Bresser Pollux 150/1400 EQ Reflecting Telescope

The distance from the optical center of a lens to its image plane when the lens is set at its working focus, expressed in a standard length unit such as millimetres or centimetres. It indicates the angle of view and zoom capability of an optical system and helps users compare lenses with different fixed focal lengths.

The distance between the optical center of a lens and its image plane, expressed in millimetres. It can be a single value for fixed‑focal lenses or a range indicating the minimum and maximum focal lengths covered by zoom optics. This measurement helps users understand the field of view and zoom capability of cameras, lenses, and other optical devices.

The optical magnification factor of a device such as a camera lens, binoculars or telescope. It indicates how many times larger an object appears compared to its actual size when viewed through the product. Values are expressed as a multiplier (e.g., 2x, 10x).

The type of mechanical attachment used to secure the product, such as pushpins, steel rods, screws, or other mounting hardware. It indicates how the item is intended to be mounted on a surface or frame and helps users determine compatibility with their installation setup.

The linear measurement across the widest part of a telescope’s objective lens, expressed in units such as millimeters or centimeters. It indicates the size of the primary optical element and determines light‑gathering capability and image quality.

The overall linear dimension of a product measured along one axis, expressed with a standard unit such as meters, centimeters or inches. It represents the full size from end to end and is used to compare physical dimensions across similar items.

Indicates whether a tripod is supplied with the product as part of its standard package. A value of "Yes" means a tripod is included and ready for use; a value of "No" means no tripod is provided and must be purchased separately.
