chromatic aberrations, high light transmission, and improved color
rendition, resolution, contrast, and clarity. Additional design elements
include a specially designed ring and bayonet mount that allows the use

Optical Performance
- Powerful
30-70x wide angle eyepiece allows you to scan the terrain for subjects
on low power with the ability to zoom in and make detailed observation
and positive identification
- Front XD lens is made of extra-low
dispersion glass and the secondary is made of fluorite crystal glass
creating an optical path free from chromatic aberrations at even high
magnification with high contrast and crisp clarity
- Massive 99mm objective lens delivers outstanding low light performance with exceptional detail
- Anti-reflection
fully multicoated lenses maximize light transmission and improve color
rendition, resolution, contrast, and clarity
- Proprietary KR
coating on the exterior of the lens actively repels dirt, moisture, and
dust from collecting on its surface to ensure clear views
- 105-foot field of view on 30x, 60 feet on 70x
Use and Handling
- Eyepiece
socket is set at a 45° angle to the body, putting the user's head in a
comfortable viewing position whether they are standing, sitting, or
lying prone
- Dual-focus system: Quick (coarse) focus allows for
fast action to bring your subject in to detail in just a few smooth
revolutions and Fine focus gives pin-point, finger-tip control offering
precise focusing accuracy with minute adjustments possible, even when
wearing gloves—increasing performance for applications such as
digiscoping when accurate focus is critical
- Eyepiece quick
release button allows the eyepiece to be removed smoothly for quick
eyepiece or adapter changes without compromising on a secure connection
to the scope body
- Tripod mount has a removable screw that allows
the spotting scope to be attached to either 1/4"-20 and 3/8"-16 heads
and quick release plates
- The orientation of the scope can be
changed with the release of a locking button for precise eyepiece
placement to improve viewing comfort
- An easily accessible collar
on the eyepiece mount allows for quick connection of current Kowa
System accessories, including adapters for digiscoping and a 1.6x
extender
- 105mm objective filter thread allows for a protective
or UV filter to be added—the sunshade can still be used even with a
filter installed
- Lens hood has a built-in aiming sight as a visual aid to assist in finding a subject more rapidly
Construction Details
- Compact design measures under 15" long
- Lightweight, strong, and corrosion-resistant magnesium alloy chassis
- Nitrogen-filled
and O-ring sealed to protect from the elements—chassis is resistant to
internal fogging in extreme conditions and waterproof
- Smooth ergonomics make it comfortable and easy to use out in the field for long periods of time
- Smooth
twist-out sunshade helps to eliminate glare from the sun and reduces
exposure of the objective lens to elements such as moisture, grit, and
sand
Key features Kowa TSN-99A Prominar:
- Large 99mm 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. - Eyepiece lock mechanism
The eyepiece bayonet mount now has an attractive feature. An
eyepiece locking mechanism has been added to the holder to prevent the
eyepiece from being lost or unexpectedly falling out. - Strong, lightweight and portable
Thanks to a 100% magnesium alloy body, the TSN-99 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. - 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

Extender
When a Kowa TSN-EX16 extender
is placed between the Kowa TSN-99A 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-99A 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-99A can even be used for deep sky observations.
|
|
Digiscoping Adapter
It is also possible to use your Kowa TSN-99A 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-99A 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.
|
|
TSN-DA10
|
The TSN-DA10 is perfect for
the compact and lightweight Micro Four Thirds cameras. Using the
TSN-DA10 and an optional adapter ring, everything is ready for use
within a minute. The optional adapter ring is available in various
sizes, depending on the filter size of your lens:
AR28/30/30.5/37/43/46/52/55/58/62/72mm.
|
|
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-99A by means of a TSN-AR11WZ adapter ring and the whole thing is
ready for use.

Protective equipment
To protect your valuable Kowa TSN-99A, you can choose to complete it with the accessories listed below:
- Kowa C-991 water-repellent Stay-On Bag
The water-repellent bag has been specially designed for the Kowa
TSN-99A and provides good protection during use and on the move. It
comes with a shoulder strap that allows the spotting scope to be carried
close at hand at all times and allows quick observation. The bag can
remain wrapped around the scope while in use. The covers of the
objective lens and eyepiece can be removed very quickly and all controls
remain accessible. - 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-105FT 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-105FT 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-99A 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.
