Questions & Answers
Looking for a good viewing scope to Puget Sound water activity (boating, mountains) at a range of 5-20 miles. Would this scope or the 880 model work? Expert Answer

Yes, these would be amazing spotting scopes for that purpose and realistically any job. The Kowa spotting scopes are some of the best in their respective price ranges. The 880 series would technically provide you with a better image as they have a larger objective lens which would be best for high magnifications. The 770 series is still great, but the larger objective of the 880 will be better at top magnifications.

I would like to buy the Kowa TSN-773 with a fixed 30x wide view eye piece. Do you have an eyepiece and adapter that is really optimized for this scope Expert Answer

The fixed 30x wide view eyepiece has been discontinued, MPN: TE-17W. I've provided links below to a fixed 25x eyepiece and a variable 25-60x wide angle eyepiece that are available.

Product Info for Kowa 77 mm High Performance Spotting Scopes Prominar TSN-770 Series - Waterproof/ Fogproof Spotting Scopes

These Kowa 77mm High Performance Prominar TSN-770 Series spotting scopes feature large, oversized objectives. Indeed, this Spotting Scopes "eye" sets the Kowa TSN-770 Spotting-Scope apart from the competition. For birders and hunters alike, the Kowa TSN-770 spotting scope redefines clarity with its large Kowa 77mm objective lenses crafted to Kowa Optics's exacting standards for resolution and contrast. Add Kowa's new C3 fully multi-coated lens coating system and you have performance that must be seen to be appreciated.image

Of particular note is the new Kowa XD (extra low dispersion) objective on the TSN773 and TSN774 with its huge 77mm diameter objective. The result? Images so perfect in color and astounding for resolution and brightness that you will never go back to a smaller Spotting Scopes.

And why should you? The Kowa 77mm Spottingscope is also one of the Spotting Scopes in its class, thanks to the rugged magnesium alloy body. It is also amazingly compact for a Kowa 77 mm spotting scope at only 12.5" (not including eyepiece) and, like all premium Kowa spotting scopes, the Kowa TSN-779 spotting scopes are fully waterproof and nitrogen purged. Needless to day, all Kowa TSN-770 spotting scopes are designed for a lifetime of hard use.

The Kowa TSN-770 Spoting Scope series also introduces the new Kowa dual focusing system. Use the outer knob to go from minimum focus to infinity in only a couple turns or fine tune your focus to see that last scintilla of detail or sharpen that image for digiscoping. Focusing is typically Kowa Optics - smooth and sure.

The new Kowa TSN-770 Spottingscope also introduces a new line of Kowa Eyepieces for TSN-770 and TSN-880 Spotting Scopes, as well. (Please note that eyepieces must be purchased separately - they are not included with the Spotting Scopes.) These include a 20-60x zoom, a 30x wide angle and a 25x long eye relief model. These are state-of-the-art, fully Kowa waterproof eyepieces designed to bring out the best in the new Kowa 77 mm Spottingscopes and Kowa spotting scopes 88mm. Kowa Optics fans have been asking for an eyepiece locking mechanism and Kowa has been listening. The new 77mm and 88mm Kowa spotting scopes and eyepieces also feature an eyepiece locking mechanism to securely lock the eyepiece on the Spotting Scopes while in use.

Kowa also offers converters (not included) which allow you to use older Kowa eyepieces in the new 770 or 880 series. For Kowa 600/660 series eyepieces, order the TSN-EC3 adapter. For Kowa 820 series eyepieces, order the TSN-EC2 adapter.

Of course, Kowa and digiscoping go together like shorebirds and a wetland. Kowa offers a complete range of digiscoping adapters (not included) which allow you to use nearly any Spotting Scopes on Kowa spottingscopes, including the new 770 series or 880 series.
