Loved by deep sky observers, a 30mm focal length eyepiece produces a large exit pupil which floods your dilated eye with light, which is needed to see faint galaxies and nebulae. Low power eyepieces are very important to observers for a variety of reasons: Their wide true field of view make object location and pointing far easier. Many deep sky objects are large and are best viewed at the lowest magnifications your telescope/eyepiece combination can achieve. When seeing conditions are poor, objects will often still look sharp at low powers.Comfort, Quality, Value. The Explore Scientific 52° LER Series mid-range focal length eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 52 degrees, these eyepieces offer incredible value in a very nice eyepiece. Expect exceptional quality and value versus a comparably priced Plossl.  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 patented EMD"-coating produces high contrast images and prevents 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.SPECIFICATIONS:Large eye distance, large field and great image sharpnessExcellent viewing position for people with glassesExcellent field sharpness even with fast optics52° apparent field of viewArgon-purging prevents internal fogging, the sealing facilitates cleaningPatented EMD"-coating to maximize contrastBlackened lens edges to avoid reflexesAll eyepieces of this series are parfocalStainless steel barrel with conical security cutoffDust covers and protective bag includedSCOPE OF DELIVERY:52° EyepieceDust coversProtective bag

Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

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)

NEW – now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.In the past few years the Bresser Newton telescopes have become the standard workhorse for Deep Sky astrophotography. We now proudly present the second generation of this telescope, the Bresser NT-203s/800 with Hexafoc and fast parabolic main mirror. The Bresser NT-203s/800 f3.9 will deliver you deeper images due to its - compared to 8" f/5 systems - oversized primary mirror and therefore faster optical system with the same exposure time. The big 85 mm secondary prevents vignetting for optimal illumination The excellent 2,5" Hexafoc focuser also does not cause vignetting due to its large diameter and makes focussing a joy - the smoothness and shifting-free operation sets new standards in this price class. This groundbreaking focuser, tube rings with 44mm universal standard dovetail and camera mounting feature and a high-end finderscope with haircross and laser-engraved scale  leave nothing to desire even for demanding astrophotographers. The NT-203s/800 Hexafoc has a classical tube construction with an aluminium tube. The focuser can be upgraded with a 10:1 reduction (part No. 0625720) without problems. Also prepared for use with the HR Coma Corrector (part No. 0510330) which eliminates coma, field-curvature and astigmatism.Mount and Tripod. The BRESSER EXOS 2 is a rugged mount with high rigidity and precision tracking for visual observation and astrophotography. The tripod is extremely rigid to suppress vibrations really well. This model is very well machined and has an illuminated polar finder scope and precise graduated circles. A powered twoaxis control (BRESSER Exos Duo) or a GoTo-Kit is available as an optional extra. The BRESSER EXOS 2 can take the weight - depending on length and use of up to 13 kg. This allows you to use refractors of up to 152 mm aperture and mirror telescopes of up to 203 mm aperture.Please note: Reflector telescopes with optical design Newton are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing.CHARCTERISTICS OPTICS Optical design: reflector telescopeMirror diameter: 203mm / focal length: 800mm / F/3.9Maximum recommended magnification: 406xTelescope for night and solar observing Very high quality Hexafoc focuser with 2.5" free inner diameter Diffraction limited optics with parabolic main mirror 8x50 straight through viewfinder with reticle Optimized finder socket for comfortable use Cradle rings with handle and integrated piggyback camera holder (1/4 thread) Smartphone adapter for celestial navigation included Dovetail plate with stainless steel rail Can be connected to SLR cameras (optional T2 ring required) 50.8mm (2) to 31.7mm (1,25) adapter with integrated T2 thread (T2-adapter ring for your camera is needed) Backfocus fully inward focused: 60mm 85mm secondary mirror for optimal illumination Large knobs for primary and secondary mirror adjustment Tube without accessories: 8.7 kg - Tube with all accessories mounted: 11.5 kgCHARACTERISTICS MOUNT Stable parallactic mount with fine drive in both axes Ball bearings in both axes for more precise movements Stable height adjustable stainless steel tripod ( Min. 69cm / Max. 109.5cm ) Load capacity up to 13 kg payload Retrofittable with the Bresser Star Tracker Goto Kit ( item no. 4951750 ) Circular bubble for easy horizontal alignment Pole height scale for setting the latitude Scaled graduated circular rings to facilitate finding objects using a star atlas or planetarium software Pole finder scope with optional illumination ( item no. 4964212 ) Tripod weight: 4.7 kg Mount weight: 5.6 kg (without counterweight) Total weight incl. counterweight: 19.3 kg Batteries: not includedSCOPE OF DELIVERY Optical tube 26mm Super Plössl eyepiece (31.7mm / 1.25") Integrated 31.7 mm and T2 adapter Prism rail with stainless steel clamping surface Adapter for 50.8 mm (2") eyepieces 8x50 optical viewfinder Rotatable star map Aperture solar filter Tube clamp with handle and camera holder Smartphone adapter for celestial navigation Adjustable polar finder scope with optional illumination Astronomy PC software Stellarium (via download) BRESSER EXOS-2 mount Stainless steel tube field tripod with accessory tray 2 x 4.5 kg counterweight
