the other side of this unit....it merely self-threads into the read housing of the scope and if loose there is only one way to tighten, short of sending the scope back for replacement or repair....GLUE. Red Locktite (not any other color) will take care of it, BUT, I do not recommending repairing unless the scope is out of warranty or if the person actually needs to use that rear port. All one must do is to carefully apply very sparingly, several drops that are allowed to penetrate into the tiny seam made by the internal (threaded) fitting) against the plastic OTA back. This red Locktite will get in there and seal those threads and take that problem away. You MUST be very careful to no get the Locktite on the external threads and for this reason I do not recommend this unless necessary; also never use so much of this that it can actually penetrate so deep that the liquid will come out the other side. One drop is all it takes, and I always apply about every 30 degrees around the unit until completely done around the circle. It is not that difficult to do.....but if you are not going to use the port, I would say "just stay away from it!" Clay Sherrod P.

Subject: Greeting from Bratislava, Slovakia Sent: Tuesday, December 4, 2001 11:12:28 From: firstname.lastname@example.org (Kvetoslav F. Zavodsky) Dear Mr. Weasner! (Excuse me, if you find in Your name some mish-mash). 1./ I dont know, where are you staying, but if we can speaking German, itll be a little easier for me. Please let me know, where are you staying. My place Bratislava is 80 km from Vienna. 2./ As I allready wrote you, my experiences with the MEADE ETX 125 EC with AutoStar are limited for the first month only, but with the MEADE LX 10 and ETX 90 RA I was working for the late two Years. In comparison with LX 10, the ETX 125 EC is so far to mechanical construction of ETX 125 EC - very weak, almost as a toy for children. I have a problem to tight the RA and DEC for a practical use with the AutoStar: The tubus of the ETX is "falling on the nose" although the DEC screw is very tight. The same problem with the RA: The Autostar, after a few moves from East side to another object on the West side - cannot find again the object, which was found as a first object. The ETX 90 RA has much better holding in both axes. I wonder, why the producer MEADE (in other way very good telescope) had for the ETX 125 EC made worse mechanical construction as for the ETX 90 RA. 3./ I have adapted a WEB camera to this telescope and Im surprised with the quality of the moon-photos. Thanks for your informaions, Ing. F. Zavodsky, BratislavaMike here: Certainly there were compromises made to the ETX line to get it within the price range for the intended market. That market is different than the one for the LX models. I suspect many of the problems you are experiencing can be fixed by either returning it to the dealer for a warranty exchange, or if out of warranty, by doing the appropriate tuneups mentioned on the Telescope Tech Tips page. Please note that not all ETX-125EC models require tuneups although doing it can make it perform better, should the user desire that. As to my German, I am several decades out of practice!
Thanks for your advices Mr. Weasner ! 1./ My ETX 125EC is is a new one and it is indeed in Warranty yet, but MEADE limited Warranty is no help for the customer in my case: My delivery and service place is 900 km away from me (in other state - Germany) and MEADE Europe is that opinion, that I am ought to sent it per post (perheps for a month) for Warranty service. They are not ready to change it for a new one. Thanks for such a warranty! I am not ready to let it for a month in other country, because of that time I have no scope and no money too... As you see, I must find out my own help for my problems in your "Mighty ETX 125EC site". Perhaps I find there some good advice how can I better brake the RA and DEC too. 2./ I sent you a picture of my telescope polar/alt.-az.mount (speciall made alike the MEADE LX 10). Because of my not the best experiences on the sky object identifikation I mounted on the tubus of the ETX a gun-wiever, which let me see the place around the searching object in life-really position. Thanks - Ing. F. Zavodsky, Bratislava
Subject: Greeting Sent: Monday, December 3, 2001 10:33:31 From: email@example.com (Kvetoslav F. Zavodsky) Im a newcommer to MEADE ETX 125EC together with AutoStar and SW Starry Night. I hade before the MEADE LX 10 an the ETX 90 RA too, and I see a few problems with a brake of the RA and DEC stability. What can I do with the free state of that? Please, help me if you know: ng.

Subject: ETX 125 Vertical Axis Sent: Sunday, December 2, 2001 16:47:11 From: firstname.lastname@example.org (Jaidev) Hi, I have a ETX125 which is about 3 months old, recently I have noticed when using the scope and it is targeting a object, sometimes when it lews up (the vertical axis) the tube stops moving, but the motors keep whirring, like its trying to still slew up but cant?? This also happens when Im manually, trying it with the autostar hand controller. Cheers, __________________________________________ Jaidev PatelMike here: Try this: loosen the Altitude (Declination) lock and manually move the OTA from horizontal to vertical and back to horizontal. Do this several times. Then lock the axis and try to slew the OTA in Altitude using the handcontroller. Let me know if this helps.
