1 Answer

Celestron astromaster 114 EQ (problems zooming in)

When i zoom closer to the likes of the moon or venus (or any star come to think of it) i see my circular mount from my mirror in the centre of the image! looking towards closer objects (ie land) my zoom works perfectly! is there something i'm not doing (or not set up)? any serious suggestions on solutions, I would be very grateful for!

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.

Seeing the stars


The stars will always be "points in the sky" no matter what telescope.
The stars should be sharp, focused points in the center of view (more blurry towards the edges because of the stock eyepieces and the fast telescope mirror) if not, the telescope may need collimation. (look at instructions and/or search online. Plenty of instructions on the net.)
  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

Cant see anything through the view finder


1. During the day, use the 17mm eyepiece on a object outside (telephone pole, water tower, etc) then align the finder to what you see in the scope.
2. Put in the 7.5mm eyepiece and fine align the red dot finder.
3. At night, point the finder at the moon (less than half moon or the image is too bright without a moon filter) Use the 17mm eyepiece.
4. Once you see the moon, switch to the 7.5mm lens and enjoy.
5. Download Stellarium or any free astronomy software and see what is in your sky tonight. Your scope should be able to see Jupiter and its moons easily.(Saturn, Mars and Venus when the time is right) Open clusters like Pleiades will be nice is this fast scope.
5. If stars are not sharp, you may need to collimate the scope. Look online for general instructions.

I got an inphase telescope for a present secondhand. There are no instructions and I have never used one before, could you advise me please?


The bit of information I can find on this model tells me this scope is probably a Newtonian reflector Telescope.


The following is the most basic steps I can think of to get you in the driver's seat.. by doing a few simple internet searches in regards to astronomy.. you should be able to greatly expand on my few simple tips.


The primary mirror is at the bottom.. the heavy end.. of the tube... if you can see screws holding it in place... resist the urge to "tighten them up".. doing so will probably misalign the mirror.


You should have a small finder scope mounted on the side


Near the finder scope will be the eyepiece/holder with focuser.. all this should be closer to the skyward end of the scope than the earth end of the scope.. so to speak.


As you peer into the eyepiece you are basically looking at a right angle to the primary mirror into a smaller secondary mirror which in turn is reflecting the image of the primary (bottom) mirror. By adding various eyepieces with different magnification factors you are enlarging that image.


Most folks don't realize how bad a typical looking glass mirror is..but if you look really close at the old bathroom mirror.. you will see how much the glass distorts the image reflected on the silver coating.


Which is why your telescopes mirror has a top coating of silver on the glass.. not behind the glass..


To get started..

I suggest doing all of the following things during daylight hours or near dusk on a clear nite so you can see what you are doing.. to get familiar with the scope.


Using the lowest powered eyepiece you have.. once inserted into the focuser .. aim the telescope at an object a few hundred yards away and attempt to focus..


Remember that everything will be upside down.. looking at the moon, planets and stars..it won't really matter.


Once you have managed to point and focus easily.. you can align your finder scope.. again.. using a fixed terrestrial target


Aim the scope at this object.. the further away the object is.. the better.. get the object as close to center as possible.. slightly increase the magnification if you have a stronger eyepiece.. if not.. proceed.


Fix the scopes position by tightening any set screws on the mount.


Check the position of the spotted object again ..make adjustments until you have the object centered.


Look through the finder scope.. adjust the mount screws until the object is centered in the crosshairs..


Check all settings.. your done.


Start out looking at the brightest objects in the nite sky using the lowest magnification..


Once you become familiar with how to find/spot and focus on simple bright objects.. like the moon and perhaps Jupiter... you can read various articles at websites such as Sky and Telescope to learn how to properly align your scope with the polar (north) star.. of course this depends on the type of mount.. and drive if any... Or simply enjoy point and look backyard astronomy.. some of my most fun star gazing has been using bincoulars.. a star chart.. and a lounge chair.


Remember to keep it simple at first.. be ready to dress warm.. and take your time.. your eyes will need almost 30 minutes to really adjust to nite vision..in this cooler weather it helps to let the scope cool down for a while outside (covered) to keep things aligned properly.. of course the darker it is the better the view..


Even inexpensive scopes can give a lot of satisfaction to a point... especially if it's your first..


Good luck!

Hi, a few days back I purchased Nexstar 4SE. I set it up exactly how it says in the manual still I cannot see any magnifying views from the eye piece. While aligning the telescope I can find the moon from...


Stars will always appear as points. It is not possible to magnify them enough to see them as disks because they are all extremely far away. A telescope will however show you stars and other objects that are too dim to see with the naked eye.

You will be able to see the planets as disks, and even features on the planets, such as the bands on Jupiter, the rings of Saturn and the phases of Venus, and also moons around some planets. There are other objects that will show more detail when magnified, such as nebula. You will be able to see a lot of craters and other detail on the Moon.

