LUNT LS60FHa H-alpha double-stack solar filter

High resolution deep sky camera with large SONY EXMOR IMX-571 APS-C CMOS sensor and active cooling. This camera's extreme sensitivity is achieved through SONYs backside illumination technology. This camera should appeal to both advanced users and those looking to move up from DSLRs for more serious deep sky imaging.Enter the world of astrophotography now. With the new EXPLORE SCIENTIFIC Deep Sky Astro camera you get a modern complete package for straightforward shooting of astro photos and videos. Finally, an easy-to-use camera for capturing galaxies, star clusters, the moon and even planets with high resolution and low sensor noise. Thanks to the fast USB 3.0 computer interface, all image data is transferred within a few seconds. Long waiting times for images are now history. Simply connect the camera to your telescope using the T2 female thread (M42, 0.75 mm) or the supplied 2" (50.8 mm) plug-in adapter and after installing the drivers and the included EXPLORE Capture recording and editing software, you are ready to take the first real astro photos with a highly specialized camera for your application.  The EXPLORE Capture Pro software included in this package not only offers the basic functions required for image and video capture, but also many helpful special functions for image post-processing and camera setup. Functions such as live image display, exposure settings, white balance, dark image subtraction, stacking, timelapse recording and much more can be configured individually. This very sophisticated software makes your entry into astrophotography really easy. With the automatic settings you can produce absolutely presentable results without any previous knowledge. As soon as you feel confident, simply switch off the automatic settings and gradually explore the software's more individual professional settings. The new EXPLORE SCIENTIFIC Deep Sky camera has a highly sensitive and very low-noise SONY EXMOR IMX-571 APS-C CMOS Sensor, which can be cooled down to 40 °C below ambient temperature by the two-stage thermoelectric cooling. In contrast to normal DSLR cameras, this guarantees much lower noise and fewer hot pixels in your shots. The images are not only much sharper and more brilliant, but also contain more usable image information. Through the carefully automatically-controlled setting of the desired camera temperature, the it's easy to create of dark frames which can be re-used under similar shooting conditions - speeding up your processing considerably. The large-format CMOS sensor with 28.3 mm diagonal also allows large image fields and simplifies the adjustment and centering of objects considerably. The secret to the high light sensitivity of this camera is SONY's new back illuminated EXMOR CMOS sensor. It increases the quantum efficiency to up to 80 % at 533 nm, which leads to an extremely high sensitivity and subsequently particularly bright and high-contrast photos.The camera has a built-in USB hub with 2 x USB 2.0 ports at the rear. Connect your additional autoguider camera or motor focus etc. via a short USB cable and reduce the risk of cable tangles and cable breaks. Separate cable connections between your accessories and your computer are no longer necessary. A sturdy hard case for the camera plus accessories is also included. IMPORTANT NOTES: Don't get confused by the megapixel data and the contrary price structure. In the field of astronomy, the key criterion is not the sensor resolution but the maximum light sensitivity. The main goal is to capture as much light as possible in a short time.DOWNLOAD latest camera software and drivers see download folder "Manuals" or here: http://www.touptek.com/download/showdownload.php?lang=en&id=2 Sample photos made by Lóránd Fényes in Hungary: https://fenyeslorand.hu/m31/https://fenyeslorand.hu/ic349_merope_nebula/https://fenyeslorand.hu/asztrofotok/Field of view for different focal lengths in arc minutes and degrees: 400 mm - 201´ x 135´  (3.4 x 2.3 degrees)500 mm - 161´ x 108´  (2.7 x 1.8 degrees)600 mm - 134´ x 90´  (2.2 x 1.5 degrees)700 mm - 115´ x 77´  (1.9 x 1.3 degrees)800 mm - 100´ x 67´  (1.7 x 1.1 degrees)900 mm -  89´ x 60´  (1.5 x 1.0 degrees)1000 mm - 80´ x 54´  (1.3 x 0.9 degrees)1250 mm - 64´ x 43´  (1.1 x 0.7 degrees)1500 mm - 53´ x 36´  (0.9 x 0.6 degrees)1750 mm - 46´ x 31´  (0.8 x 0.5 degrees)2000 mm - 40´ x 27´  (0.7 x 0.45 degrees)FEATURESCamera type: ASTRO Colour Camera 26.0MP ATR3CMOS16000KPA Data output: single pictures and video Image Sensor: SONY EXMOR IMX-571 CMOS Colour Sensor Adjustable resolution: 6224x4168 / 3104x2084 / 2064x1386 Adjustable binning: 1x1 / 2x2 / 3x3 Frame rate per second (FBS): 6.8 / 28 / 63 Physical sensor size in pixels: 6224 x 4168diaginal: 28.3 mmMegapixel: 26 MP Sensor size: 23.48 x 15.67 mm (APS-C format)Pixel size: 3.76 µm x 3.76 µm Bit depth: 8 Bit / 16 BitBackfocus: 17.5 mm  Shutter Type: rolling shutterInternal camera memory: 512MB DDR 3 RAMThermoelectric cooling with fan: yes, up to 40°C below ambient temperature Adjustable exposure times: 150µs to 60min Operating temperature: -10 to +50°C (30-80% RLH) Cable length USB 3.0: 150cm DC cable length power supply: 200cm CNC machined aluminium housing Camera diameter: 80mm; length: 102mm Camera weight: 0.53 kg Camera connection diameter: 2.0 inch ( 50.8mm) Camera connection thread: T2 (M42x0,75mm) Filter thread: Yes, 2.0 inch in receptacle Camera connection to PC: USB 3.0 Built-in USB hub with 2 x USB 2.0 ports Power supply: Power supply 12 Volt 3,0 Ampere included Software: EXPLORE Capture included Camera driver and ASCOM driver includedOperating system: WINDOWS 10 + 11 PC requirements: CPU Intel Core2 2.8Ghz or higher / 2 GB Ram / USB 3.0 WHAT'S INCLUDEDDeep Sky Astro Camera 26.0MP Telescope adapter T2 thread to 2.0" (50,8mm) USB 3.0 connection cable 150cm Power supply 230V/12V 3.0A Dust cap Software CD Hard case Instruction manual

