GoTo Problem Please Help... im and going crazy!!! I have a Celestron Nextstar SLT 130 GoTo scope and love the pictures it produces but cant get it to GoTo very well. It dose the three star alignment, 1 star alignment and solar alignment fine and have no problems with alignment, level the scope well and set the time to nearly the second. Once aligned and i start to move the scope around the night sky, if i try to ask the socpe to slew back to a star, even an alignment satr, it goes in the general direction but doesn't bring the star into the view field and is off by a significant amount. I have tried centering the star in the view and then asking the scope to find that star and it goes out of the view by the same amount every time. Im goging crazy. I thought it was a motor problem and swaped the scope at the store but the new one is exactly the same. I just dont know what is wrong. Im in the southern skies and only reviews is for the northern, dont know if this matters. Any help would be fantastic. Just cant get it to slew to any objests correctly!

Be sure that the telescope is configured for EQ SOUTH mode to tell it is in the southern hemisphere. Once a star alignment is completed NEVER manually move the telescope. Use only the control panel to slew. Everytime the telescope is move by hand, the motors do not know it has been done, and assume it is still pointing at the old direction. Check the manual for setup.Here: http://www.celestron.com/c3/images/files/downloads/NexStar_SLT_manual.pdf

Scope is 12.5, 9 years old. We align by going to "named star," selecting one, slewing, correcting, hitting synch. Repeating with another star. Almost always the scope goes to accurately there after. (We avoid the "align" menu which we never got to work). Now, after we align first star, scope turns erratically in circle instead of slewing to second, as if it didn't want to cross the meridian. We tried turning it off starting again, nothing works. Eventually stalls.


Runaway DECLINATION is what this is called. Usually it can be fixed with a new hand controller cable. If a new cable does not fix it, then it has a blown motor circuit board and must be returned to Meade for repairs.Meade customer service:http://www.meade.com/support/index.html

Aligning my scope and slewing problems


You need to synchronize the telescope with stellarium. Center the telescope on a known star, then select the same star on the laptiop and 'synch' with it.

I have an lxd 75 goto mount. When I align on a star the ra motor skews to infinity and registers a motor fault. It skews just fine from the hand controller but when I try to align during setup it goes crazy. Any suggestions?076420h 40


Most probably has a faulty shaft encoder on the ra motor. If the encoder is working correctly the fault will lye in the H-Bridge circuit that drives the motor or if you're really unlucky, further up the signal path from the detectors

Problem with Celestron Starseeker 100mm refractor


Could be several different mechanical or electronic issues with the scope. From a dirty encoder disk inside to a bad motor clutch.Best to return it to Celestron for repair.

Problem with alignment of Meade LX90 8" telescope


Start from scratch- RESET the hand controller.Calibrate motors using the same power source you will use outside.Re-train the drivesCalibrate sensors on PolarisUse either the 110 volt power cord, or buy a 12 volt power pack and the proper Meade 12 volt cable. (www.scopestuff.com carries the right 12 volt cable)If your scope is NOT the LNT or GPS model you must level the tripod before you align. Go to home depot and buy the $3 small plastic two way bubble level, or the bulls-eye style bubble level.Further trouble, I suggest going to the LX90 Yahoo group forum, and asking questions there.Good Luck

Meade LX200GPS The scope does not complete the 'Auto Alignment'


Once the scope has taken a GPS fix and knows TIME, and SITE, and you do a two star alignment your alignment stars overide any automatic alignment issues. You could turn off the GPS put in Time, Date, and Site, do a two star alignment and everything would be fine. Centering the alignment stars is the "trick". Apparently the scope also finds NORTH OK, or the alignment stars would be way off. Since you pre-level the tripod already the software can FAIL on "tilt" and you still get good gotos.I would not worry about it, especially since your gotos seem perfectly fine.

Auto Align??? DS-2114ATS-TC


The alignment stars will be nearby BUT MAY NOT BE in the eyepiece-- you must center the alignment stars using the hand controller-- after you center the second star the GOTOs should be OK.

GOTO ERRORS MEADE LX200 10" CLASSIC


Most problems tend to be mechanical. Have you 'trained' the drive and set the backlash values? Those 2 can have dramatic effects on pointing accuracy. Also, if the optical tube is not in alignment with the mount, then nothing will work correctly. To check that, have the telescope in Alt-Az configuration, inside the house, loosen the RA lock, and shine a laser pointer on the corrector plate. as the telescope is rotated about the RA, the reflected spot should be steady. Adjust the DEC to minimize the diameter of the circle that is drawn. What is left, is the out-of-true on the DEC axis. That can be adjusted with the tube cradle alignment bolts.

Having a clear sky last night i took my new scope out and started to view the night sky, but focusing on a star ! i found that when viewing it at magnification a could clearly see the the area infront of the scope the supports the viewing prism/mirrow and the cross braces that support it, am i trying to view a subject that is "too far" i am VERY new to all this and i am using a celestron 114EQ scope from new any help appreciated Ray


Stars are ALWAYS pinpoints of light when the scope is focused no matter how much magnification is applied.You are NOT focused properly -- when you are you cannot see the secondary mirror or the "spider" bracket that holds the mirror.You will NEVER see a star as a disk, only as a pinpoint light. If you are seeing what looks like a donut with a dark center you are not focused.
