Kowa spotting scope TSN-88A Prominar

Precise focus

The dual focus system is one of the defining features of Kowa flagship spotting scopes, highly engineered to give ultimate control, the TSN-88A Prominar is no exception. Operation is flawless and precise, quick focus allows for fast action to bring your subject in to detail in just a few smooth revolutions, whilst fi ne focus gives pin-point fingertip control offering the ultimate in focussing accuracy.

Compability

Cross compability is a fundamental feature of all Prominar spotting scopes. The TSN-88 Prominar accessory collar and bayonet mount is 100% compatible with our Kowa System accessory range, giving you access to interchangeable eyepieces and accessories, creating a truly flexible optical tool that can be used for many applications. The spotting scope body allows connection of our Prominar eyepieces including the 25-60x TE-11WZ II wide zoom and the Extreme wide 35x TE-80XW.

If you own historical TSN-880/770 eyepieces – rest assured, they will fi t and work perfectly with TSN-88 Prominar. Add the EX-16 1.6x extender for increased magnification for long range applications, attach the latest smartphones and digital camera bodies with our easy-to-use digiscoping adapters for super telephoto photography. Even insert astronomical eyepieces and push the boundaries of this planet to the next.

The Kowa Spotting Scope TSN-88A Prominar is the improved successor to the Kowa TSN-883 which has been a leading model in the field of spotting scopes since 2006. Kowa has provided the lenses and prism of the TSN-88A with new and improved coatings. With this, Kowa succeeded in obtaining an even higher light transmission. Than its predecessor and also provides the most natural colours across the entire colour spectrum.

In addition, the TSN-88A Prominar now benefits from 100% magnesium alloy, making it not only stronger but also lighter than its predecessor. The TSN-88A is easy to carry and has a fully waterproof and nitrogen-filled housing. An upgraded Kowa KR coating on the optics makes the scope incredibly reliable and robust.

Just like the TSN-883, the body is equipped with a large 88mm pure fluorite crystal lens which, in combination with a Kowa XD lens, delivers superior low-light performance. This special combination, plus the improved optical coatings, virtually eliminates chromatic aberration, even at high magnifications. Equipped with a dual focus mechanism, the TSN-88A allows fast and accurate focusing with just your index finger - in just a few smooth turns. The fine focus mechanism provides the final control for razor-sharp viewing.

Kowa TSN-88A Prominar

You are now looking at the Kowa TSN-88A Prominar spotting scope. Note that you still need to add your own eyepiece. You can choose between a Kowa TE11WZ II with 25-60x magnification or the TE-80XW. The TE-11WZ II is a zoom eyepiece with a magnification of 25-60x, while the TE-80XW has a fixed magnification of 35x, but with a wide angle of no less than 80°. The large field of view makes this eyepiece ideal for digiscoping!

Both eyepieces are fully waterproof and feature a three-position Twist-up eyepiece ring. This allows you to adjust the distance between your eye and the eyepiece. Thus, both glasses and non-glasses wearers have a pleasant viewing experience.

Check out the specifications of the TSN-88A in combination with these eyepieces further down the description. If you want to buy the 88A in combination with the TE-11WZ II eyepiece, find the kit under optional accessories.

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-88A/88S, 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-88A Prominar:

• Large 88mm 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-88 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 95mm filter thread on the body of the TSN-88A, 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

Astro Adapters

With the use of a Kowa Astronomy adapter, the TSN-88A can also be used for night-time celestial observation and photography. For this purpose a universal 1.25" astro eyepiece can be used.

Digiscoping Adapter

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-88A, 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.
• Kowa TP-95FT Protective filter
  Using a protective filter for the lens reduces the risk of damage to the lens and avoids costly repairs. This can extend the life of the spotting scope. The Kowa TP-95FT protective filter has oil and water repellent coatings and ensures that sand and sea salt do not get on the lens. This keeps the objective lens with the special coatings undamaged.

Damage to the objective lens can drastically reduce optical performance, which also causes costly repairs. Precisely because the TSN-88A is equipped with a lens made of pure fluorite crystal. Often, the only option left is to completely replace the entire lens. That is why using protection is advisable.
