Nicholas 10-30x25 Telescope Black – Adjustable Zoom Monocular for Travel and Outdoor Use

This Nicholas telescope gives you smooth zoom control from 10x to 30x, so you can adjust the view to suit landscapes, wildlife, or close-up exhibits. Its 25mm objective lens and BAK4 prism work with multi-layer broadband green coating to deliver clear, well-lit images. The body is made from imported aluminium alloy with metal internal parts and elastic rubber sections for a reliable, comfortable hold. Compact enough to slip into a bag, it measures 127mm when collapsed and extends to 200mm, with a slender 32mm diameter that fits comfortably in your hand.
Features and Construction

Every part of this monocular is chosen for practical, everyday use. The adjustable zoom, close focus ability, and tripod port make it a flexible companion for both far and near viewing tasks.
Adjustable Zoom Range
Magnification moves from 10x to 30x in a continuous range. At 10x the field of view is 3.5°, narrowing to 2.0° at 30x. This lets you quickly shift from a wide panoramic scene to a close-up detail without changing equipment.
Close Focus Performance
A minimum focal distance of 0.5m sets this telescope apart. You can examine small objects, artwork, or exhibits at very close range, which is useful in museums, galleries, or during practical inspections where space is limited.
Optics and Coatings
The BAK4 prism and multi-layer broadband green coating on the lenses reduce internal light loss and reflections. This combination helps maintain brightness and contrast across the zoom range, especially in variable outdoor lighting conditions.
Build and Materials

Durability comes from the aluminium alloy body and metal internals, while the rubberised outer sections provide a non-slip grip. The compact design supports easy one-handed operation.
Imported Aluminium Alloy Body
The main structure uses imported aluminium alloy, which keeps the telescope light yet rigid. Metal parts inside the lens body add to the overall strength, ensuring the zoom mechanism remains smooth over time.
Elastic Rubber Sections
Strategic rubber elements on the exterior improve handling in damp or cold conditions. They also provide a small amount of shock absorption if the telescope is knocked or dropped.
Size and Portability
With collapsed dimensions of 127mm x 32mm x 32mm, the telescope fits into most jacket pockets or small pouches. Extended length is 200mm, still slim enough to pack easily. The 25mm objective lens keeps the front diameter compact.
Uses and Placement

This monocular is designed for travel, outdoor sports, birdwatching, and exhibition visits. Its 0.5m close focus also makes it useful for hobbyists inspecting coins, stamps, or small mechanical items.
Travel and Outdoor Sports
Light weight and small collapsed length mean you can carry it on hikes, city tours, or sporting events. The tripod thread allows stable long-range viewing without arm fatigue.
Exhibition and Museum Viewing
Up-close exhibits often have fine details that are hard to see with the naked eye. The 0.5m focal distance lets you study paintings, artefacts, or models from a comfortable distance without triggering alarms or barriers.
Everyday Carry and Quick Viewing
The simple stretch-or-rotate focus system means you can bring the image into sharp view in seconds. No complex adjustments are needed, making it suitable for spontaneous looks at birds, landmarks, or street scenes.
Benefits and Buying Value

This telescope gives you adjustable magnification, close-focus capability, and a solid metal build at a sensible size. It avoids unnecessary extras while concentrating on core viewing performance.
Versatile Magnification
Having 10x to 30x in one unit saves you from carrying multiple lenses or binoculars. You can use lower power for walking and scanning, then zoom in for static observation.
Practical Close Focus
Most telescopes cannot focus below 1–2 metres. The 0.5m capability here expands what you can examine without requiring a separate macro device or closer approach.
Why Choose This Model
If you need a single, portable optic that handles both distant views and close inspection, this Nicholas model delivers those capabilities without bulk. The metal-and-rubber construction suits regular outdoor use, and the tripod compatibility adds stability when you need it most.
