Question about Galileo 90mm Reflector Telescope with Multiple Ocular Holder

1 Answer

My declination adjuster works one way but not the other.

It turns the adjuster screw but not the telescope. I thought maybe the nut that sits at the top of the mechanism just needed to be tightened but all that did was make it so it didn't turn at all. Any help is appreciated.

You must loosen the nut 1/2 way so you have travel distance in BOTH direction.

This is only for small movements. For larger direction movement you must loosen the adjuster and manually move the scope.

I just bought a beater truck. 88 gmc Sierra. Vortec v6. It is idling really high. When u put in gear, it jumps. Maybe they did it to prevent stalling. Two questions. 1. Why would it be stalling? 2. Where...

Is it carbureted or fuel injected? There might be a screw by where the throttle cable attaches to the carb that adjusts where the throttle plate sits at idle. Or the timing could be too far advanced. You can adjust that by loosening the nut under the distributer and turn it slowly with the engine running. Counter clockwise.

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:

also this web site

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!

How to clean my Galileo telescope

Good luck with the nuts! Maybe try light adhesive to attach nuts and carefully screw in.
Use only distilled water! Rinse with distilled water. For stubborn spots, add 1 drop of dish detergent to 1 qt of distilled water. Soak a cotton ball and gently swipe ONCE across spot. Discard cotton ball and use a new one until spot gone. Rinse with distilled water and set on side to dry.

I am trying to change a headlight. I can't can not

The headlight assembly (1993 Grand Caravan) is held in place with three plastic "wing nuts" that rotate on the ball-end (front end) of the adjusting screws. One "adjusting screw" (the one on the bottom, inboard side) is not for adjusting, just for mounting. The other two adjusting screws take a torx T15 in the front end of the screw.
Removing the headlight assembly is somewhat of a trick - it seems like it takes a special tool to reach the "wing nut" and turm it 1/4 turn (90 degrees) CLOCKWISE (so the "wings" are vertical). When all three of these mounting "wing nuts" have the wings vertical, the headlight assembly just pulls forward and off these mounting nuts. Place the new assembly back over the "nuts", turn the 3 "wing nuts" another quarter turn, and the new unit is mounted. Probably not even a need to re-adjust the headlights, but you should check.
The PROBLEM, is that it appears to take a special tool to reach and turn these wing nuts without breaking them (yes, the old ones get brittle). I tried a socket (did not work), and then long needle-nose pliers (broke one wing nut), then a 1/2" open-end wrench (which at least worked). However, pushing the new assembly back over the wing nuts, I broke another wing nut. So, I broke 2 of the 6, and one was broken when I started.
Now I need to find replacements for these "wing nuts" ... any ideas where to get them?
Of course I can use some washers, some nuts to fit the fine-threaded adjustment screw, and some sort of bushing (maybe cut a short piece of rubber tubing to fit over the adjustment screw). Place double nuts (second nut to lock the first in place) and a washer, then the bushing onto the adjusting screw, then the headlamp assembly onto the bushing, then add another washer, and two more nuts (not too tight) to lock it onto the adjusting screw (which must still be free to rotate). Repeat for each of the 6 mounting points. I have not tried this yet, but ... it should work.

Fabricate a tool to turn the "wing nuts" using a piece of 3/8 inch ID tubing which you file or cut 1/8 inch by 1/8 inch notches on each side of a diameter line.

Hello I have a 2001 harley road king . When sitting still and trying to put in 1st gear . I am getting a slight grinding sound . And the bike is hard to go in gear . Do you have a solution or do i need to...

A slight grinding noise is common when sitting idling with the clutch out and then trying to put the transmission is first gear, especially when the transmission is cold. You can try holding the clutch in for a short while and then try putting it into gear to see if that stops it. I'm not sure adjusting the clutch is going to help much. It's a matter of stuff spinning and other stuff not spinning in the transmission.

If you want to adjust the clutch, find the "bellows" type cover that covers the adjuster in the middle of the cable. Work this cover up or down and uncover the cable adjuster. Break the lock nut loose and adjust the adjuster inward making the cable shorter. Adjust it all the way in.

Remove the derby cover. You may want to stand the bike up fairly straight up to do this to make sure you don't have any oil running out of the primary. With the derby cover off, you'll see the clutch pressure plate. In the middle of the plate, you'll see a screw with a lock nut on it. Make sure the bike is in neutral. Break the locknut loose. The engine may try to turn a bit when you try to break the nut loose. Turn the screw inward until you feel a resistance. I usually do this then back the screw back out a bit and then back in several times to make sure I'm at the point of resistance, no further. You don't want to start releasing the clutch with the screw. Once you've turned the screw inward until you feel the resistance, back it back out 1/2 to 1 turn. Lock the lock nut back down and reinstall the derby cover.

Then, adjust the cable adjuster out until you have about an 1/8 inch of free travel at your clutch lever pivot. I usually use a nickel between the clutch lever and the lever stancion.

Locking screw

You will need to check out the clutch mechanism in the fork arm. Refer to this web site for disassembly pictures.

Look under Declination adjustment link off the main page.
sells an upgrade clutch kit that improves the clutch. However if something is broken inside then this must be fixed first. Meade will want the scope returned. They usually do not sell parts; but sometimes they do sell them, so call Customer Service here:
