Kowa Spotting Scope TSN66A Prominar incl. TE-11WZ II WA Oculair

Do you like to get out in nature? And want to get around easily? Then Kowa has added a new spotting scope to their prominar series. The Kowa Spotting Scope TSN-66A Prominar is a compact variant with the same fluorite crystal lenses and coatings as the well-known TSN-88A. So you are assured of even higher light transmission resulting in a spotting scope that delivers even higher levels of light wavelength transmission than comparable 66mm objective lens models. It provides nature's most natural colour across the entire colour spectrum.

In addition to its compact size, you benefit from a lower weight due to a 100% magnesium alloy body and it is also stronger overall. So the TSN-66A is easy to carry and has a fully waterproof and nitrogen-filled body. An upgraded Kowa KR coating on the optics makes the scope incredibly reliable and robust.

Like the TSN-88 and TSN-99 variants, the body features a pure fluorite crystal lens which, when combined with a Kowa XD lens, delivers superior low-light performance. This special combination, plus enhanced optical coatings virtually eliminates chromatic aberration, even at high magnification. Because the TSN-66A is equipped with a dual focusing mechanism, the image can be quickly and accurately focused with just your index finger - in just a few fluid revolutions. The fine focusing mechanism provides the final control to view the image razor-sharp.

Kowa TSN-66A with TE-11WZ II WA eyepiece

This kit comes with the Kowa TE-11WZ II wide-angle eyepiece. This eyepiece has a magnification of 25x-60x and features two XD lenses, so the images are displayed with excellent sharpness. The eyepiece is fully waterproof and equipped with a Twist-up eyepiece ring with three positions. This allows you to adjust the distance between your eye and the eyepiece. In this way, both spectacle wearers and users that do not wear glasses have a pleasant viewing experience.

Fluorite Crystal "Prominar" Lens

Chromatic aberration occurs due to the diffusion of light and the different wavelengths of light that concentrate at different positions, which can result in a red or purple border around the subject. The optimal optical material to minimize chromatic aberration is Fluorite Crystal. For the convex lens of the TSN-66A/66S, a Fluorite Crystal with extremely low dispersion characteristics is used. Instead of an ordinary optical glass lens, the hollow lens in combination with the Fluorite Crystal lens is made of glass with special dispersive properties to further reduce chromatic aberration. This combination virtually eliminates chromatic aberration and redefines the standards for color brilliance.

Fluorite crystal is only used in the top models of Kowa.

Key features Kowa TSN-66A Prominar:

  • 66mm large fluorite crystal lens
  • The fluorite used as an optical lens is an artificially grown monocrystal with "ultra-low dispersion", a property that ordinary optical glass does not have. It is an ideal lens material that almost completely eliminates chromatic aberration (colour blurring). The fluorite crystal produced by the advanced processing technology Kowa has built up over the years guarantees the ultimate viewing experience.
  • Dual focus mechanism (Quick and fine focusing)
    The fast focus, with a large and easy-to-turn knob, will focus in two revolutions from infinity to five meters. The fine focus, with smooth movements and great precision, is extremely useful at high magnifications and for digiscoping.
  • Fully Waterproof and Nitrogen-Proof
    The body is completely sealed to protect it. The robust construction can withstand the toughest conditions. This provides confidence and a sense of security.
  • KR Coating
    The objective lens benefits from enhanced protection by the upgraded KR coating. The KR coating actively repels dirt, moisture and dust from the surface.
  • Sun shade
    A smoothly rotating sun shade helps eliminate glare and also reduces the exposure of the objective lens to the elements, such as moisture, grit and sand.
  • Eyepiece release button
    To release the eyepiece smoothly, the release button has been redesigned. This makes it even easier to quickly change the eyepiece or adapter without compromising a secure connection to the body.
  • Strong, lightweight and portable
    Thanks to a 100% magnesium alloy body, the TSN-66 Prominar series is one of the most compact and lightweight spotting scopes of its size. A fully waterproof and nitrogen-sealed housing plus Kowa KR coating on the optics makes the spotting scope reliably robust.
    Another great advantage of magnesium alloy is that there is no turbulence in the body. The light rays pass straight through the body and the image is incredibly quiet.
  • Filter thread
    There is a 72mm filter thread on the body of the TSN-66A, which can be used to add a protective or UV filter for enhanced protection.
    The sun shade can still be used even with a filter.
  • Designed for digiscoping
  • 100% compatible with the KOWA SYSTEM. Easily change eyepieces, accessories and use digiscoping adapters for DSLR cameras and smartphones. Create a truly flexible optical instrument for many applications.
  • 10-year warranty

