Please contact our customer service if you would like to order this telescope.Complete H-alpha solar telescope with 300mm aperture and a bandwidth of <0.5 Angstroms. With Feather-Touch focuser, innovative air pressure tuning system and B3400 blocking filter.A extremely large telescope for observing the Sun in H-alpha wavelength, a precisely adjusted refractor with a free aperture of 300mm without central obstruction and 2128mm focal length. The telescope is equipped as standard with a double-stack system, two internal Etalon filters with the innovative air pressure tuning system Pressure-Tuner achieve a bandwidth of <0.5 Angstroms. The Pressure-Tuner system ensures a homogeneous H-alpha image and optimal performance. The Etalons are safely installed inside the telescope. The air pressure tuning system is precisely controlled by an electronic pressure tuner controller.Blocking Filter is the B3400. The B3400 is well suited for imaging the Sun. For visual observation we recommend an additional zenith mirror. The straight extension tube, in which the blocking filter is installed, is equipped as standard with a 2" eyepiece holder and also with an adapter for 1.25". Focusing is done by the legendary Feather-Touch focuser from Starlight-Intruments with 10:1 reduction.FEATURESAperture: 300mm (no central obstruction)Focal length: 2128mmBandwidth: 2 internal Etalons with <0.5 AngstromsTuning: Air-pressure tuning systemElectronic pressure tuner controllerBlocking filter: B3400 with 2" and 1.25" connectionFocuser: Feather-Touch focuser from Starlight-Instruments with 10:1 reductionDovetail bar with Losmandy level for astronomical mountsWeight: ?kgLength: ?cmSCOPE OF DELIVERYLS300THa Double-Stack H-alpha solar telescope2x Pressure-TunerElectronic pressure tuner controllerB3400 blocking filter in straight extension tubeFeather-Touch focuserDovetail bar (Losmandy level)Manual

This dovetail plate with 150mm length is suitable for Lunt Solar Systems LS50THa, LS60THa, LS60MT, and LS80THa telescopes.The width of the dovetail is conform to the GP-level standard. Therefore it could be used at the BRESSER EXOS 1+2 mounts for example, but also at many other mounts. The telescope connecting screws are 1/4-20 inch size and they do not look out of the rail, which makes this rail a perfect match for many astronomical mounts. The distance between the screws is matched for the Lunt Solar Systems telescopes LS50THa, LS60THa, LS60MT, and LS80THa.FEATURESLength: 150mmWidth: 44mmDistance between screws: 35mmScrews thread: 1/4"-20SCOPE OF DELIVERY1 x 150mm dovetail plate2 x 1/4"-20 screws

The BRESSER MyTime Jumbo LCD weather wall clock is the ideal weather wall clock for the office or other large rooms. With its 9 cm high numbers the time can easily be read even from a greater distance and from almost any position in the room. The setting of the time as well as the change to daylight saving time is done automatically via the DCF time signal (CET). Apart from that with the weather wall clock you can also always keep an eye on the temperature and humidity and you even get a weather forecast for the following 12 to 24 hours.  PLEASE NOTE: This device receives the DCF time signal (Central European Time). However, it also offers manual time setting in case it is used in a different time zone.FEATURESJumbo display 330 x 185mmRadio controlled clock (automatic setting of time and clock change) AlarmIndoor and outdoor temperature Indoor and outdoor humidity12-24 hours weather forecast Includes wall mounting and fold-out standSCOPE OF DELIVERY1x weather wall clock1x outdoor sensor1x manualREQUIRED BATTERIESStation: 4x AASensor: 2x AAA

The ASTRO & MARINE binoculars from BRESSER are ideal for astronomy and maritime use, e.g. sailing and water sports enthusiasts. Robust and weatherproof per IPX6 levelThanks to their ergonomic rubber armouring, these binoculars fit securely in the hand and are also well protected against shocks and bumps. The binoculars are waterproof and filled with nitrogen. This effectively prevents fogging of the lenses, even in unfavourable weather conditions. Lightweight with tripod connection threadThe robust, yet very light construction is made possible by the most modern magnesium housing construction. Magnesium is around 35% lighter than aluminium. Due to the moderate 10x magnification and the low weight, these 10x50s are also very well suited for hands-free use. Nevertheless, there is a tripod connection thread on the centre axis. This means that the ASTRO & MARINE model can also be mounted securely on a photo tripod using the tripod adapter (Art.4914925) which is included as part of the package. Although this is not absolutely necessary with a magnification of 10x, it is highly recommended, especially for long-time astronomical observations, in order to obtain an absolutely steady image. Eyepieces for comfortable viewingThe precise single eyepiece focusing (SF) makes it possible to focus the binoculars once and then clearly observe all resolvable objects in the night sky, or on the horizon. In addition, this design prevents accidental change of focus. Foldable rubber eyecups and eyepieces with a comfortable eye relief distance (WP) of 20mm also allow those who have to wear glasses to observe, to use the entire field of view. High quality opticsThanks to fully multi-coated Bak4 optics, large 50mm objective lens diameter and the well-corrected eyepieces with 5 lenses in 3 groups, these excellent binoculars produce sharp and brilliant images. The maximum reduction of stray light achieved by internal baffles and housing/edge blackening, results in the best possible optical image and perfect contrast, even in difficult light conditions and especially at night.FEATURESBinoculars for astronomy, landscape observation and water sportsWaterproof per IPX6 level and filled with nitrogen to prevent lens foggingAlso for use in unfavourable weather conditionsExtremely high light gathering optics, making them ideal for night-time observationModerate magnification for a steady image, even when hand-holdingMagnification: 10x / Lens diameter: 50mmSingle eyepiece focus (SF) and foldable rubber eyecups, also suitable for spectacle-wearersWide pupil distance (WP) of 20mm for comfortable viewingWell corrected eyepieces for ultimate image sharpness and pinpoint star imagesModern multi-layer coatings on all lens surfaces for high light transmissionErgonomic rubber armouring - very good grip and protects against shocks and bumpsRobust construction, yet still lightweight due to magnesium housingDimensions: 191 x 202 x 66 mm / Weight: 1165 grams / Colour: blackTripod connection thread 1/4 inch available on the binocular bridgeMetal photo tripod adapter already included in deliveryWHAT'S INCLUDED Binoculars Carrying strap Dust caps Nylon travel bag Photo tripod adapter (Art. 4914925) Instruction manual