Modular designed multipurpose telescope, both for observing the sun in the H-alpha wavelength, as well as for night sky observations. Easy conversion between the different applications with a few simple steps. Excellent image quality due to 2-lens ED optics with 70mm aperture for night sky observation, and 60mm usable aperture for H-alpha solar observation.With innovative air pressure tuning system, high-quality 2 inch (50.8mm) Rack&Pinion (R&P) focuser, and B600 blocking filter.Solar observing in H-alpha:The LS60MT/B600 is a complete telescope for observing the sun in H-alpha light, with 60mm free aperture (no central obstruction) and 420mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing protuberances at the sun's edge, filaments and flares on the surface, and much more. An internal Etalon filter achieves a bandwidth of <0.7 Angstrom with the innovative air pressure tuning system Pressure-Tuner. Tuning is done by slightly changing the air pressure in a pressure chamber inside the telescope. This changes the refractive index of the air, making it easy to tune to the H-alpha line. The pressure tuner guarantees a homogeneous image, without central obstruction, and a permanently protected Etalon without erosion. A set of collimating lenses installed in the telescope ensures best performance.Fine adjustment is achieved with a solid 2 inch Rack&Pinion focuser with 10:1 reduction.Blocking-filter is the B600. The B600 is good for visual solar observing. Also solar imaging is possible by cameras with small CCD chip. We recommend a LS60MT with B1200 blocking-filter by using cameras with middle or large sized CCD chips.The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25 inch eyepieces and with a T2 camera connection.Observing the starry night sky:The H-alpha Etalon system can be removed from the telescope in a few easy steps thanks to its modular design. The 2-lens ED refractor can then be used as a normal telescope with 70mm aperture and 420mm focal length for observation and photography of the night sky. The ED Doublet lens will offer an excellent image. It can be used with a standard 2 inch zenith mirror at the R&P focuser.With an additional Amici prism, the telescope can of course also be used during the day for nature and landscape observations.This makes the LS60MT, with its small dimensions and low weight, also an ideal travel telescope for all applications!More applications:With additionally available accessories the LS60MT offers even more possibilities!- Double-StackThe LS60MT telescope can optionally be upgraded with the additionally available double-stack filters LS50FHa or LS60FHa (part numbers 0550200 and 0550250). These filters will be simply screwed on the front of the LS60MT, no additional adapters are necessary. Thereby a bandwidth of <0.5 Angstrom is achieved for H-alpha solar observation. Therefore much more details on the solar surface will become visible.- Solar observing in White-LightIf the H-alpha unit has been removed, of course either a sun filter to be installed in front of the objective, or a Herschel-wedge at the focuser can be used to observe the sunspots in White-Light.- Solar observing in Ca-K wavelengthCertainly, the Ca-K filter modules from Lunt Solar Systems can also be used at the LS60MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.This makes the LS60MT a completely universal usable telescope!FEATURES2-lens ED refractor, FPL-51Aperture: 70mmUsable aperture in H-alpha: 60mm (no central obstruction)Focal length: 420mmBandwidth: internal Etalon with <0.7 AngstromTuning: air pressure tuning system Pressure-TunerBlocking filter: B600 with 1.25 inch and T2 connectionFocuser: Rack&Pinion focuser with 10:1 reductionTube-ring with 1/4-20 tapped base (standard thread for photo-tripods)Weight with H-alpha unit: 3.8kgWeight without H-alpha unit: 2.6kgLength with H-alpha unit and blocking filter: 40cmLength without H-alpha unit: 31cmSCOPE OF DELIVERYLS60MT Multipurpose TelescopePressure-TunerB600 blocking filter in star-diagonal housing2 inch Rack&Pinion focuserTube ring with 1/4-20 connection for mounting on photo-tripodsTransport case (53x33x17cm)Instruction manual

​Field-flattener and focal length reducer for deep-sky astrophotography. Designed for the multipurpose APO telescopes of the Lunt-Solar-Systems LS80MT, LS100MT and LS130MT series.At the telescopes of the MT series from Lunt Solar Systems, the H-Alpha filter unit for solar observation can be removed, then these telescopes can be used as high quality ED APO's for observing and photographing the night sky.This accessory for the LS80MT, LS100MT and LS130MT telescopes shortens the focal length by a factor of 0.8x, providing a larger field of view for deep-sky astrophotography. This also allows shorter exposure times. At the same time, the field of view is flattened for photography.On the camera side, the reducer/field-flattener has a T2 male thread (M42x0.75). DSLR cameras can be connected here directly with a normal T2 ring.For other cameras, an M39x0.75 female thread is available in addition to the T2 male thread. The distance between reducer/field-flattener and camera sensor should be around 50 to 55mm. Normal T2 extension sleeves can be used to achieve this distance.On the telescope side, the following connections are provided: 2 inch socket, M54x0.75 male thread, M63x1 male thread and M68x1 male thread.FEATURESShortens focal length of F/7 ED telescopes by a factor of 0.8xFlattened field of view for photographyT2 thread for camera connectionWorking distance 50 to 55mm2 inch socket and M54x0.75 thread for connection to telescopesAdapter to M63x1 and M68x1Weight only reducer/field-flattener: 0.25kgWeight together with adapter to M63 & M68: 0.36kgSCOPE OF DELIVERY0.8x reducer/field-flattenerAdapter to M63x1 and M68x1
