Vixen Flattener HD Kit für FL55SS Telescopes

Convert your FL55SS fluorite refractor into a high-performance astrograph The kit includes a high-performance reducer, flattener and the ''EX TUBE 66'' extension tube, which was developed for the FL55SS Fluorite Apo Refractor and improves the photographic performance by flattening the image right up to the edges. Ultra-sharp image over the entire field of view of the DSLR full-frame sensor Designed for prime-focus photography with the FL55SS, the Flattener HD flattens the entire field of view of full-frame DSLR cameras. The 44 mm image circle covers the entire field of view of a full-frame DSLR camera. When used in combination with the HD5.5 Reducer, the focal length is reduced by 0.79x (from f5.5 to f4.3) and the illuminated area retains a diameter of 44 mm, which significantly improves the sharpness across the entire field of view of the DSLR camera. 96% illumination to the edges of the field of view The Flattener HD was specially developed for the FL55SS refractor in order to reduce light loss to a minimum. The field of view is fully illuminated up to the edges. Exceptionally high contrast The same anti-reflective AS coatings used on our high-end VSD 100 f/3.8 astrograph are also used here to provide an outstanding light transmission of 99.9% per lens surface. In addition, the matte black surface of the Reducer HD kit eliminates loss of light, ghosting and scattered light.

Vixen has developed a new generation of SX mounts for demanding observers and astrophotographers. The SXD2WL mount is simply operated via a Wifi module with a smartphone or tablet. By controlling the mount with your smartphone using the free STAR BOOK Wireless app, you can easily use sky navigation functions such as automatic GoTo panning of celestial objects via your smartphone or tablet. By eliminating the power consumption of the conventional LCD (STAR BOOK TEN), the power consumption on the mount is reduced by up to 20%, thus enabling longer astronomical observation and astrophotography. When the desired celestial object is selected from a list, it is automatically panned into the telescope's field of view and tracking begins. An existing STAR BOOK TEN controller can also be used on this mount without any problems. Equipped with the same precision stepper motors as the top model, the AXD mount, the SXD2WL brings a new standard of performance and precision to the Vixen mount family. With a photographic load capacity of 15 kg, the axis cross of the mount weighs just 9.2 kg making it ideal for mobile observations. In addition, the motors mounted in the lower part of the mount also serve as a counterweight, so the mount requires fewer weights for balancing. The SXD2 mount in detail Precision stepper motors and micro-step motion control system At the heart of the SXD2 are the precision stepper motors, which offer better performance and response than previous models. The micro-step motion control system offers powerful and yet very smooth drive characteristics, which are given both in fine movements and in fast pans. Built-in bearings The bearings of the RA and DEC axes and the worm shafts have been significantly improved to reduce the load on the motors. As a result, the motors move much more smoothly than in previous models. High-precision worm gears High-precision processing technologies eliminate worm gear errors. The edges of the two worms and worm wheels are particularly smooth, enabling very precise tracking. Declination axis as counterweight The solid motor units are installed in the lower part of the declination axis so that the center of gravity of the SXD2 is below the intersection point of the RA and DEC axes. This means you need fewer additional counterweights. Latitude setting The latitude is adjustable between 0 and 70 degrees (divided into 3 zones and adjustable +/- 15 degrees per zone, for high, medium and low latitudes); latitude scale in 2-degree increments; fine adjustment with a tangent screw head, approx. 0.8 degrees per turn. Built-in PFL-II polar finder with illumination The built-in 5x20mm polar finder with 10° field of view has a 3-star alignment system. This eliminates the inconvenience of setting the date and original time. The illuminated reticle with variable brightness and automatic switch-off is adjustable in 8 levels and illuminated in red. The adjustment accuracy is 3 arc minutes. The wireless module in detail The Vixen Wifi adapter for EQ mounts allows you to control your Vixen mount via a smartphone or tablet. With the smartphone app STAR BOOK Wireless (free of charge) you can navigate the sky without any cables. The app turns your smartphone or tablet into a control unit for the equatorial mount in no time at all. The response delay of the mount, which is considered the biggest disadvantage of wireless connections, has been reduced to a level comparable to wired connections. Reduced power consumption compared to conventional controllers with LCD monitor The power consumption of the mount is reduced by up to 20%, allowing longer observations than with conventional wired controllers such as the STAR BOOK TEN. Operation similar to the STAR BOOK TEN controller. The STAR BOOK Wireless app has a similar structure to the STAR BOOK TEN controller. Depending on the star map setting, it contains up to 259,000 celestial objects. Tap on a celestial object in the object list and start the GoTo. The mount will now automatically move to this target and bring it into the telescope's field of view. All the popular features of the STAR BOOK TEN are retained Convenient operation When looking through the telescope operate the mount by swiping on the app's star chart. As there are no buttons, simply slide your finger over the star chart to operate the mount conveniently. Extensive astronomical data included In addition to data on easily observable celestial bodies such as Messier objects, NGC objects and IC objects, this also includes the sun, moon, planets, comets and dwarf planets. High-precision alignment By aligning the mount to one or two stars, you can already achieve fairly precise positioning. By aligning the mount to three or more stars, you can achieve high-precision alignment of the mount for high magnifications. The objects are then approached precisely and centrally in your telescope's field of view. The alignment information is saved and can be retained even when the device is switched off. By leaving the telescope in its current state after completing an observation without moving it, you can start the automatic installation with the same settings for the next observation.  Individual setting options As with the STAR BOOK TEN control unit, the app offers various individual settings, such as gear backlash compensation, night mode in red, autoguider and variable GoTo speed and LED brightness. You can also set the timing of the reversal of the objective tube (meridian flip) as desired. Even if the object moves to the south during tracking, you can prevent the telescope tube from reversing. Important note: Cannot be used on old SX mounts with the old blue Star Book! Technical information about the Wifi module: CPU with 32-bit CISC processor 120 MHz The unit is connected to the mount via a D-SUB 9PIN connector as with the STAR BOOK TEN. It has a 6-pin 6-wire modular plug for external autoguider operation.

