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) Eyepiece lock mechanism Strong, lightweight and portable 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.

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.

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.
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.

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.

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 Kowa TSN-CV88 Eyepiece protector Kowa TP-105FT Protective filter
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.
