Celestron PowerSeeker 127 EQ 21049 (750 x 127mm) Telescope Questions & Answers
Can you describe how to
Once the scope is polar aligned move it to a named star that you can identify. Look up the RA and DEC for that NAMED star in any planetarium phone APP or a laptop running any planetarium software like the free software available at www.stellarium.org
Adjust the circles to MATCH the RA and DEC in the planetarium software, and lock them down.
Now you can use them to find other objects of known RA and DEC.

Why are the images upside
Astronomical telescopes usually show an upside down image. There is a good reason for this- erecting the image needs more bits of glass in the light path, which reduces the amount of light and increases aberrations. Even if this is only slight, astronomers prefer to avoid it, and they don't really care which way up the Moon or Jupiter appear.
It is possible to fit an erecting prism or eyepiece to most astronomical telescopes, and some of them come with one, but one wouldn't bother to do this with the small finder scope.

Hello everybody!
I have a Powerseeker
First you must line up the small "finder" scope with the main tube. Go outside during the day time and get a distant object in the eyepiece-- use the eyepiece with the largest number written on it.
Without moving the scope adjust the crosshairs on the finder scope onto the same distant object. Now you can use the small finder at night to POINT to objects in the sky.
Again put the eyepiece with the largest number written on it into the focuser. DO NOT USE the 2x barlow if you have one. Try the moon again, and turn the focuser knob until the moon is sharp and clear.

Focus knob turns but nothing moves
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.
What is the weight of the celestron next star se 8
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.
We have a celestron 114AZ telescope. we cannot see anything with it. why?
Most problems will be overcome by reading and absorbing the instruction manual.
Assuming the telescope is in good order, it must first be pointed at a light source using the spotter scope and then aligned using the lowest power eyepiece before fitting the high powered eyepiece...
You also should be in very low light conditions.
