EXPLORE SCIENTIFIC 82° Ar Eyepiece 24mm (2")

This Barlow lens doubles the focal length of your telescope. It allows you to make astronomical observations with a higher magnification than a conventional eyepiece. Thanks to the Barlow lens between the eyepiece, you can obtain a greater magnification whilst maintaining a comfortable interpupillary distance.This Vixen 2x Barlow lens is ideal for observing and photographing lunar landscapes and details on the brighter planets. The Barlow lens also features a T2 connection for photography with DSLR cameras. With T2 extension tubes, it can also be used as a camera projection adapter.With a deflecting prism, the Barlow lens enables you to obtain a magnification factor of 3.3x.FEATURES2x Barlow lenses with T2 thread2-lens optical systemDoubles the magnification factorAlso suitable as a camera adapter31.7 mm sleeveWeight: 80 gDELIVERY CONTENT 2x Barlow lenses Dust caps

With the introduction of the 68° Series we are pleased to make two important improvements in eyepiece manufacture, the first being 15 layer Enhanced Multi-layer Deposition (EMD™) coatings on all glass-to-air surfaces to gain maximum contrast, and waterproofing the eyepiece with the use of Argon gas purging instead of standard Nitrogen gas. Although Nitrogen is a fine choice that will last for many years, Argon is a larger molecule that maintains its protective properties over a wider range of temperatures, and is even more resistant to diffusion thereby further extending the protective waterproof environment of the eyepiece body. Through computer-optimized design, a careful selection of optical glasses, and enhanced multi-layer deposition coatings, the Explore Scientific 68° Series™ eyepieces produce long eye-relief and ensure high image-correction, a flat field, and high contrast across the entire image field. An excellent choice for those who make extended visual studies of detail with subtle variations of brightness, and for those who must wear glasses while observing. All 68° Series eyepieces are fully EMD (Enhanced Multi-Layer Deposition) coated and edge-blackened to produce superior contrast.

THE PMC-EIGHT GOTO SYSTEM JUST AWARDED A SKY AND TELESCOPE HOT PRODUCT FOR 2018. The Explore Scientific EXOS2-GT with PMC-8 Electronics is quite unique and special. Most of the serious amateur mounts on the market today offer single processors. The PMC-8 electronics are extremely robust. They include a 2-Channel Multi-Processor Micro-controller with 8 CPUs that run independently and are completely deterministic in their behavior, thus the name PMC-8. Within this multi-processor system is a 64 Kbyte EEPROM Non-Volatile Memory bank used to store parameters; a Wireless Ethernet 10/100 with full IP function which permits operation from anywhere using a browser, ASCOM, or APP over the web or serial port; and Non-Volatile Memory used to store user selected parameters. The electronics also includes an Auto-Guide port (ST4 contact input) and features the only wireless ASCOM driver on the market. The belt driven system uses 2 timing pulleys (1-45 groove and 1-10 groove) with fiberglass re-enforced neoprene belt connected to a Nema11 bi-polar stepper .67 amps 12ncm motor then connected to the worm. Precise ball bearings in both axes ensures minimal backlash at all nine possible tracking speeds. The included battery pack (12 V) takes eight size "D" batteries. The head rests on a very tough and rigid stainless steel tripod with adjustable 2" legs from 26.8" to 42.5" and can support up to 28 lbs. of equipment. This system is all controlled from a tablet, notebook or desktop pc with 7" display and WIN8.1, WIN10+11, iOS or Android 4.4 with a beautiful full graphical user interface using our very own ExploreStars OpenGoto® Software. The ExploreStars OpenGoto® Software has the same basic functions as most all other mounts on the market today. ExploreStars is a free App downloadable from the Microsoft App store and GooglePlay. The basic download includes a standard 2 star or 3 star alignment procedure, over 70,000 star database, the Messier Catalog and Solar System objects. The software interface features a Classic four-button pattern for guiding, centering, moving and slewing on the touch screen of your tablet or phone. Pull-down menus open to offer the intuitive 2 star and 3 star alignment procedure, selection of the various catalogs, guided tours, the sync button, the park position, search feature and the coordinate input screen to enter RA and DEC coordinate information. Numerical key pad allows for selectable and user enterable GOTO speeds for slewing, centering and guiding rates. You can also set sidereal, king, lunar, solar, and user defined tracking rates. What makes this software different is that YOU can write your own code and import it into this software. Create a Messier challenge. Create a selectable list of objects you want to photograph and program that information into the software. With the ability to write your own code, you can create whatever your heart desires. Share it with the community of astronomers that are using this software. In addition, this mount can be controlled by any ASCOM compliant software using the built-in wireless ASCOM driver. GPS-compatible and auto time / date settings are dependent on optional receiver on computer, tablet or phone.Here are most of the ASCOM software packages available for use with the Explore Scientific / Losmandy G-11 with PMC-8 mount: ACP; APT; AST / ATC & Ricerca (Omega Lab); AstroArt; AstroMB; Cartes du Ciel / Sky Chart; CCD AutoPilot; DeepSky; Deepsky Planner; DFM Engineering; Earth Centered Universe Pro; EasySky; Eye and Telescope; Project Pluto; Hallo Northern Sky; Maxim DL; MaxPoint; PinPoint Astrometric; Prism; Sequence Generator Pro; Sidereal Technology; The Sky; SkyMap Software; SkyTools 3; Star Atlas PRO; Sky Observer; StarryNight; Stellarium; Virtual Moon Atlas; and WorldWide Telescope.VIDEO REVIEW:https://youtu.be/tmNPajsd9H4 IMPORTANT NOTE: To start using ExploreStars app, download the free app and download the celestial data set that contains the astronomical catalogs, reference images, and reference text.

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.FEATURESSuitable for visual observations and astrophotographyTriples the effective total focal length of the telescopeFour lens telecentric designFully multicoatedFilter thread for color or nebula filtersSCOPE OF DELIVERY Fokal Extender 3 x Adapter 2" (50,8mm) auf 1,25" (31,7mm)

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.
