More on the way
Built to stay out longer.
The AT Endura 21–65×75 combines premium HD optics, a versatile integrated zoom and a bright 75 mm objective in a rugged 1,510 g angled spotting scope made for long-range observation.
AT Endura 21–65x75
From a wide overview to decisive detail.
Long-distance observation is about more than finding a subject. The AT Endura helps separate fine structure from complex backgrounds, preserve natural colour and reveal the details needed to identify wildlife, judge game and interpret movement with confidence.
21–65× variable magnification
Acquire subjects quickly at lower power, then move smoothly into higher magnification without changing an eyepiece.
75 mm HD objective
The large objective and 90% light transmission support bright, high-contrast viewing in shadow, changeable weather and fading light.
Controlled field of view
See 33 m at 1,000 m on 21× for efficient scanning, narrowing to 18 m at 1,000 m on 65× for precise inspection.
Premium lightness
At approximately 1,510 g, the carefully balanced body is made for longer carries, repeated relocations and extended sessions behind the glass.
Stay with the moment longer.
An angled eyepiece supports comfortable viewing at varied subject heights.
Built for long sessions in reserves, wetlands and woodland edges.
A premium scope that remains approachable from the first outing.
Light enough to carry between viewpoints throughout the day.
A steady, shared view for patient observation.
Wide-area scanning and distant identification from one integrated optical system.
Recognise plumage, proportions, movement and behaviour with greater confidence.
Straightforward controls keep attention on the observation.
One zoom range. Two essential perspectives.
At 21×, the AT Endura shows a 33 m-wide section at 1,000 m, helping you scan terrain and acquire a subject. At 65×, that visible width narrows to 18 m, placing more of the view on fine structure and identification detail.
The integrated zoom ring moves continuously through the range, so the transition remains fast, intuitive and uninterrupted.
Detail that remains natural.
Proven Swarovski HD optics deliver image sharpness, controlled contrast and natural colour reproduction. Fine edges, subtle tonal differences and subject contours remain easier to interpret across the zoom range.
The 75 mm objective gathers the light needed for demanding observation, while 90% transmission supports a bright, high-contrast view at dawn, dusk and in deep shadow.
Premium lightness for longer days.
A deliberately non-modular design keeps the complete optical system straightforward and lowers overall weight. At approximately 1,510 g, the AT Endura is practical for long approaches, repeated repositioning and extended field sessions.
The integrated 21–65× eyepiece is always ready—there is no separate eyepiece to carry, fit or change in the field.
Clarity when conditions turn against you.
Changing temperatures, moisture, wind, deep shadow and long hours behind the glass are part of real observation. The AT Endura pairs a rugged rubber-armoured body with inert-gas filling, a −20 to +50 °C functional range and 4 m submersion tightness.
A broad, textured focusing ring remains easy to control in the field.
Long-range assessment from a compact, focused optical system.
Sealed construction for weather that refuses to cooperate.
Made to travel through cover, moisture and changing terrain.
Rubber armour adds grip and field protection.
High light transmission supports useful detail as the day fades.
Stay behind the glass when distant movement demands patience.
See the structure of the landscape—and what moves within it.
Designed around long observation.
Everything has a purpose.
The focused layout puts the controls used most often directly under your hands, while the rotatable tripod collar lets the angled eyepiece adapt to different observing positions.

Ready quickly. Adjusted precisely.
The manual reduces operation to a small number of direct movements: set the eyecup, focus, choose magnification and rotate the scope to a comfortable viewing position.
Remove the protective covers
Release the objective cover and rotate the eyepiece cover clear before observation.
Set the eyecup
Turn the eyecup fully in for use with eyeglasses, or fully out when viewing without eyeglasses.
Focus from near to far
Turn the focusing ring clockwise for distant subjects and counterclockwise for nearer subjects.
Move through 21–65×
Turn the magnification ring clockwise to increase power and counterclockwise to decrease it.
Rotate the viewing angle
Loosen the locking screw, rotate the body within the tripod ring, then retighten it at the preferred angle.
Mount to a tripod head
The foot fits Swarovski PTH and CTH heads directly. Its 3/8″ UNC thread includes an installed reducer for 1/4″ UNC heads.
Tripod and digiscoping ready.
