A very compact, complete telescope for observing the sun in H-alpha light.The LS50THa solar telescope offers 50 mm free aperture, 350 mm focal length, and provides a bandwidth of <0.75 Angstrom. The telescope is fitted as standard with the air-pressure tuning system "Pressure-Tuner", the Etalon is safely installed inside the telescope. Prominences and surface detail can quickly be viewed spontaneously. This very portable system is an ideal travel companion for wherever you go.A B400 blocking filter is installed inside the star diagonal. The B400 is good for visual observing. Focusing is achieved by a non-roting Helical focuser.Please note that there is only a small back-focus at this telescope, therefore solar-imaging is very difficult. The LS50THa is designed for visual solar observing. We recommend for imaging the 60mm telescopes of the LS60MT series.Also double-stacking with a bandwidth of only <0.5 Angstrom is possible by using the additional available LS50C filter (0550210). This filter threads directly onto the LS50THa telescope. Double-stacking will provide much more contrast, and more details on the sun will become visible.FEATURESAperture: 50  mmFocal Length: 350 mmBandwidth: <0.75 AngstromTuning: air-pressure tuning system "Pressure-Tuner"Blocking Filter: B400non-rotating Helical focuserTube-ring with 1/4-20 tapped base (standard thread for photo-tripods)Length: 37cmWeight: 2.1kgSCOPE OF DELIVERYLS50THa H-alpha Solar TelescopeB400 Blocking Filter in star-diagonalPressure-TunerTube ring with 1/4-20 connection for mounting on photo-tripodsnon-rotating Helical focuserInstruction manual

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)

Adapter T2 to 2", takes for example 2" eyepieces to Lunt Solar Systems blocking-filters.This adapter offers a T2 female thread at the telescope-side, and a 2" connection at the eyepiece-side.For example you want to use your 2" eyepieces at Lunt Solar Systems telescopes or filters? All you need is this adapter. Simply remove the 1.25" eyepiece tube from your blocking-filter, and thread on this 2" adapter. It takes T2 threading to a 2" eyepiece tube.You can use 2" eyepieces with this adapter at:• LUNT H-alpha telescopes (not at LS35THa!)• the blocking-filters of LUNT H-alpha filter systems• LUNT Ca-K modules• all telescopes/adapter with T2 male threadTechnical data:• Thread at telescope-side: T2 female thread• Eyepiece connection: 2"Delivered by order:• Adapter T2 to 2"(Blocking Filter not included)

This adapter replaces the M42x0.75 Adapter for CCD Camera that comes standard with the EXPLORE SCIENTIFIC 3-inch Field Flattener/0.7x Focal Reducer. Allows the connection of a camera via M48x0.75 thread. The larger free inner diameter than T2/M42 effectively prevents vignetting when using a full format camera. The illumination of the camera sensor is therefore optimised.FEATURESAllows the connection of a camera via M48x0.75 threadLarger free inner diameter than T2/M42No vignetting by using cameras with full frame sensor Fits to EXPLORE SCIENTIFIC 3" Flattener 0.7 x ReducerMade of black anodized aluminumSCOPE OF DELIVERYAdapter with M48x0,75 thread

When cleaning high quality optical lenses, you have to be very careful. After all, it would be very annoying to successfully remove the dust but leave a scratch behind. With the BRESSER BR-LP10 lens cleaning pen you can safely clean optical and coated glass. With the brush on one side you can remove coarser dirt before polishing the lenses with the other side. FEATURES lens cleaning pencil for safe cleaning of optical and coated glass brush to remove dust on one sidepolishing pad on the other side SCOPE OF DELIVERY 1x lens cleaning pencil

BRESSER 30mm Plössl Eyepiece 1,25" (31,7mm) Since years a well known and approved Plössl eyepiece. Ideal to improve the performance of your telescopes for a low budget price. All the BRESSER Plössl eyepieces provide sharp and high-contrast images because of the 4-lens design. All lenses have fully-multicoated surfaces which prevents reflections efficiently. Every eyepiece is equipped with a foldable rubber eyecup to avoid straylight from the sides and the inner eyepiece shaft is carefully blackened as well. Housing and eyepiece shaft are completely made from metal - no plastic is used. Filter thread for use with colour- and nebular filters is also available. All these Plössl eyepieces offer a much better image quality than all the very simple made Kellner and Huygens eyepieces. FEATURES Focal length: 30 mm Field of view: 50° Lens-Design: 4 lenses in 2 groups , fully-multicoated Housing material: completely made from metal Rubber eyecup: YES, foldable Filter thread: YES Storage: Twist-pack SCOPE OF DELIVERY BRESSER Plössl eyepiece with rubber eyecup Twist-pack
