You have GOOD power? You can try and replace the hand controller cable--

I would also Calibrate motors, and retrain the drives. But re-training must be done in alt az mode.

Tip

You Just Bought an EQUATORIAL Telescope Mount!


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

also this web site

http://www.telescopes.com/telescopes/polaralignmentarticle.cfm

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.

Hope that helps you!

Clear Skies!

I have 2006 harley FLH CVO WITH NEW TRUE DUAL EXHAUST AND POWER COMMANDER THAT HAS A BAD VIBRATION AT IDOL


the only thing spinning and vibrating at idle is the crankshaft, gear box , clutch and flywheel
if the power commander is electronic there may be a fault in it
best place for these faults is a dealer shop as they are aware of these sorts of problems

Manual for TwinStar 1000mm focal length telescope and equatorial mount


Equatorial mounts need to be polar aligned to work correctly. Once the scope is polar aligned (see manual or look online for polar alignment instructions), turn on the RA motor. Loosen your RA and DEC locks and find a object you want to view, The motor should keep the object in view for a while (depends on how good the motor tracks and how good your polar alignment is.) Spending 10 minutes polar alignment on my C8 keeps the object in view for about an hour without adjustment.

I have a C8-SGT (XLT) Computerized Telescope, just brought it out first time this year. It is not tracking after I slew to an object. I've checked and rechecked the hand control settings. Any...


Hi,
I assume you mean you have set tracking on by:
Setup key, scroll to Set Tracking, select Sidereal Rate, press Enter

This should get tracking going for celestial objects.

Another possibility, if the mount is not tracking well, is that polar alignment is not very precise. This will immediately show up when doing a 3-star alignment.

I have never had a telecope before and have purchased the Celestron 114EQ modelr n 31042 Im looking for step by step instructions on how to use it


Do you have a manual?

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.

Read this:
http://www.astronomy.net/articles/4/polaralign.html

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 cannot adjust the telescope in order to see celestial objects other than the moon. I may hve altered the focus point can you help? I have never really been able to use it and have had it for years now,...


You need to learn the night sky. Join a local astronomy club and the members will help you.

If your scope is on an equatorial mount. The mount must first be polar aligned in order to use it.

What would be the prefered age group for the 784501 bushnell telescope,.......in other words,,is it a kiddie telescope, or good for 30 yr old?


This is a 4.5 inch REFLECTOR on a shaky Equatorial mount. The mount must be polar aligned on the star Polaris in order to be used.

We usually recommend the telescope shown below for beginners of all ages--

for kids the 4.5 inch

for adults the 6- 8 inch version

This scope does NOT need to be polar aligned --

Here is the manual:
http://www.celestron.com/c3/images/files/downloads/1228334587_nexstargt.pdf

This is an ALT AZ goto scope. Read the manual above. You use the hand controller to move the scope in Altitude and Azimuth(left-right).

You must align it on 2 stars in order for it to has successful gotos.

Read the manual above.

How do i set up a tasco telescope


Here is the manual:
http://www.tasco.com/products/manuals/46060675_TML-722.pdf

This is a very small refractor on an equatorial mount. The mount must be POLAR aligned before you can use it. We NEVER recommend this to a beginner.

However you bought one anyway! SO--- go to my profile page and read my TIPS on polar aligning an EQ mount. Several of the other TIPS will help you.
