Kowa TSN-55A Prominar telescope + 17-40x WA wide angle zoom

Kowa TSN-55A Prominar telescope + 17-40x WA wide angle zoom

Prominar series image quality in a very small size! This fits easily in your backpack. This new telescope uses the same technology as the larger models TSN-88 and TSN-66.

Excellent image quality! Don't let the small size fool you. The magnification here is not as high as in larger models and the light gathering in low light is less. But the image quality is probably one of the best - even if you include all telescopes from all the top brands in the comparison!

It's worth coming to the Mikkeli store to experience it for yourself!

• Integrated TE-11WZ II eyepiece
• 50% wider field of view than the previous model
• Magnesium body, both XD lens and fluorite crystal lens
• Completely waterproof construction
• Dual focus (i.e. fast and accurate focusing)
• Angled
• Length about 25cm and weight less than a kilo

The magnesium-bodied Kowa TSN-55A telescope is less than 26cm long and weighs just under a kilo. It uses the same optical coatings and fluorite crystal lens material as Kowa's top model, the TSN-99A. The light transmission of the lenses is top-notch, meaning the image is clear and image errors such as chromatic aberration (colorful error visible around details) are minimized.

The biggest change is the TE-11WZ II eyepiece integrated into the telescope. This means that this is not replaceable, but it is the same eyepiece as in other new Kowa telescopes. The field of view is a whopping 50% wider than in the previous TSN-550 telescope.

The magnesium body, which can withstand even the toughest use, is also completely waterproof and dustproof. The telescope body is filled with nitrogen gas, which prevents internal fogging. A retractable lens hood protects the front lens from rain and sun glare. In addition, the telescope has a 55mm filter thread for protective filters, for example. The lens hood is integrated and can be pulled out.

The focusing mechanism is the familiar dual-action one. This means that two focus screws are used to adjust the focus. The larger focus screw is used for coarse (and fast) focusing, while the smaller focus screw is used for fine-tuning.

The focus rollers are conveniently placed on the telescope body, making them easy to operate with your index and middle fingers. And because it is a small tube, when focusing on the tube, you can also use bean bags instead of a tripod without making focusing difficult.

In addition, next to the eyepiece there is a separate aiming eyepiece without magnification to make finding targets faster.
