Take the scope outside during the day time. Put the diagonal into the back of the scope, and then put the eyepiece with the largest number written on it into the diagonal. DO NOT US the 2 x barlow if you have one. Practice focusing on a distant object-- the moon should be your first target at night because it is large and easy to find.

Objects in the night sky are dim and tiny. Your scope must be pointed directly at them or you will not see anything.

How to use a spotting scope for shooting?


A Spotting Scope is an essential element for hunters and shooters. This small device is technically a special type of telescope used for hunting, magnifying and watching an image or object more clearly. The methods use a shooting spotting scope does not involve much difficulty.

Here is the method:


Comfortable position

For a perfect shooting experience, you need a comfortable position. If your comfortable position is unable to help you fix the targeted area, you are likely to miss the hit or glance.

Attachment of the spotting scope with the tripod

Having an accurate view of the targeted area is important. Due to this reason, shooters need to position the spotting scope with a tripod so that they can see the targeted area very clearly and accurately.

Adjustment of the magnification level

The lens and magnification level should be adjusted so that you can get the appropriate view of the targeted area.

View of the targeted area

After fixing the targeted area, you have to adjust the magnification level with the lens to view the targeted area. At the time of using scopes, you will find some problems that magnification will present. If you fix the magnification and focus firstly, you may not find the target. You have to first view the target, and you have to adjust magnification level as required. Here, you should bear in mind you will have to go with the slow magnification process because the fast magnification process cannot give the accurate target.

Adjustment of the focus
You have to know how to reset the focus because you will need to do it again and again. It may sometimes harm your eyes with the magnification level being set to high.
Focusing on target is important for shooting and the spotting scope is also important for this purpose. For acquiring a specific target, it is important to use magnification level with the spotting scope.

You should follow all the methods of using explained above. There is no alternative way to learning how to use a spotting scope for shooting except these methods.

Which is better for use, angled or straight spotting scope?


Spotting scopes are used for several purposes which includes hunting, birding, nature viewing and landscape observation and targeting any distant objects. If this device is used for capturing photos, then the combination of a spotting scope attached with a camera would be helpful for the users. A spotting scope can also be used fort target shooting on which scoring targets on a rifle or archery range. If anyone wishes to buy a spotting scope then one must.
Angled or Straight Scope
Going for a spotting scope based on the users need, the thing that will come first is choosing one between the two - angled spotting scope or straight one.
Here is the Advantage and disadvantage of spotting scope:
Straight Spotting Scopes
Advantages
  • Easier to quickly find and track moving targets like birds
  • Easier to use if you do most of your birding or game viewing from hides or using a car window clamp
  • Easier to view objects below your own level eg at the bottom of a cliff
Disadvantages
  • Can get uncomfortable during prolonged observation periods
  • Digiscoping: depending on the weight of your camera and adapter, gravity can make the set-up less stable and there could be more chance of harming the eyepiece
  • If you're above average height, it can be more expensive to buy a tripod that needs to be stable at 170cm high and above. The larger tripod is also harder to carry about.
  • Harder to view birds in the sky
  • Harder to use if you also plan to use your scope for astronomy
Angled Spotting Scopes
Advantages
  • Generally more comfortable for prolonged observation periods
  • Easier to view birds in the sky
  • You don't need to raise the tripod so high and often depending on which tripod you have, you don't even need to raise the center column which makes a big difference regarding stability
  • Many prefer an angled for digiscoping, as you can set it at a lower height on your tripod, making it easier to keep it stable, especially in windy conditions
  • Gravity helps keep the camera in place for digiscoping making it more stable and so there is less chance of harming the eyepiece
  • Easier to use if you also plan to use your scope for astronomy
Disadvantages
  • Beginners will find the angled scope difficult to trace and detect the moving targets but they will overcome the difficulties over time by being able to handle it. It is more difficult to use when an user utilize this device mostly for birding or viewing game
  • Harder to use if you do most of your birding or game viewing from hides or using a car window clamp
  • Harder to view birds or anything else that is below your own level eg at the bottom of a cliff

What is field of view in Binoculars, Spotting Scopes and Rifle Scopes?


Optical field of view (FOV) refers to the width of the area that you can see when looking through a pair of Binoculars or a Spotting Scope, quite simply, how wide an area you can see through your optics. Field of view is usually described in terms of 'linear field of view' or 'angular field of view'. Both figures essentially indicate that the field of view of the optic is a certain width, but they just use different numbers to describe this.

Linear field of view is also known as the true field of view and indicates the width (in m) of the area that you can see when standing 1,000m away from an object.
Angular field of view is also known as the apparent field of view and refers to the true angle (in degrees) seen through the optics.
It is easy to convert between the two field of vision measurements:
To convert an angular field of vision to a linear field of vision, simply multiply the angular field of vision by 52.5.
To convert a linear field of vision to an angular field of vision, simply divide the liner field of vision by 52.5.

When choosing your binoculars or spotting scope, take some time to consider where you are planning to use them, as this will indicate the most suitable field of view required to get the most out of your product. The most important thing to remember is that the larger the number is given to the field of view (FOV), the larger the width of the area you will be able to see through your scope. A larger field of view is desirable if you are planning to use your scope to watch anything that is moving quickly across your viewing area as it will make it easier to aim and stay on a moving subject. For this reason, scopes with a larger field of view are favored by people watching birds in flight, a ball at a cricket game, an athlete in a race or views from a moving car.
Don't forget field of view (FOV) and magnification are closely linked, with higher magnifications resulting in a smaller field of view. Take some time to consider whether you wish to view your subject in great detail, or would prefer to be able to keep track of it if it is moving quickly; after all, there's no point being able to see the fine detail on a bird's feather if you can't find the bird in the first place!