Eyepieces

An eyepiece should not be missing when purchasing a Spotting Scope. Without an eyepiece you can't see anything. Below is an overview of the eyepieces that fit the TSN-66A with the corresponding specifications:

SPECIFICATIONS IN COMBINATION WITH KOWA TSN-66A
  TE-11WZ II TE-80XW
 
Magnification 25x 60x 35x WIDE
Eye relief in mm 17,0 17,0 17,0
Exit pupil in mm 2,6 1,1 1,9
Brightness 6,8 1,2 3,6
Twilight factor 40,6 62,9 48,1
Field of view in ° 2,4   1,3 2,6 
Field of view / 1000m in m 42,0 23,0 45,0

 

Extender

When a Kowa TSN-EX16 extender is placed between the Kowa TSN-66A and the eyepiece, the magnification is increased by as much as 1.6 times. In combination with the TE-11WZ eyepiece, a magnification of 40-96x can now be achieved.

Astro Adapters

With the use of a Kowa Astronomy adapter, the TSN-66A can also be used for night-time celestial observation and photography. For this purpose a universal 1.25" astro eyepiece can be used.

Two variants are available; the TSN-AS1.25K has knurled screws with which eyepieces can be tightened by hand. This allows you to quickly change eyepieces. The TSN-AS1.25G is supplied with an Allen key. The advantage is that there are no protruding screws visible.
When the TSN-EX16 extender is combined with an Astro adapter, the TSN-66A can even be used for deep sky observations.

Digiscoping Adapter

It is also possible to use your Kowa TSN-66A as a powerful telephoto lens in combination with your DSLR or system camera or even in combination with your smartphone. In this way you will be able to capture the most detailed and vivid photos of subjects you would otherwise not be able to get close enough to.
 
TSN-PA7A
 

By using the TSN-PA7A, you connect the TSN-66A directly to your DSLR camera by means of an optional T2 ring. This creates a powerful yet lightweight and compact telephoto lens compared to traditional telephoto lenses.

Designed for use with Kowa's TE-11WZ II zoom eyepiece, the design makes full use of the eyepiece's zoom range, up to a focal length of 2570mm.

Smartphone Adapters
If you would like to make photo and video recordings with your smartphone, this can be done by using a Kowa Smartphone adapter which is specially made for your smartphone. This smartphone adapter is a protective cover that can remain in place around your smartphone and offers protection against falls and knocks.

This smartphone adapter simply slides onto the eyepiece of the TSN-66A by means of a TSN-AR11WZ adapter ring and the whole thing is ready for use.

If no adapter for your smartphone is available, please inform us about this. In many cases it is no problem for Kowa to develop an adapter for your smartphone.

Protective equipment

To protect your valuable Kowa TSN-66A, you can choose to complete it with the accessories listed below:

  • Kowa TSN-CV88 Eyepiece protector
    This eyepiece protector prevents scratching of the eyepiece lens or its coating due to unfavourable conditions or transport. By using an eyepiece protector, costly repairs can be prevented.

Tripod use

When looking through the spotting scope for long periods, it is wise to use a tripod. A tripod allows you to fully focus on the subject. The Kowa TSN66A spotting scope is equipped with both 1/4" and 3/8" threaded connections. However, it is important to buy a tripod that has the right height and perhaps choose one with a fluid-damped head. A tripod with a fluid-cushioned head moves more fluidly and prevents the spotting scope from overshooting once you have the subject in focus.

 

Included:

  • 1x TSN-66A body
  • 1x TE-11WZ II 25-60x Zoom eyepiece
  • 1x Objective lens cap
  • 1x Eyepiece cap
