EXPLORE SCIENTIFIC 68° Ar Eyepiece 16mm (1,25")

The neutral density filter transmits light uniformly across the entire visual spectrum. It serves as an excellent filter to reduce glare and irradiation when observing the Moon with any telescope 4"(10.2cm) and larger. The ND96 filter may also be employed in the splitting of close double stars where one of the binary pair significantly exceeds the other in brightness. Very flat design, with only 5.0mm light path. FEATURESreduces brightness for a higher contrastideal for observing the mooncan be combined with other colour filtersvery flat design, with only 5.0mm light path SCOPE OF DELIVERY 1x Color Filter #ND96 Moon Filter (0.9 density; 13% transmission)

High power eyepieces (e.g. 3mm to 10mm) are used not only for obvious observations of planets and double stars, but can be employed for bright, compact deep sky objects. Not only will the scale of an object like a planetary nebula or globular cluster be impressive as it fills the eyepiece FOV, but the background sky will be very dark as the contrast effect increases with added magnification, provided that the atmospheric seeing conditions are favorable enough to reveal a sharp image. The 6.5mm is a popular choice for a wide variety of telescopes, producing some of the highest magnification views that most astronomers will observe at.Comfort, Quality, Value. The Explore Scientific 52° LER Series Most short 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

This dovetail rail is suitable for mounting on BRESSER MESSIER 6 , 8 and 10 inch Dobson telescopes. The dovetail rail is manufactured according to the GP standard and therefore these Dobson telescope tubes can be used on any telescope mounting with the appropriate carrying capacity. The prism rail is 200mm long and therefore offers sufficient clearance for secure mounting on the telescope mount. In combination with the optionally available carrying handle Art. No. 4940150, these Dobson telescope tubes can also be easily transported because the carrying handle is mounted in the centre of gravity of the telescope. This dovetail rail is also suitable as spare part for all other MESSIER telescopes with 200mm dovetail rail.

​The BRESSER EQ-3 is a German equatorial telescope mount that can be used universally for light to medium-weight telescope tubes with a net weight of up to 5 kg.The only requirement for telescope tube mounting is a universal Vixen profile GP dovetail mounting bar - found on many commercially available telescope. This high-quality equatorial mount allows easy alignment to the celestial pole in no time and then allows tracking of all celestial objects manually with its single RA axis. Both RA and DEC axes come with manual slow motion control cables, for easy adjustment of your telescope's pointing.  Also included is a sturdy, yet lightweight, aluminium field tripod, which can be individually adjusted in leg height to give you perfect stability, even on rough ground. The included 1.5 kg counterweight is used to adjust the balance between the telescope tube and the mount.  Further counterweights can be supplied if needed. NOTE: If you want automatic Right Ascension tracking of celestial targets, this telescope mount can be equipped with the optional motor set Art. 4951400.FEATURESGerman equatorial telescope mountFor light to medium-weight telescope tubes of up to 5 kg net weightUniversal Vixen GP-style dovetail holderEasy polar alignment with adjustable altitude and azimuth axesAllows convenient tracking by slow motion right ascension axisWhat's IncludedBRESSER EQ-3 mountField tripodCounterweight
