Right ascesion slow motion control knob loose, does not work
Hi,
first time used my telescope in couple years, watching Jupiter, keeping in center with dec. slow motion knob and found RA ascension slow motion knob loose, just spinning, no movement from the scope what so ever , RA was not locked, tried in partially lock, no change.
When I manually turn scope, the knob will spin some, I'm not sure if the screw in the knob is just loose, but where to you get a tool to tighten it?
Any ideas??
thanks
Amy

Can't find a manual. This is a 76mm reflector on a Alt/AZ mount. 1. During the day, put in the 20mm eyepiece and point to a object around 100 yards away. 2. Focus on the object 3. Align the finder to the object in the eyepiece 4, Set up at night, give the scope time to reach outside temperature 5. Point scope with finder at the moon. (More than half full will be too bright) 6 Use the lowest power eyepiece (highest number) and focus on the moon. 7. You may now use higher power eyepieces to observe. 8. Pointing the scope usually involves loosing 2 knobs to move the scope in up/down and side to side motion. There may be slow motion controls to adjust the scope as objects in the sky move.
Even though we warned you not to do this, you bought one anyway! Beginners should never buy an EQ telescope mount as their first telescope. It's too late now; so I guess we will need to teach you how to use it!
Equatorial mounts move in a way that seems not to very intuitive. Unlike the easy Alt AZ mount which moves up and down and left and right, the EQ mounted telescope seems to move in TWO dissimilar directions at the same time.
Additionally you must first polar align the mount on the North star Polaris before you can use it. SEE! we told you not to buy it!
Here are the steps to roughly polar align the telescope so you can use it. If it is motorized the single Right Ascension motor will keep the sky object inside the eyepiece for long periods of time. If you do not have a Right Ascension motor, the slow motion RA knob can be slowly turned to keep the sky object centered in the eyepiece.
Begin by leveling the mount and tripod. Move the entire mount and tripod so it is pointing roughly to North, as close as possible using the steps below or a compass. Don't forget to adjust for your magnetic deviation. My location's compass reading is about 5 degrees away from true North. This is called magnetic deviation. You can find your location's deviation on the internet. Then proceed with the steps below.
First, adjust the Declination to the latitude for your observing site. Declination is the angle that the scope is pointing UP, and it's the same as your latitude. For example Dallas, Texas is about 32 degrees North latitude, adjust the scope so the small indicator reads 32 degrees. By the way, the North star in Dallas, TX is about 32 degrees above the horizon. Your latitude matches the elevation of Polaris (the North star) above the horizon.
Second, either look through the polar alignment scope buried in the axis of the telescope mount, or look along side the axis, and get the star Polaris lined up in the cross-hair of the polar alignment scope, or as best you can by looking along the side of the mount axis, or lining it up using your compass.. This will put the scope to within about 3/4 of 1 degree of the TRUE North celestial sphere. This is good enough for VISUAL observation, but NOT good enough to do astro-photography..
Adjust the DECLINATION up or down, and move the entire mount left or right until you can see Polaris as indicated above, or it is lined up as close as possible.
Now you are roughly polar aligned. Now you can move the tube around by loosening the Right Ascension lock, and or the Declination lock until your sky object appears in the small finder scope mounted on top of the main telescope tube.(DO NOT MOVE THE MOUNT, and the counter weight should never be higher than the telescope tube) Lock down the scope in both axis and use the fine adjustment RA and DEC knobs to center the target. Again, DO NOT move the mount or tripod. The mount should still be pointing at Polaris.
This web site illustrates this procedure: http://www.astronomy.net/articles/4/polaralign.html
You should be able to keep an object within the field of view of the eyepiece by slowing turning the Right Ascension slow motion control knob-------- IF you are actually accurately polar aligned. Small adjustments may also be needed with the DEC slow motion knob since you are not exactly polar aligned using this rough alignment technique.
However it can be used successfully for visual observation. Your scope will now track the motion of the stars as they move across the sky.
This is a small reflector style telescope on an equatorial mount-- the mount must be POLAR ALIGNED in orderr to be used properly. Guess you did not know that when you bought an EQUATORIAL mount.
Once the scope is polar aligned place the eyepiece with the largest number written on it into the focuser. The moon should be your first target at night. the RA knob and the DEC knobs (slow motion controls) are used to keep the object centered in the eyepiece.

I would be surprised if ToysRus told you to contact FixYa. This is an advice site largely manned by volunteers, with no connection to ToysRus or Edu-Science. I would suggest that you contact Edu-Science to get the missing CD, or insist that ToysRus refund for the defective (missing parts) item they have sold you.
Don't worry about Jupiter. It is not going to disappear. I have been watching it for decades and it is almost always up there.
In XP go to device manager and expand list of IDE ATA ATAPI controllers. Right click on primary IDE controller and select properties. In advanced screen check primary IDE mode - that should be DMA.
IF that is in PIO mode - that is your problem.
Just click on driver tab in the same window and click uninstall.
REstart computer twice and problem should be solved.
Please leave your feedback if issue is solved
You apparently broke the focus knob-- in that small telescope you will be lucky to ever get 100x--- use only the lower power eyepiece, or return it as you said.
Here is the telescope that I recommend to beginners-- they come in various sizes depending on how much you want to spend. BIGGER costs more.
I assume you are using the 497 hand controller? Planets will always be a little bit OFF since their orbits are calculated. You should be able to see Venus, Jupiter, and Saturn as a disk-- the other planets are very tiny and can be mistaken for a star.
Use the Automatic alignment feature and center the brightest nearest star. It will not be in the eyepiece. Be sure you calibrate motors, and train the drives, and the time, and date and site are accurate.
the middle dial on the right side of the watch is used to switch from watch settings to alarm settings..
pull the middle dial out to put it in alarm mode.
To set alarm:
-pull the center knob out.
-with it out you can now use the bottom (right) knob to set the alarm.
-pull the bottom right knob out one notch
-turn the knob clockwise or counter clockwise to set the alarm time
-push the knob back in (all the way)
the alarm is now set
if the center (right) knob is pulled out the alarm is ON
if the center (right) knob is pushed in the alarm is OFF

I have owned this watch for about 10 years now and love it.
the past few years the chronograph buttons (on the left side of the
watch) were not working well rendering the chronograph and count down
timer functions unusable.
repairing a chronographs is expensive and watch makers usually charge
several hundred dollars which is not a feasible fee for a watch of this
value so i decided to open it up my self and clean it up and that did
the trick.. its working like new!
Sorry telescope is a Meade LX200GPS
Thanks again for any help
Amy
looks like an allen wrench should work but the inside of the screw is round????
