20 Most Recent Celestron AstroMaster 114 AZ (50 x 114mm) Telescope Questions & Answers

A 10 mm. If you know the focal length of your scope, divide that by the focal length of the eyepiece, and the answer is the magnification you will get. However bear in mind when viewing astro objects, a very high magnification will degrade the image sharpness, and make the object hard to get on centre. Most experienced amateur astronomers use a medium power eyepiece at most.

Your DEC is the same as your Latitude--

Right Ascension does not matter for now. Polar Align the scope on the star Polaris-- read this:

Once you are polar aligned, rotate the tube to a star in the sky that you KNOW the name of. Look up the Right Ascension of that star on a cell phone app or a laptop planetarium program like this one:
www.stellarium.org

Rotate the RA setting circle so it matches what the phone or laptop indicate. LOCK down the RA circle. Your scope is now adjusted to the sky and you can use the numbers on the DEC and RA to find other objects of known RA & DEC.

No glasses would not matter. Practice focusing on a distant object during the day time. Locate a local Astronomy club, the members will help you.

Did you put an eyepiece into the focuser? You are NOT in focus -- practice focusing during the day time on a distant object. TURN the focusing knob to either the left or the right until you get a sharp image.

It depend on the eyepiece anywhere from 10-20mm away.

Put the eyepiece with the largest number written on it into the focuser. DO NOT use the 2x barlow -- practice focusing on a distant object during the day time.

RA moves the polar axis--- and DEC moves the scope from side to side.

There are two knobs that turn these two axis.

Put the eyepiece with the LARGEST number written on it into the scope. DO NOT use the 2 x barlow if you have one.

The end with the focuser is the UP end of the tube -- the mirror is on the bottom of the tube.

You will need to provide more detail for us to solve this problem. Are you talking about Altitude and Azimuth adjustments??

Hi, this is a real handy scope. You need to remove the disk like cover for the high polished mirror located at the but end of the scope. Then insert one of the two ocular lenses provided into the viewing aperture. Next, aim the polished mirror end at something obvious like a street light. Use the range finder located opposite the viewing aperture, (switch red button on) and align the circles with the red dot. Happy viewing!

The red dot finder is NOT lined up with the main tube. During the daytime locate a distant object with the main tube eyepiece. Without moving the telescope adjust the red dot to point at the exact same spot.

collimate your mirror.
sky and telescope shows you how to do it.
it's under 'Do-It-Yourself' section.

hope this helps :D

Most telescopes do not have a zoom-- they have different numbered eyepieces that give different magnification-- you can buy a zoom eyepiece however.

From what you describe -- put the eyepiece with the LARGEST number written on it into the telescope-- this is the LOWEST magnification. Now focus on the moon and or a distant land object during the day-- once it's in focus -- nice and sharp-- replace the eyepiece with the next LOWER number-- for more magnification. AND-- refocus the telescope for that eyepiece.

Question moved from Televisions category. Celestron Support https://www.celestron.com/pages/support Setup videos https://www.google.com/search?q=celestron+lcm76+setup ..

The Celestron manual for this scope has nothing to say, but on the underside of the focuser assembly, between the 2 focus knobs, you may see 2 screws.They might be thumbscrews or some other screwhead type. One is the adjustment for the focuser internal clearance, or looseness, and the other is a focus travel lock.If present, try backing both off 1/2 turn from tightness, and then experiment to see which is which. The focus lock will have no effect until tight, when the focuser will cease moving, as is now. The other screw will gradually remove looseness and rattle from the focuser until it just moves smoothly, with no back and forth loose feeling at the knob.If neither of these screws is visible you will have to take it to a binocular and telescope shop, where they should not charge much.

Why not look at the old battery, or look in the manual ?

It is impossible to assess the weight (or more correctly Mass of a star, as weight is a perceived function of Earth's gravity) without knowing the chemical make up of the star. That is why astronomers use the star's measured albedo to qualify and quantify them.

Read the manual. Follow the instructions therein.
