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.

Cant get an image.Is it right that the view finderimage is upside down


The image of all astronomical telescopes are upside down (SCTs are upside down and reversed). RACI (right angled, correct image) finders do produce a right-side up image. For daytime use a erect image prism eyepiece.
Follow below instructions (except 7 in your case)

  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

We are trying to test out viewing land based objects using the 30X eyepiece, which according to the instructions, should appear right side up and not upside down! This is not happening.


It's NOT really a problem. ALL reflector style telescopes show upside down images. This will not affect your star gazing since there is no UP OR DOWN in outer space. Read my tips on my profile page.

You can buy an "erecting diagonal" for terrestrial viewing- BUT this is not what an astronomical telescope is actually used for.

So align the small finder scope on a distant object like the top of a telescope pole during the day time. Point the main tube at the pole and get the tip top in the main tube's eyepiece. Without moving the telescope adjust the crosshairs on the finder scope on the exact same spot. The moon should be your first target at night and you can check and refine the finder scope on the moon.

We have our telescope set up but cannot see anything out of the lenses. we have tried all different lenses but without success. Currently there is one star we can see with our naked eye. We cannot see it...


If you look at the PICTURE in your qusetion FIXYA has the scope POINTED at the ground! :)

You have a reflector style telescope. The mirror is the bottom of the scope, and the focuser is on the UP end of the tube pointed UP. Many beginners mount these scopes UPSIDE DOWN with the focuser on the bottom instead of the top (side) of the tube.

Put the eyepiece with the largest number written on it into the focuser. DO NOT use the 2x barlow if you have one. Take the scope outside during the day time and practice focusing on a distant object. You must also line-up the small finder scope on top with the main tube.

POINT the scope at the top of a distant telephone pole. Without moving the main tube, adjust the cross-hairs on the finder scope so they point at the same spot as the main tube.

How do you use it [ operating instructions ] ?


I have never heard of this brand??? Is it a reflector style telescope like the picture?

If it is the first thing you should do is take it out side during the day time and practice focusing on a distant object. Use the eyepiece with the largest number written on it. DO NOT USE the 2x barlow if you have one. Also line up the finder scope with the main telescope tube using the top of a telephone pole a good distance away.

Center the top of the pole in the main eyepiece, then with out moving the scope line up the crosshairs in the small finder scope on the same object.

Here is a manual for a similar reflector style telescope made by Meade:

I need a manual for the deep space hunter 6 inch purchased around 2002. model number DSH-6


Why would you need a manual for a simple Dobsonian reflector telescope.

The Company does not exist-- anymore.

A manual only showed how to assemble the telescope, it DOES NOT tell you how to USE the telescope to find objects in the sky.

This is a good beginner telescope by the way. Here is how to get started using it:

1. During the day time align the small finder scope and the big scope on the same distant target. Then you can use the finder scope to locate and POINT the main tube to objects in the night sky.

Also during the day put the eyepiece with the largest number written on it into the focuser. This is your LOWEST magnification. Practice focusing on a distant object. The image will be upside down--- this is perfectly normal. Nothing is wrong with the scope.

The moon should be the first target at night.

Need owners manual for Venture RX-7 telescope


You will not find a manual. BUT you do not need one.

This is a very simple reflector telescope on an Equatorial mount. The mount must be polar aligned in order to properly use the scope. Read my TIP in my profile section about aligning an Equatorial mount.

The major steps are:

Align the small finder scope with the main telescope tube on a distant object.

Set the Declination axis to your Latitude.

Align the main tube with the axis of the mount.

Point the entire mount toward the North Star Polaris.

Use the fine RA & DEC knobs to center Polaris in the eyepiece.

See this web site and my tips--
http://www.astronomy.net/articles/4/polaralign.html

This is why we NEVER recommend an EQ mount to a beginner. Polar Alignment just introduces one more FRUSTRATION to someone new to the Astronomy hobby.

The eyepieces simply go into the focuser. The Larger the number written on the eyepiece the LESS the magnification.

Take the scope outside during the daytime and practice focusing on a distant object using the eyepiece with the largest number.

The manual WILL NOT tell you how to find those small dim objects in the sky. It's just assembly instructions.It does not tell you how to become an amateur astronomer.

Locate a local Astronomy club and seek advice from the members, who will be glad to help you with your telescope.

HOW TO USE AN ORION SKYQUEST XT 4.5 REFLECTOR TELESCOPE


During the day time line-up the small finder scope with the main tube. Use the eyepiece with the largest number written on it. Site on a distant object with the main scope. Then line- up the crosshairs on the finder with out moving the main tube so BOTH are pointed at the same object.

Locate a local Astronomy club and attend their star parties. You have a good beginners telescope by the way.

Learn how to collimate the telescope. Watch this video.

Edu science reflector telescope instructions 600x


This is a small refractor telescope-- they pretty much all work the same-- BUT don't expect to get more than 100 power out of the scope. Yes I know the box said 600 power but it's a lie. In my 8 inch telescope I rarely get above 250 power and my scope is many times larger than the one you have--

Now put the eyepiece with the largest number written on it into the telescope-- the LARGER the number the LOWER the magnification. During the day time practice focusing on a distant object --- AND line-up the small finder scope on top with the main telescope tube. Look at the top of a distant light or church steple, or telephone pole. Without moving the telescope adjust the small finder scope by loosening and tightening the screws around the tube holding the finder scope-- put the crosshairs on the same spot as the main telescope.

Now you can use the small finder to locate objects in the sky-- the moon should be your first night time target.
