Kowa PROMINAR TSN-88A ZM SET with VEO 5 264CV14 Spotting Scope Kit

The Complete Kit for Demanding Observation

This kit provides everything needed for high-magnification terrestrial viewing right out of the box. Kowa describes its PROMINAR scope and Vanguard tripod kits as everything nature enthusiasts need for clear, detailed viewing: a PROMINAR spotting scope, a wide-angle zoom eyepiece and a matched Vanguard tripod, for steady, vibration-free viewing right out of the box, for beginners and experienced observers alike.

Whether you are tracking distant wildlife, identifying subtle plumage details on birds, or capturing ultra-telephoto images through digiscoping, this package is built for clarity and reliability in the field.

PROMINAR Optics: An 88mm Pure Fluorite Crystal Objective

At the heart of the TSN-88A is an 88mm objective lens crafted from pure fluorite crystal. This exotic material has dispersion characteristics that optical glass cannot match, virtually eliminating chromatic aberration (color fringing). The result is breathtaking contrast and color fidelity, rendering subjects with a clarity and accuracy that makes them appear as if seen with the naked eye.

Kowa pairs the fluorite element with an XD concave lens and has improved the optical coatings applied not only to the lenses but also to the prism. The result is higher light transmission than the previous model across the entire color spectrum, which helps in the low light of dawn and dusk and brings out subtle color variations and fine details.

Dual Focus System: Pinpoint Control from 5m to Infinity

The TSN-88A is equipped with a dual focus mechanism, allowing for rapid and accurate focusing. The focus knob has a two-step mechanism, one for quick focusing and one for fine focusing.

When a subject is well out of focus, the quick focus brings it into focus 3 times faster than the fine focus, in just a few smooth revolutions. This allows you to quickly acquire focus on a moving target. Once the subject is in approximate focus, the fine-focus knob provides fingertip control for achieving critical sharpness, essential for resolving minute details at high magnification or for digiscoping.

Chassis & Weatherproofing: A 3.21 lb Magnesium Alloy Body

The PROMINAR TSN-88A's body is constructed from a 100% magnesium alloy. Kowa says this makes it tougher and lighter than its predecessor; the scope body weighs 3.21 lb. The shell is fully waterproof and nitrogen sealed, which guards against internal fogging.

• KR Coating: The exterior surface of the 88mm objective lens is treated with Kowa's proprietary KR coating, which repels dirt, moisture and dust from building on the surface.
• Sliding Sunshade: An integrated, twist-out sunshade protects the objective from rain and stray light, enhancing image contrast. It also features a built-in aiming sight to help you quickly locate subjects.
• Dual Tripod Mount: The tripod mount has a removable screw: inserted, it fits 1/4-inch tripod heads; removed, it fits 3/8-inch heads.

Digiscoping Capabilities: Ultra-Telephoto Photography

Kowa calls the TSN-88 PROMINAR the king of digiscoping (taking photos through the spotting scope's eyepiece) and lists this kit as ideal for digiscoping with a camera or smartphone. The scope body has an accessory collar for attaching Kowa digiscoping adapters for DSLR and mirrorless cameras, such as the TSN-PA7 and TSN-DA10, used with the TE-11WZ II eyepiece.

Kowa says the improved coatings further enhance digiscoping performance even at the highest magnifications, producing images that were once only achievable with high end DSLR systems, and offering ultra long range telephoto options not possible in conventional photography.

Filters & Protection: The 95mm Objective Thread

The front of the TSN-88A's housing features a 95mm filter thread, which lets various types of filters be attached to the scope.

Kowa offers the optional TP-95FT protection filter, made for the TSN-99 and TSN-88 PROMINAR scopes. It carries Kowa KR coating to repel dirt and moisture and helps protect the objective lens from harsh environments. Kowa also makes the C-88A-N neoprene case for the TSN-88A.

Vanguard VEO 5 Tripod: A 17.6 lb Capacity Carbon Fiber Support System

This kit includes the Vanguard VEO 5 264CV14, a full-sized carbon fiber tripod that Kowa recommends for its larger TSN-88 and TSN-99 PROMINAR models. Vanguard gives a carry weight of approximately 4 lbs and a load capacity of up to 17.6 lbs, suitable for spotting scopes, DSLR and mirrorless cameras, or hybrid setups. Its 26mm diameter carbon fiber legs provide excellent rigidity to minimize vibrations at high magnification.

The tripod is topped with a VEO PV-14 fluid 2-way video head, whose counterbalancing spring assist helps smooth out tilting movements. A long pan handle and independent pan/tilt locks give controlled operation. The tripod has three adjustable leg angles (23°, 50°, 80°), rubber feet that convert to built-in spikes for secure footing on rock, dirt or soft ground, a hexagonal center column that converts to a short column for low-angle use down to approximately 8.5 in, and an Arca-compatible QS-71P quick-release plate.

Field Maintenance: Care and Cleaning for the TSN-88A

Proper care is essential to maintaining the optical performance of your PROMINAR scope. For the lenses, always remove loose dust and grit first using a blower brush or compressed air. Then, gently clean the lens with a light circular motion using an optics cleaning cloth, gauze or cleaning paper. Commercial lens cleaners can leave a film, so use only the smallest possible amounts.

Clean the body with a blower and a clean, soft cloth, never with solvents such as acetone, benzene or thinner. For moving parts like the focus wheels and sunshade, use a soft brush to clear away any debris. After use in damp or coastal environments, it is critical to thoroughly clean and dry the scope at room temperature before storage, since storing it uncleaned can lead to stains and mold. Store the scope in a dry place with the lens cap off, and for long periods in an airtight container with desiccant.