Your problem is simply that you are not pointing the telescope at these objects. This seems to be one of those telescopes that "automatically" finds objects, but these so called "go to" scopes only do this when they are set up properly. I can't say what step(s) you have missed, but clearly even if the scope thinks it is pointed at the moon, if you can't see the moon, it is NOT pointed there. The Moon will fill the field of view even with the least powerful eyepiece. If you are seeing stars as points, then the eyepiece is focussed and working properly.

I"ve been an amateur astronomer for "over" forty years, started when i was eight. Stars aren't that impressive, most look the same....i spend my telescope time with a cheap $200 21/2 inch "Refractor" and have seen all planets except pluto, i had to use a 41/2 inch refractor just to be able to view Neptune and just barely saw it and yes it was Blue!! Refractors are best for planet viewing. Dont waste your time with viewing Mercury or Venus...not impresive! The best looking (but not in the next few years because of ring alignment) is Saturn...hurry up and you might still get a chance to see the rings a little before they go into what i call hibernation mode, they'll make a straight inclination though the planet which makes for not so impressive views...next most impressive and one i view the most is Jupiter and its for moons Calisto, Ganymede Io, and Europa...you will always see these in different orbits. But i just use a pair or Celestron Binoculars 15 x 70s..i use them to look at the Moon, Mars, Jupiter, Saturn, Comets, overhead comunication Satilites passing bye..and the most awsome of them all the "Orion nebula" colors are outstanding, and if your real good at knowing your constellations you can locate the Andromeda Galaxy. It'll look like a buffy cotton ball with binoculars..dont view the sky ever with a full moon.it makes for poor viewing,but this is where the Reflectors like a 4"Newtonion or lot bigger like at least an eight inch Cassigrain..these telescope are made to view whats called "faint fuzzies", Nebulas, Galaxies, star clusters etc. 40 years ago i cold look up in my local skys and not have to worry about light polution..so i go out to the deserts with just my binoculars...they are so convienient. Start to learn the sky with binoculars...it"ll be well worth it! The one Great thing about binocs is that everything you view is right side up as opposed to telecopes upsidedown. To locate planets they will track within 10 degrees in the path that the sun takes. If you look and see some really bright stars that dont twinkle, chances are that it will be Jupiter, Saturn or Venus..but you will only see Venus in the early mornings or late evenings..Mars is a little trickier, sometimes its small and red and every few years it can be as bright as Jupiter when its at it closest to the earth!

I am having trouble focusing in the stars and moon


I would recomend that you start with a low power then gradually work your way up. The best advice used to be and still is... "that for every inch of aperture of the objective should equal 50x." With advances in telescope technology this is still is a good rule of thumb.

The formula is focal length of the scope (in millimetres) divide by your chosen eyepiece (again, in millimetres. Based on my TeleVue Ranger (70mm objective) and a 6mm eyepice this is what I get. (see below).

telescope focal length: 480mm / eyepiece: 6mm = 80x magnification.

This is comforfable for observing of the Moon, Venus, Jupiter, Saturn and Mars (brilliant when it made its close approach in 2003). Mercury I have omitted is because it is always close to the Sun and I do not have it on a mounting which has setting circles.

However, if I add my 2.8x Klee barlow lens then it pushes it up to 224x. But word of advice here. To use that kind of magnification the end result is awesome, but you need a perfect sky (i.e. no thermal disturbances and debris up there).

CELESTRON 127EQ faulty magnification


It won't increase viewing power by hundreds of time but it should be able to show you a close up view of the moon and planets where they look closer (or with the moon, parts of it look closer). When you say it looks further away, something is quite wrong as you know. It sounds like the eye piece is backwards in the mount? Can't imagine what else would make it smaller. Also can't imagine you could even get it in backwards. I have a scope by Meade that is essentially the same Newtonian design. Best of luck.

I have bought a Vivitar Reflector telescope and could not find instruction. Where I can find it to resolve a problem?


If it is like the picture you posted it is a refractor style telescope on an Alt Az mount. Very simple to use -- left and right--- up and down.

However you also need a star chart to find things in the sky-- download one for free at: http://www.skymaps.com

Also try to find a local Astronomy club and attend some of their meetings and star parties. Your first sky object should be the moon -- the next time it is up at night.

Jupiter and Venus are also up right now.... check the star chart above.

Viewing planets and stars


The problem is you are way out of focus. Turn the focus knob alot, until the star image gets much much smaller. Keep going until it looks like a pin point or a star!. The spider vane and center black dot will disappear. This black dot is actually the secondary diagonal mirror reflection in the primary mirror. The peace signs are the secondary supports. Use the lowest power eye pieces. I would not use the Barlow lens that comes with this scope as it very poor quality. Also, using this high power with this small an aperature (tube diamter) & unstable mount will be very difficult indeed. Invest in some wide angle, long eye relief low power lens. Use these for a while before going to higher powers.
