Tasco rifle scope troubleshooting

My BSA Supersport .22 is fitted with a Tasco scope, up to now no problems,but on it's last outing when I turn the distancing ring I couldn't focus the scope and the cross-hairs move round as well

What eyepiece do you have in the scope when trying to view the sky? (in mm)
I recommend starting out looking at the moon with the largest eyepiece you have (25mm, 20mm etc.). It is an easy target and is very impressive. Stars tend to look pretty much like little points of light in a refractor such as this anyway. Pretty boring.
Try Jupiter after you've got the moon down. You can work your way to Saturn's rings after that.

A scope is a personal preference really but there are some ground rules that do need to be followed.

any scope will be effective in a good shooters hands. however there are some bells and whistles that are nice to have.

1) For long distance shooting a scope with 40 MOA is preferable this allows for 10 MOA down and 30 MOA up giving the rifle the ability to zero for any range.

2) Hold over graphs are a beauty when your in a rapid target environment. here is an example$File/rz1000_lg.gif

this is more of a hunting scope but this hold over calibration allows for rapid fire.

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.

I am thinking of buying a Tasco Telescope Model 46-11437 second-hand and am wondering what the original purchase price may have been and what problems I should know about before I buy.

Originally around $150 new. This is a wide field, low power scope. Good for the moon fair to good for planets and fair for deep sky objects (Orion Nebula and some clusters will be fine) Expect to see Jupiter and its moons but unless it is a perfect night, no detail of Jupiter's clouds. Should see the rings of Saturn also.
The scope comes with Tasco eyepieces, which are close to junk but at least they are in 1.25 in format. You can buy better eyepieces and they will work with any upgraded scopes, if you catch the astronomy bug.
The optics are fair, Tasco is not known for good optics. I would study up on collimating your scope, I guarantee you will have to adjust it.

Tasco does not sell parts. Sorry. If you can find a damaged scope for sale on you may be able to salvage the part from another used scope of the same model.

Please do not EVER buy another Tasco scope.

Can not focus telescope lens pieces do not fit

What Tasco do you own is it a refractor or reflector? Does it have a lens in front -- then it's a refractor; or mirrors, then it's a reflector.

On a refractor the eyepieces go in the back of the tube, sometimes you also have a diagonal which goes into the scope first and then the eyepiece goes into the diagonal. The diagonal is simply an L shaped device with a mirror inside that makes it easier to look through the scope when it is pointed UP at an angle.

On a reflector the focuser is on the FRONT side of the tube, and the eyepiece goes into the focuser.

Take the scope outside during the day time and practice focusing on a distant object. Put the eyepiece with the largest number written on it into the focuser or into the diagonal. This is your LOWEST magnification.

Practice focusing --- until you get used to how it is done. Turn the focuser knob to the left slowly-- if nothing comes to focus then try turning it to the right. It may take several full turns to come to focus.

At night the moon should be your first target.

Read my TIPS on my profile page.

ABOUT NOT FITTING: eyepieces come in 3 sizes, .975, 1.25, and 2 inch sizes. Measure the hole and then measure the eyepiece-- it may be that you have the wrong size eyepieces for that scope. The correct size can be purchased on line from many retailers. Here is one telescope retailer that sells eyepieces and other accessories:

My Tasco Luminova is set up right. But i am still see it upsidedown? Why is that?

Because the PICTURE that Fixya uses for the question (SHOWN ABOVE) is upside down! The silly fools have the scope pointed at the GROUND!

Turn the scope around so the focuser end is pointed up.

Like this picture:

I need a users manual for tasco galaxsee 46-060675

Do you need a users manual to ASSEMBLE the scope? Or are you looking for how to USE the scope.

This is a very small 60mm refractor on an equatorial mount. Not much bigger than a pair of 10x50mm binoculars. The binoculars would have been better for sky observing! The euitorial mount must be polar aligned with the star Polaris before it will work properly. We never recommend equitorial mounts to beginners for this reason.

Please read my TIPS in my profile page to learn how to polar align the scope, and what you can do to improve the scope.

If you need a manual for assembly you will not find one for Tasco BUT Meade has a similar scope. They all assemble in the same way. Here is the Meade Manual:

Instruction manual for 1970's custom .22 scope with BDC

Hold the outer portion of the elevation knob and unscrew the screw on top. then pull up on the outer portion and you'll see a silver screw marked with an arrow and the word "Up". Sight the rifle at a known distance and then line up the knob with that distance as you push it down on the scope and replace the screw. I have one of these and figured this out on my own, however I'm missing the mount and would like some pictures and dimensions of the mount if any of you can get some. I'm gonna be machining a new one and would like to keep it as close to the original as possible.

Lens Fogging Issue

Apparently this is NOT a waterproof rifle scope. I would return it as you will have this same problem only worse out in the field. Buy a waterproof nitrogen filled rifle scope.