Feature Analysis
  • Porro Prism Lens
    Though many optics producers keep on trying to transform roof prism lens, Porro prism lenses are more affordable and light-efficient. These Porro prism lenses can display images with better contrast than roof prism variations. This is how Bushnell Spotting Scope is more reliable and affordable for its high-quality performance.
  • 20-60×65 Zoom Magnification
    The wide range of magnification allows user flexibility for long-range view finding. You can observe details with 65x zoom for long range objects. But, you can still enjoy an increased field of view with 20x zoom. This is used when separating the areas for closer zoom viewing later on.
  • 65x Lens Light-Gathering Capability
    This advanced magnification lenses can light gather at long distances. The Bushnell Trophy 20-60x 65mm Waterproof Spotting Scope resolves this issue by designing 65x zoom lens in a way that brings 17% more light than most high-zoom lenses.
    If you fully read Bushnell Trophy Xtreme Spotting Scope Review, it will support you how to setting zoom for longer distances images.
  • Waterproof Construction
    When you go out in nature, this waterproof construction anticipates you about rain or even snow. It is pretty obvious that any liquid that leaks into your scope will detract from the overall image. But many people do not consider the effects of concentration on the inside of the lens.
    This spotting scope is actually water and fog proof not only for outside moisture but also prevents lens fogging from risky temperatures.
  • Fully Multi-Coated Optics
    The multi-coated lenses prevent any reflections in the glass that can delay your view. The sunlight at certain angles can cause reflections from water or wet surfaces that prevent the clear view of the images. That is why; Bushnell uses multi-coated lenses to remove any kind of reflection.
  • Well-designed Equipment
    The tripod often needs to hide from animals, and the scope cases also need to protect their insides from both jostling and the outside elements. The Bushnell Trophy XLT comes with both a hard-side case and a soft side case. The hard side case protects you from outside damage and a soft-side case protect you from a bumpy road when you are riding.

How do I sight the telescope


The "finder-scope" as they are called can be lined up by putting a low-power eyepiece in the scope, and moving the scope (on its mount) to view a distant object such as a streetlight. An EP which gives you about the same magnification as the finder-scope is a good choice. They are mostly about x8 power.


Centre the object in the eyepiece view and then adjust the finder-scope until the object is centred in that view as well.


Repeat this with a higher power EP, then move the scope onto a bright star, and use the highest magnification EP you have to finally do the last tiny adjustment to the finder-scope.

I have a meade 40AZ-P telescope How do you set it up to view objects. It shows nothing?


This is really not suitable for viewing objects in the night sky -- except for the moon possibly. It is only 40mm ---- a pair of 10x50mm binoculars has more like gathering power than this small refractor scope.

Just put the eyepiece with the largest number written on it into the diagonal at the rear of the scope (the focuser) take the scope outside during the day time and practice focusing on a distant object. The moon should be your first target at night. Again this scope is really not suitable for viewing the night sky.

Just had a konusmotor 500 telescope and have built it to the instructions, but nothing on how to use. only a beginner but how do you increase the size of the object you are looking at,eg the moon looks the...


Are you viewing the moon through the small finder scope on top of the main tube? That is only used for aiming the scope, and has very little magnification. The moon should fill the field of view on even the lowest magnification on the main scope.

A reflector type scope has the eyepiece mount on the side of the main tube, near the top end, pointing into the side of the scope. This mount should have an eyepiece placed in it- use the one with the biggest number to start with (that will have the least magnification). Do NOT use the Barlow lens if one came with the scope. You look into the side of the tube with this type of scope, not along it.

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.

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. This scope has a motor to track the scope and keep objects in view, but you will have to get the scope set up for that for it to work correctly. Again, use the least powerful eyepiece to start. Small scopes are often advertised as having unrealistic powers (300, 500) which can never be practically achieved. You just get dim blurs.

I can't see anything out of the large scope


Use the 20mm to view an object (building, tree etc.) far away during the daytime. Align the finderscope to the object.
To view the moon, leave the scope out to equalize the temperature for at least 1/2 hour. Use the 20mm and no barlow. Point the scope towards the moon by sighting along the barrel of the scope, then use the finder to zero in on the moon. You may then switch to the 4mm eyepiece. for a more magnified view of the moon. You will have to keep moving the telescope because of the earth's rotation. The higher the magnification, the more you will have to adjust the scope. Because of the cheap finderscope, finding the planets will be difficult. Best to always sight down the length of the scope to get you close. The planets will be small and indistinct.
This is not a astronomical telescope! May be used for views of the moon but the cheap mount is not suitable for other planets. Max power would be 225x NOT 420x as advertised. The erecting prism is for terrestrial use only.
Nothing discourages an amateur astronomer more than a toy store telescope. My advise would be to use this scope for nature watching and go buy a good telescope (Meade, Celestron, Orion etc.). Even Those 60mm refractors are superior to this! A descent scope would cost a minimum of $200

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.
