EXPLORE SCIENTIFIC 68° Ar Eyepiece 40mm (2")

The Twilight I is a light-to-medium-duty alt-azimuth mount and tripod designed to quickly and easily accept small to medium sized refractors, such as the AR102 + AR127s or ED102mm + ED127, and of course, the ED80mm. Lightweight, fast Newtonians will also match up nicely with the Explore Scientific Twilight I mount. As long as your telescope does not exceed 18 pounds and has a Vixen-Style Universal Dovetail bar for mounting the telescope to the mount head, you are good to go. The Twilight I alt-azimuth mount head is made of powder-coated aluminum and there are worm gears on both axes. The adjustable angle head can be tilted forward or back at a 45° angle to allow more clearance for your telescope so you can point it straight up for viewing at the zenith. The Allen hex wrench for doing the mount head adjustment can be safely stored at the integrated magnetic holder.  Slow-motion control cables are attached on the vertical and horizontal axes, and are easy to turn during the night, even with gloves on, due to the over-sized knurled knobs that are attached to the end of each cable. They can be attached to either side of each axis to accommodate right or left-handed users, or different types of telescopes (e.g. refractors vs. Newtonian reflectors) for ease of adjustment. The stainless steel tripod that comes standard with the Twilight I mount has adjustable legs and a wide foot print of 42 inches, which makes the tripod more stable. A spreader bar locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum. SCOPE OF DELIVERTwilight I Telescope MountStainless Steel Field tripod

The "Wow-effect" eyepiece: You see deep sky objects as if you were in space! It makes you forget that you are looking through a telescope. This makes up for an unforgettable observing experience, that even exceeds the expectations of demanding amateur astronomers. Of course it has the same specifications as the already well established 100° eyepieces: inert gas purged, and waterprrof, the high end EMD coatings are protected from the outdoors.  Dust, fungus, humidity and cleaning solutions cannot harm the precious eyepiece for years of observing to come!

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)

One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lighting, such as street lights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar system enormously. Depending on the type of celestial object, it is possible to increase the contrast dramatically by blocking the interfering artificial light. The EXPLORE SCIENTIFIC O-III filteruses a characteristic property of the so-called emission nebulae. Those objects glow in special colours, the so-called emission lines. Those emission lines are linked to chemical elements - in this case, oxygen. The EXPLORE SCIENTIFIC O-III nebula filterblocks all other colours (and thereby nearly all the artificial light) and only the two emission lines of the oxygen can pass the filter. The result is astonishing: suddenly, nebulae are visible in locations that were completely empty without using filters. In suburban skies, for example, the veil nebula NGC 6992 is almost invisible with a 200 mm telescope. By using this filter, you can see the nebula and its structures without any difficulties. A must for every visual observer and for astrophotography. The EXPLORE SCIENTIFIC nebula filterscome with an individual test certificate - your guarantee for receiving a premium filter. This filter's narrow passband of only 6.5 nm bandwidth highlights the faint emission nebulae or makes them visible even under difficult urban conditions. FEATURES enables the observation of so-called emmission nebulae blocks almost the entire artificial light only the two emmission lines of the oxygen passes the filter band pass width: 6.5 nm narrow band version for difficult urban conditions allows more contrast for faint deep sky objects ideal for use near cities, in heavy brightened skies individual test certificate included to guarantee you receive a premium filter SCOPE OF DELIVERY 1x 2'' O-III nebula filter

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.

If a observing session is a relaxing and joyful experience is heavily dependend on the choice of eyepieces. People wearing glasses very often have the problem to see the entire field of view when they are using eyepieces with large apparent fields. This problem is now history. The new 92°- LER eyepieces by Explore Scientific do not only offer excellent image sharpness and high resolution and contrast over the enourmous full field of view - you can see that full field without problems even with glasses on. Fatigue due to tense head positioning and strained viewing simply does not happen because of the excellent viewing comfort these eyepieces provide even to observers wearing glasses. Enjoy the unique combination of excellent image sharpness out to the edge of the field even for fast optics, superior contrast and unmatched viewing comfort. Eyepieces with perfect combinations of various modern glass substrates and highest standards in manufacturing, quality control and service are a tradition at Explore Scientific Tradition - the outstanding resolution and sharpness to the very edge equal that of our eyepieces of the 100° line.These eyepieces are the choice for observers wearing glasses - with excellent performance and durability. The rubber inlet and the foldable eyecups make handling and using in the field easy. The patentet EMD"-coating teams up together with internal baffles to produce high contrast images and to prevent reflexes and ghosting.The argon purging effectively prevents internal fogging, and you don´t have to deal with dirt, fungus or cleansing fluids getting between the lenses.The eyepieces are sealed - this makes sure you will be able to enjoy these eyepieces for many years to come.
