There is a guy on ebay advertising scope repair, I talked to him, he sounds like he knows what he is doing. But as far as your scope goes, I don't think I have ever seen a scope go through the entire range and stay sharp unless it cost $1,000, Mine fuzzes out instantly, I just keep it on the clearest setting and leave it there, How many chances or how many times do you shoot it at game and have time to do anything with the scope. I barely have time to aim. Anyway, you might check him out. He might not be advertising all the time. Hope this helps.

How to Spotting Scopes Work?


Spotting Scope is a type of telescope typically used for observing wild animals and birds. A spotting scope features more magnification than a conventional binocular but less than an astronomical telescope.
The utility of a spotting scope becomes most obvious when the identification of an animal going in a large herd is required. Figuring out a specific animal from other look-alike animals becomes easy with such a device. For digiscoping purposes, few things can beat the power of spotting scopes. It is possible by using binoculars or telescopes to take a closer look at birds or other animals, but if you want a precise view of your target animal, a spotting scope is preferable.
Spotting Scope Features Explained
  • Objective lens
    Objective lens, also known as the Front lens, determines the image quality at higher magnifications. The diameter of this lens ranges from 50-100mm in size. It is also called "Aperture" of the lens. It is wise to buy the highest size of the objective lens considering its weight. Larger lenses allow to pass more light and create more bright images. This means you will get higher image quality with the larger lenses.
  • Lens Coating
    Manufactures often apply the chemical coating, which is known as Lens Coating, on the lens to reduce noise and increase light transmission. They also offer "fully coated," "multi-coated" and "fully multi-coated" lens to improve image quality. The premium quality spotting scopes' lenses are multi-coated with multiple layers on the surface.
  • Focusing
    There are two types of focusing mechanism in the spotting scopes such as Helical and Knob focusers. The focusing characteristics determine how quickly you can focus on the object with maximum precision. Between these two options, the helical focuser is the finest option for birding as it can change magnification rapidly along with the movement of the bird. For hunting or spotting slower animals, Knob focuser is best as it gives you more precise information than the former one.
  • Eye relief
    The eyepiece remains at a little distance from the users' eyes. This distance is called the eye relief where the light rays transmitted from the object pass to enter into your pupil. The comfortable eye relief distance is about 15mm to see the full field view. This feature is very important for those who wear eyeglasses. Nowadays, manufacturers are offering long eye relief for those who need to wear eyeglasses for convenient viewing.
  • Image Quality
    You might have seen some designation on the glass label of the spotting scope such ED glass, APO glass, HD glass, Fluorite glass. These special qualities of glass will cost you more but create a huge difference in image quality comparing low-quality lenses. Remember, you must pay for the good quality images when it comes to buying any types of optical instruments.
  • Magnification
    The magnification of spotting scope is higher than standard binoculars and varies between 15x to 75x. The power of the eyepiece determines the magnification of the scope. The important fact you should know that image quality drops off as the magnification goes up. Even premium quality scopes also lose a little quality at the highest magnification.
The condition of the atmosphere has effects on birding, hunting and digiscoping too. Humidity, ever-moving air, dry climates, dust and so on hinders the magnification and image quality at large.

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.

    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.

I just purchased a Venture RX-7 reflector telescope at the thrift store. Got home and it's missing the eye piece lenses. Anyone know where I can order these? Any help would be appreciated! Thanks!


With an aperture of 110 mm or so, the absolute largest useful magnification with this scope is about x 220 (certainly not 375 like thay say). However at this limit the image is dim, difficult to focus, and jumps around with any vibration. A more practical limit is about x 150 or so, which is attained with about a 4mm eyepiece.

I'd suggest 3 EPs in the range 5 - 30 mm. Alternatively buy 2 EPS and a x 2 Barlow Lens (This is a magnification multiplier, placed between the scope and EP, to double the magnification of that EP). A 10 mm Plossl EP and a 30-32 mm will give a good spread with the 2 x Barlow.

Even tho the scope is a budget model, a better lens will get the most out of it. . You will soon want a better one.

My barlow lense is making it hard to focus


Only answer is depends on your optics. Maximum practical magnification is 50x per inch of aperture on very good conditions.
If you have a store brand telescope, the optics are poor (both the scope and the optics) it can't handle the magnification.
High magnification requires a good , clear night.
Allow your scope to reach thermal equilibrium before viewing.

I am able to see with the 20m Lens but once i insert the 5mm Lens it looses focus and i cannot see anything, i tried adjusting the focus again with no success. The worst thing that even at day light i...


That's because the 5 mm is too much magnification for your small telescope. Maximum magnification is a function of APERTURE. Which is how big is the front lens or the mirror.

Your scope has about a 2 inch aperture, so the maximum posiible magnification is about 100 power (if it is like the one in the picture above)

50 times aperture (2 inches)-- 100 power

It will only achieve 50 times if the optics are perfect and the sky is very transparent and stable. Usually only 30-40 times is all you normally get.

Lens SR6


That's because it is TOO MUCH magnification for that small aperture telescope. This is one of the most common problems for beginners. They believe that you need a lot of magnification to see objects in the night sky. In my 8 inch telescope I rarely go over 120 power -- magnification is the least important property of a telescope. Aperture and good optics are much more important.

What is the distance at Macro mode?


In wide-angle macro mode, the minimum focus range is as close as 30cm from CCD (21cm from the lens front.) At this point, the magnification is 0.03x (equivalent to 0.12x in 35mm format).(Focal length is 7.2mm. At maximum magnification 283mm x 213mm of the subject can be captured.) In telephoto macro mode, the minimum focus range is 25cm from CCD (13 cm from the lens front) and the magnification is 0.18x (equivalent to 0.7x in 35mm format). (Focal length is 42.7mm to 50.8mm. At maximum magnification 52mm x 39mm of the subject can be captured.)
