I have a Kowa TS 601 with a 60mm Multi coated Lens. There is a small spot about 4mm in diameter on a lens inside the scope, looks like the the coating is blistering. I have been told this is a fungus that started when the scope was stored in a safe. Can this be fixed and will it get worse? Thanks Denis

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.

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.

could you please let me no haw to work the ray cop we have no instrutions thankyou sonia holt

I am assuming by "lens" you mean eyepieces.

You don't need to get Vivitar brand eyepieces to get additional ones for your telescope. I'm not sure of the specifications for this particular telescope but in general they come in two barrel sizes for the eyepieces. The diameter of your eyepiece is probably 0.965" but could come in the more standard 1.25". You can measure the diameter and determine this quickly.

Once you know the diameter to shop for you can look for the focal length of the eyepiece you wish to purchase. They are rated such as 4mm, 10mm, 25mm, etc. The smaller numbers give you higher magnification. You can calculate the magnification by dividing the telescopes focal length by the eyepiece focal length. For example, let's say your telescope is has a focal length of 360mm and you have an eyepiece rated 10mm. Divide 360 by 10 and that gives you a magnification power of 36.

You can find eyepieces at many telescope dealers on the internet. Your selection will be far less if you use 0.965" eyepieces. You can purchase 0.965" to 1.25" adapters so that you can use the larger eyepieces with your telescope. However, on some telescopes the adapters will cause the new eyepiece to not come into focus.

You'll also find that eyepiece prices go all over the place. A good general purpose eyepiece is a type called the Plossl. The better eyepieces have more coatings too that allow more light to get through to your eye. You'll find these listed with terms like "fully multi-coated".

I hope this helps.

Good luck and clear skies!

No if the problem is the screen, you will need to replace the entire screen assembly. some screens come in two parts. The inside of the screen is called the freznal lens, the outside of the screen is called the lenticular lens. Good Luck
