How do you set the finder scope on the Starview 150EQ. I have no adjustment options and it is not in line with the main telescope alignment. The instruction manual is totally inadequate.

Place a wide angle, that is longer focal length lens in the scope in daylight and focus it and centre on some distant object, a tree, blg, tower etc.

Then use the adjustment screws on the finder to centre it on this same object.

Change to your next higher power lens, that is shorter focal length, refocus and centre, and repeat with the finder adjustment.

Next wait for evening and a bright star or planet to appear and centre it in the finder first this time. It should be somewhere near centre in the lens also. Centre it properly in the lens and make a final adjustment on the finder.

How do i set up eye pieces and focus lenses?? Instruction manual came in chinese with no translation and we are begiiners!


During the day:
1. Point to a far (1000 meters or more) object
2. Insert the lowest power (highest number) eyepiece e.g. 25mm
3. focus on the object.
4. Align finder to match what you see in the scope.
At night.
1. Put scope out and let it reach the temperature of the outside.
2. Point finder to the moon (1st object you should always use to check scope and finder alignment)
3. Use the same low power eyepiece.
4. If everything seems fine, switch to a higher power eyepiece and enjoy the view. You may have to slightly adjust the finder to align with the main scope.
If the views are blurry, the telescope may be out of collimation. Look on the internet for generic collimation instructions.
If this still did not help. Throw the scope out! Its probably a piece of junk and will only discourage you.

I have a newtonian telescope 76mm with SR4, H12.5 and H20. I have aligned the crosses up and can see through the viewfinder but nothing through the eye piece. Ive placed all the other lenses into the eye...


YOU MUST align the small finder scope with the main tube.

Point the scope at a distant object like the top of a telephone pole. GET the top in the center of the eyepiece in the main scope.

Then without moving the scope-- adjust the cross-hairs in the small finder scope so they line up on the same object.

I have a new Brookstone compact telescope. The image in the smaller viewfinder is upside down making it difficult to line up with image in main telescope. Is this normal? And if so, any suggestions for...


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.

Telescope manuals recommend that you align the finder scope in daylight, by pointing the main 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.

I can see objects through the finderscope, but cannot see anything through the telescope. What am I doing wrong?


Your finder scope is NOT lined up with the main tube. Get a distant object like the top of a telephone pole into the eyepiece of the main telescope tube.

Without moving the scope adjust the crosshairs or the red dot onto the exact same spot. Now your finder scope is lined up with the main telescope tube.

150-1400 Newtonian telescope Set the sight scope eye piece on the moon and looked in the pl 25mm lens in the focusing tube and no image? Can anyone help Philip moondogs2@myway.com


You must align the finder scope with the main telescope tube--

During the daytime look at something far away in the main scope-- without moving the scope center the cross hairs on the finder scope.

Good luck

Set up


The finder scope may not be aligned properly with the mn telescope. In the daytime, try setting the main scope on a distant object such as a steeple or chimney in the distance then align the finder scope to point to the same object. Then at night, look at the some bright star or planet and fine-tune the finder scope's adjustment screws so the images are aligned between the two scopes.

Setting up my reflector telescope(beginner)


During the daytime focus the telescope on a distant object-- center the object in the eyepiece. Without moving the telescope adjust the finder scope by loosening and tightening the set-crews until the crosshairs are centered on the same object in the telescope eyepiece.

Your finder is not aligned with your telescope. During the day time focus on a distant small object with the telescope-- then without moving the telescope adjust the crosshairs in the finder to match the telescope.
