EXPLORE SCIENTIFIC 120° Ar Eyepiece 9mm (2")

With teleextenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for the observation of the moon, the planets or small Deep-Sky objects with the same eyepieces. So you can use the advantages of eyepieces with longer focal length - such as the bigger eye distance and the more relaxed observing comfort - at high magnifications also.These teleextenders incorporate a telecentric optical design that deliveres a excellent image sharpness over the whole field of view and are premium choices for visual observations and astrophotography. The combination of excellent fully multicoating with superior optical design makes the Focal Extenders superior to classic Barlow lenses.FEATURES: Suitable for visual observations and astrophotographyDoubling the effective total focal length of the telescopeFour lens telecentric design Fully multicoatedFilter thread for color or nebula filtersSCOPE OF DELIVERY: Fokal Extender 2 x Adapter 2" (50,8mm) auf 1,25" (31,7mm)

Are you having trouble focusing your eyepiece or camera? Then use this 37.5 mm extension sleeve to increase the distance between the 2.5 inch HEXAFOC eyepiece extension and the eyepiece or camera. The extension sleeve has an M68x0.75 mm internal and external thread and can therefore be screwed directly onto the HEXAFOC draw tube.

NOTE: The built-in infrared light is not suitable for military applications. Many animals are nocturnal, and don't venture out until well after dark. The BRESSER Explorer 200RF digital binocular night vision device allows you to view deer, wild boar and other animals in complete darkness. It features an 850 nm infrared light, which functions as an invisible light source, as well as a built-in rangefinder so that you can determine the exact distance to your target. Magnification The night vision device features 6x optimal magnification and a 3x digital zoom, allowing you to view objects at up to 18x magnification. Range The Explorer 200RF night vision device is also suitable for daytime use. Thanks to the comfortable binocular eyepiece, you can observe from a distance of up to 200 metres at night and up to 500 metres during the day. The rangefinder functions at distances of up to 200 metres. Recording function The BRESSER night vision device features a recording function, which allows you to capture images and Full HD videos of your observations and view them on the built-in 7.6 cm (3'') TFT display. It also comes with an automatic IR cut filter, which produces true-colour images during daylight. Battery life The Explorer 200 RF is ideal for long observation sessions - the two li-ion batteries last for up to 10 hours during the day and up to 6 hours in night vision mode. FEATURES Designed for civilian use only Digital night vision device with rangefinder Ideal for hunting, camping, nature observations, etc. Optical magnification: 6x Digital zoom: up to 3x Max. magnification: 18x Visual range: 200 m at night, 500 m during the day Rangefinder range: up to 200 m, up to 64 m for animals with light-coloured skin Automatic IR cut filter for true-colour images during the day Aperture: f/5.5 during the day, f/1.3 at night Field of view at a distance of 1000 m: 175 m (10°) Recording function for photos and videos Storage medium: microSD card 4 to 64 GB (not included) Battery life: up to 10 hours in daylight mode, up to 6 hours in night vision mode 7.6 cm (3'') TFT display Display resolution: 360*640 Illumination: 850 nm infrared LED Power supply: 2x replaceable 18650 li-ion batteries (recommended capacity of 3000 mAh or higher) (included) PACKAGE CONTENTS Night vision device USB cable Carry strap Premium transport case 2x li-ion rechargeable batteries Cleaning cloth Instruction manual

These eyepieces with their huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods. These ultra-wide angle eyepieces played a critical role in the military for aiming at targets, and their long eye-relief counterparts helped reduce eye injury from recoil.Each 100° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus. This also maximizes the life of the internal coatings.To make sure, every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes. All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

After three years of testing and refining we are extremely proud to present the new Explore Scientific High Resolution (HR) Coma Corrector. This corrector is a class of it´s own - it is fully functional for visual use and expands the focal length by only 6%! The Explore Scientific Coma Correktor is delivered as a complete set together with a rotating helical focuser with laser-etched scale, so you get a full package: corrector, adaptor to T2 (M42x0.75mm), adaptor to M48 (M48x0.75) and the helical focuser for visual fun. This coma corrector really is "high resolution" - it deliveres a visual polystrehl performance of 0,98 at f/4 and 0,96 at f/3! So it can stay in the telescope - and you will not only enjoy a tack-sharp Jupiter, but aslo sharp and defined moons in the future! What this means in terms of performance is shown in the three pictures with the graphs - the sharpness increase in those comparisons with and without corrector are stunning (examples are 400mm f/4, f/3,5 and f/3). Please notice: These graphs are for FLAT FIELD! You will get this performance without refocussing! Diameter of the field is 30mm - it doesn´t make sense to increase this with 2" and fast optical systems. Length of the 2" corrector barrel is approx. 85mm and it can be used with almost all 2" focusers on the market. To use the HR Coma Corrector visually, you need to have at least 32mm spare inward travel at your focuser, while the focus is on the same plane as the focusers end. Photographically there is no problem - the HR Coma Corrector shifts the focus outward by about 35mm, so that you will have no problem in achieving focus, when you are able to focus your camera without the HR Coma Corrector.