Highly corrected 127mm air-spaced triplet apochromat (with three lenses) and carbon fibre tube and a 2.5" high-precision HEXAFOC focuser. NEW: Now with hybrid viewfinder shoe to accept different viewfinder holders.    Apochromats are the ultimate choice in small to medium sized telescopes: the combination of compactness, transportability, very high image contrast and sharpness together with excellent astrophotographic performance cannot be bested. The advances in glass manufacturing during the last few years have made true apochromats available to more astronomy enthusiasts than ever before. The new Explore Scientific FCD-100 CF Hex represents another major improvement in this field - the overall correction (colour and spherical) is setting new standards in this price class. The optical design shows a polystrehl value of 0.97 indicating a level of correction that is absolutely top of the line.This excellent apochromat is a very versatile telescope: its reasonably fast f-ratio makes for short exposure times when imaging deep sky objects, but it is still of a significant focal length, making higher power planetary and lunar observation comfortable without having to use really high magnification eyepieces. The high contrast and sharpness of the image provide breathtaking views of large objects like the North America nebula or the Andromeda galaxy, as well as tack sharp planetary images. The telescope is lightweight and compact - the dew shield slides down the tube to minimize size for transportation. Revolutionary glass and precision manufacturing come together to deliver a telescope that offers observing and imaging at the highest level. The Carbon Fibre construction allows this telescope to be used on lower capacity mounts, increasing convenience and portability. Although there are smaller instruments available, the combination of aperture and optical excellence at such a low weight and compact tube makes this an excellent travel scope. The well-designed 2.5" HEXAFOC focuser with 10:1 reduction is perfect for both visual and astrophotographic use - the large inner diameter of 65mm prevents vignetting by the focuser when the telescope is used for astrophotography with large sensors (full frame and above).We offer the very popular EXPLORE SCIENTIFIC Triplet ED APO Refractors in 3 different product lines:Essential Line: HOYA FCD-1 Glass lens, AL-Tube, 2.0" Rack & Pinion Focuser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112084(AL), 0112106(AL), 0112132(AL)), 0112155(CF + 3"FT)). Professional Line: HOYA FCD-100 Glass lens, AL/CF-Tube, 2.5" HEXAFOC Focuser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112086(AL), 0112108(AL), 0112109(CF), 0112134(AL), 0112135(CF))High-End Line: OHARA FPL-53 Glass lens, Carbon(CF) Tube, 3.0" Feather-Touch Focuser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112165(CF))SPECIFICATIONSAperture: 127mmFocal Length: 952mmFocal ratio: f/7.5Design: Apochromat with three lenses, two air spaces and FCD-100 glassWeight: 5.2kg, lightweight due to carbon fibre tubeBackfocus: 150mm above 2" adaptorHybrid viewfinder shoe to accept different viewfinder holdersWHAT'S INCLUDED Optical tube with retractable dew-shield2.5" HEX focuser with 1:10 gear reduction  2" Star Diagonal 99% reflectivityTube rings with dovetail plate and handle Extension tubes for focuser (2pcs)Dust caps for front-lens and focuserHybrid viewfinder shoe
