Aligns to three known stars ok but then why does it go to completely wrong area and slews in slow speed?

Ha, a familiar problem with Synscan and similar. You must do these things exactly right. Set up the hand controller properly for
- time (daylight saving or not)
- location, lat and long.
- hemisphere N or S

The mount must be
-levelled (don't trust the bubble on the mount, they are rubbish)
-pointed at the celestial pole (if an EQ mount)
-pointed due S or N (if alt-az)

You will find that most of the time a 2-star alignment is sufficient. Attempting a 3-star alignment is usually only successful if you have also taught the controller about geometry errors in the mount itself (they all have such errors), which is a tedious procedure you ought to leave until later. Even a 1-star alignment may be enough for planetary and lunar obs.

Don't neglect to use the "sync to object" feature it probably has in the hand controller. To use this you slew to an object using a medium to low power EP, activate the sync feature, center the object in the EP, and press enter. This has the effect of fine tuning the pointing accuracy in that segment of the sky.

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!

Cannot see anything thru telescope even daytime

  1. Get Stellarium or another fine astronomy program
  2. During the day, point the telescope at a part of the landscape about 100 yards away.
  3. Use the lowest power eyepiece (highest number) in the focal tube.
  4. Center the landscape object in the telescope.
  5. Align the finder scope so that it points exactly where the main telescope is.
  6. At night, leave the scope out to reach thermal equilibrium (about an hour for small reflectors and refractors)
  7. If the scope is on a EQ mount, polar align.
  8. Point the finder at the moon. The moon should be in the main scope also.
  9. Practice finding the moon before you start on the planets
  10. Once you are comfortable with the moon and planets, you can go for the deep sky objects

How do I set up my go-to telescope

A "Go To" telescope needs a couple of things to work. First, it needs to be pretty level on the tripod or mount. Set the scope up in an area where you will be able to see a large portion of the sky without obstructions as you will need to align it using well-known sky objects at widely separated portions of the sky.

Follow the align procedure in the manual and enter the time, date and location. Then using either two-star align or solar system align, let the scope come close and then fine-tune it onto the objects you're aligning with. Until you either move the scope or power it off, it should continue to track from that point. Of course, you need to be able to visually find the alignment objects yourself first... Go-to is sort of a misnomer in this case - you have to find them first during the alignment and then the scope will continue along on its own.

I was given a telescope and rolled one knob upward to look at sky and rolled other knob into position. Everything went black, so I rolled them back down. Still black. What did I do wrong?

You need to do two things before you take it out at night.

1. Align the small finder scope with the main tube. During the day time focus on a distant object like the top of a telephone pole. Without moving the main tube-- adjust the finder scope so the crosshairs point at the exact same spot.

2. Practice focusing during the daytime on distant objects.

Objects in the night sky are tiny-- smaller than the tip of your finger held at arm's length. The scope must be pointed directly at them,. Download a free monthly star chart at:

I just purchased a B.L model 4000 telescope. I do not have the owners manual. It has the feature that allows you to program the unit so it stayes on a object by compansating the earths rotation. How do...

You will not find a manual. This scope has been out of production for several DECADES!

The small wedge must be polar aligned in order to track the sky. The legs must be adjusted for your latitude.

It has a motor inside that rotates the scope to compensate for the motion of the sky once the scope is polar aligned.

Lost my manual

You have a 60mm refractor telescope on an equatorial mount. First the mount must be polar aligned in order to useit. Second I believe these take .965 eyepieces. Most amateur scopes use 1.25 inch eyepieces,

The eyepieces are very cheaply made. Some may also have plastic lens instead of high quality glass, and they are not muti-coated lenses.

Why am I saying all this? because this scope will frustrate you. The tripod is shaky and the connection between the mount and the scope tube is never solid. The scope will not stay pointed and it will be difficult to move it around the sky accurately. Sky objects are very tiny. Less than the tip of you finger held at arms length!

We never recommend an EQ mount to a beginner, and never recommend a 60mm telescope. You could have bought a pair of 10x50mm binoculars and they would have been much better for astronomy.

The manual will NOT teach you how to polar align the scope or how to find objects in the sky.

Read my TIPS on my profile page Frequently Asked Questions, and also the one on aligning an equatorial mount on the star Polaris.

This is the only manual I have ever found-- someone took images of the manual and posted it on-line-

I can go through the Sky Align procedure and the telescope will not find an object for which it has been tasked (ie. the Moon). I have triple checked the time, lat/long, etc. and still no luck after many...

Is the mount level? Did you center both alignment stars?

Are you running it off of fresh batteries or an outside power pack? 10 degrees sounds like Daylight Savings time is set to YES instead of Standard Time.

Alignment problems

I'm not sure of which telescope and finder you have but I can give you some general instructions.

If your finder scope is is the type that is like a tiny telescope then you should see a set of cross hairs when you look into it. The goal is so that when the object is in the center of the cross hairs you should be able to find it in your telescope eyepiece.. To do this you need to align the finder scope,

I usually use a terrestrial object to do this. I use these because they don't move like stars do. You can choose road sign, a spot on a tree or a street light though that can disturb your night vision. Aim your finder at this object and center it in the finder. Check to see if it is in the eyepiece of your telescope. Use a low power eyepiece to give you a wider field. The low power eyepieces have higher numbers such as 25mm. If the object is not in your eyepiece find it and center it. Check your finder again. You need to adjust the finder so that the object is in the center of the cross hairs.

There are usually 1 to 3 thumb screws to adjust this. If there a three you go back and forth until it is centered. Check your eyepiece again to make sure the scope is still centered. You can use a higher power eyepiece (lower number) to refine this since it displays a narrower field. Just repeat the process.

Once this is done, you find the object in the sky in your finder and center it and it should be there in your eyepiece.

Clear skies!

Start Align with NexStar 4SE

Did you enter the correct TIME, DATE, and LOCATION? and yes you may have aligned on to the wrong stars -- they need to be "near" the center.
