Hi, poor focus & viewing field upside down with & without eyepiece. can you please provide solution tasco 302045 telescope

hi Bienfechiva.
this is all i could find from the internet.
( Put the eyepiece with the largest number written on it into the focuser. ... Turn the focus knob back and forth slowly until the image is in sharp focus.)
as you say you have the manual so no point it sending you to that link.
so go to this link and see if it helps.


Tasco Galaxsee 46114500 500 114mm Telescope No image through the eyepieces...

The eyepiece size (diameter) is the standard 1.25 in.
Erecting eyepiece adapters can be used with this scope.
maximum magnification is 250x therefore highest eyepiece would be 3.6mm
most useful magnification of any scope is 150x (900/150= 6mm eyepiece
Eyepieces provided with scope (Huygens type) have a narrow field of view and are relatively poor for astronomy but should be fine for terrestrial viewing

New telescope users are taken by surprise at the difficulty of just pointing the telescope in the right direction to see anything. The field of view is quite limited, especially if you are using a high power eyepiece. The higher the power of eyepiece on a telescope, the dimmer the image, the more difficult to aim it at any chosen object, and the more difficult to focus. When the scope is not focussed, even if there are stars in the field of view, they will only be faint blurs.

It is best when you are starting out with a telescope to try it with the least powerful eyepiece (the one with the highest number) to begin with, until you become more familiar with how it works. Do NOT use the Barlow lens if one came with the scope.

The finder scope is meant to help you get the main scope lined up on the object you want to view, but it won't be any use in pointing the telescope until you adjust it to precisely line up with the main scope. Telescope manuals recommend that you do this in daylight, by pointing the scope at an object on the horizon and adjusting the finder to match (never point a telescope toward the Sun!). Once you have a tree or mountain peak in the center of the main scope's image, you can then adjust the screws around the finder scope to get the crosshairs (or red dot) centered on the same object. It is very difficult to do this job in the dark, especially as objects in the sky are constantly on the move.

You will find that there is a very wide range of movement in the focus mechanism, because different eyepieces focus at different points, but the actual focus range for any eyepiece will be a small part of the overall range afforded by the focusing mount. It is much easier to familiarise yourself with this in daylight.

At this point you will learn that 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.

Once you have done the above, you can try the scope at night, on an easy to find bright object like the Moon. Looking at random stars will probably be disappointing, as they don't look different under magnification. You will have to find planets, star clusters or nebula to see anything interesting. You will also find the the object you are looking at swims out of the viewing field, and you must continually move the scope to follow it. This will be more pronounced at higher magnifications. Again, use the least powerful eyepiece. Small scopes are often advertised as having unrealistic powers (300, 500) which can never be practically achieved. You just get dim blurs.

There is an excellent website for beginner telescope users at THIS LINK

No the red pointer is not necessary- BUT you will have a harder time aiming the telescope.

Objects in the sky are very tiny. The field of view is about the size of the tip of your finger held at arm's length. VERY small! This is the biggest problem for beginners, the telescope must be pointed DIRECTLY at the object in order to see it. Try for the moon first at night, since it is a BIG target.

Put the eyepiece with the largest number written on it into the telescope focuser. DO NOT use the 2x barlow if you have one. Practice focusing during the day time on a distant object. The image will be upside down, but this is normal.

Read my TIPS on my profile page, and these:

Put the eyepiece with the largest number written on it into the focuser. I believe you have a REFLECTOR style telescope with a 3.5 inch mirror in the bottom.

Point the focuser end toward a distant object and practice focusing during the day time.

Later you can try the higher power eyepieces with the SMALLER numbers written on them. I belive one of the long pieces is a finder scope that mounts on top. AND the other is a 2x barlow which multiplies the eyepiece power by a factor of 2 times. Don't use the barlow. You will not need it.

The image will be upside down, which is normal for an astronomical telescope.

Astronomical telescopes ALWAYS show images upside down. There is no up or down in space!

Put the eyepiece with the largest number written on it into the telescope. Go outside in the day time and practice focusing on a distant object.

You do realize that you bought a 60mm telescope. Not much bigger than your normal pair of 10x50mm binoculars.

the scope is made for both terrestrial viewing and astronomical. In order to see terrestrially upright, you need an inverting STAR DIAGONAL. The eyepiece will do nothing for inverting the image. you might have 2 diagonals in the kit that came wih the scope. the diagonal is the part that fits into the scope. then you place the eyepiece in the diagonal. if you have 2 diagonals , one is a 90 degree angle,(astronomical) and one is a 45 degree angle, (terrestrial). the eyepieces change the magnification of the image. the bigger the number (9mm, 20mm, 26mm,) the smaller the image. the smaller the number , the bigger the image gets. the number is inverse of the image. Hope this helps.

You will not be able to get parts from Tasco-- however many things can be repaired with parts from a well stocked hardware store.

Rather than trying to fix a broken eyepiece look at this web site from some low cost plossel style eyepieces -- not very expensive. You need a 20mm and a 12 mm.

Probably -- the 4mm gives too much magnification for you telescope-- difficult to focus or find thing in the sky-- you should also have had an eyepiece somewhere between 17mm and 24mm for lower power viewing.

What eyepieces sizes have you used?
Try using the largest eyepieces you have (20mm, 25mm or higher) for a wide field of view. If your eyepiece is to small (maybe 15mm or below) you will have too much magnification and the moon will be a blur.
