Celestron HummingBird Spotting Scope 7-22x50 ED - Angled

The spotting scope with a compact design was developed for people looking for lightweight optical equipment for observing nature, landscapes, birds and distant objects in the field. Its small size and low weight of just 540 g make it easy to carry comfortably in a backpack or bag.

The model features an objective lens with a diameter of 50 mm and variable magnification ranging from 7 to 22x. The prism system uses BaK-4 glass, valued in optics for its bright image and even illumination across the entire surface.

The scope body is waterproof and nitrogen-filled. The use of gas reduces the risk of the optical elements fogging up on the inside during sudden temperature changes. This solution allows observation in conditions of increased humidity, during light precipitation and in colder times of the year. The housing features rubberised adjustment rings that improve magnification and focus adjustment. Their textured surface improves grip.

The design uses an objective lens made of low-dispersion ED glass. The material reduces chromatic aberration, the phenomenon of coloured fringing appearing along the edges of high-contrast objects. This results in more natural colour reproduction and a sharper image, especially when observing bird silhouettes, branches, buildings or landscapes against a bright sky.

The optical elements are coated with multilayer anti-reflective FMC (Fully Multi-Coated) coatings. The coatings reduce light reflections on lens surfaces, increasing light transmission and image contrast. Combined with the 50 mm objective lens and a twilight factor of 18.7, the design supports observation in lower light, for example in the morning, in the evening or on a cloudy day.

The eyepiece allows smooth magnification adjustment from 7 to 22x. The 7x setting provides a bright image, a wide perspective and makes handheld observation easier. The angular field of view ranges from 5.1 to 2.2 degrees, and the linear field of view at a distance of 1000 m falls within the range of 88.7-38.5 m. This solution makes it easier to track moving animals and observe wide areas.

At 22x magnification, more detailed observation of objects located farther from the observer is possible. The minimum focusing distance is 3 m, which also allows viewing objects located relatively close by.

The spotting scope stands out with its angled design, in which the eyepiece is positioned at an angle to the objective lens axis. This arrangement makes observation easier while sitting, standing or using a tripod, without the need to tilt the head excessively. It also works well when observing objects positioned higher up, such as birds in tree canopies.

The adjustable eyecup allows the eye position to be matched to the eyepiece. The eye relief is 15 mm, which makes comfortable observation easier also for people wearing corrective glasses - after properly adjusting the eyecup.

The spotting scope is equipped with standard eyepiece mounts with a diameter of 1.25". The included eyepiece can be replaced with a compatible astronomical eyepiece in the same standard. This makes it possible to match optical parameters such as magnification or field of view to the type of observation being carried out.

A 1/4" tripod thread is located on the bottom of the housing. It allows the spotting scope to be mounted on a tripod or monopod, which helps stabilise the image during observation at higher magnification. The lightweight design also allows the use of compact tripod accessories that do not excessively increase the weight of the equipment.
