Product information "LUNT CAA-RF 0.8x reducer/field-flattener for nighttime photography with LS80MT, LS100MT & LS130MT telescopes"
​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.

FEATURES
  • Shortens focal length of F/7 ED telescopes by a factor of 0.8x

LUNT LS80MT/B1200R&P Multipurpose APO Telescope for Sun + Night-Sky
​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. 2-lens ED Apo telescope with FPL-53 glass, 80mm aperture and 560mm focal length - very good image quality for H-Alpha solar observation and also for observing the starry sky at night.With innovative air pressure tuning system, good 2 inch (50.8mm) R&P focuser, and B1200 blocking filter.Solar observing in H-alpha:The LS80MT/B1200 is a complete telescope for observing the sun in H-alpha light, with 80mm free aperture (no central obstruction) and 560mm 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 R&P focuser with 10:1 reduction.Blocking-filter is the B1200. The B1200 is good for visual solar observing. Also solar imaging is possible by cameras with small sensor chip. We recommend a LS80MT with B1800 blocking-filter by using cameras with large sized sensor 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. With the additionally available conversion kit (item number 0551330) the 2-lens ED Apo refractor can then be used as a normal telescope with 80mm aperture and 560mm focal length for observation and photography of the night sky. The FPL-53 doublet lens offers an low colour aberration image. Common 2 inch star diagonals can be used at the high quality R&P focuser of the conversion kit 0551330.Please note that the optionally available conversion kit 0551330 is absolutely necessary if the telescope should be used at night.More applications:With additionally available accessories the LS80MT offers even more possibilities!- Double-StackThe LS80MT telescope can optionally be upgraded with the additionally available double-stack module DSII/SFPT (item number 0551395). The DSII system is a internal double-stack module. 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 LS80MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.This makes the LS80MT a completely universal usable ED Apo telescope of very good quality!FEATURES2-lens ED APO refractor, FPL-53Aperture: 80mm (no central obstruction)Focal length: 560mmBandwidth: internal Etalon with <0.7 AngstromTuning: air pressure tuning system Pressure-TunerBlocking filter: B1200 with 1.25" and T2 connectionFocuser: R&P with 10:1 reductionTwo tube-ring with handleSol-Searcher installed inside handleDovetail bar at GP-level for astronomical mountsWeight: 4.95kgLength with blocking filter and dew-shield: 62cmLength without blocking filter and removed dew-shield: 50cmSCOPE OF DELIVERYLS80MT Multipurpose TelescopePressure-TunerB1200 blocking filter in star-diagonal housing2 inch R&P focuser with 10:1 reductionTube rings with dovetail bar and sol-searcherTransport case (78x33x23cm)Instruction manualConversion kit for observation of the starry night sky (0551330) not included!

BRESSER T2 Extension Tube Set
Set of 5 extension tubes with T2 thread on both sides for exact distances and secure hold of cameras for astrophotography. Also comes with SC to T2 thread adapter.In astrophotography, most cameras are connected to a telescope via a T2 thread (M42x0.75), the most popular international standard. However, in many cases, T2 and T2-ring adapters for connecting telescope focusers to a camera are not sufficient, as specific distances must also be observed. This is especially important when using correctors, reducers or flatteners. This extension tube set, which consists of 5 mm, 7.5 mm, 10 mm, 15 mm and 30 mm tubes, will allow you to obtain almost any distance using the corresponding combination. Each tube has a T2 interior thread on one side and a T2 exterior thread on the other side.Most telescopes either include a T2 thread adapter, or the eyepiece can be used with a simple T2 thread adapter with a 2” plug-in diameter (item no. 0510365).However, Maksutov-Cassegrain, Schmidt-Cassegrain, ACF or Ritchey–Chrétien telescopes may use a so-called SC thread. To allow you to use this extension tube set with these telescopes, the set also includes an SD to T2 thread adapter.FEATURES5 T2 tubes with lengths from 5 mm to 30 mmCombination of tubes allows you to obtain distances of 5 mm to 67.5 mmFor exact camera distances in astrophotographyDELIVERY CONTENT5x T2 extension tubes (5/7.5/10/15/30 mm)1x SC to T2 thread adapter

LUNT O-ring for Pressure-Tuner at LS50THa solar telescopes
​Spare part for Pressure-Tuner of LS50THa H-alpha solar telescopes from LUNT SOLAR SYSTEMSA rubber O-ring is installed into the Pressure-Tuner of Lunt Solar Systems LS50THa solar telescopes to seal the air-pressure tuning system. Over time, the rubber of this O-ring can age and become porous, whereby the air-pressure can then no longer be maintained. When this happens, the old O-ring can be replaced by this spare part. The replacement is simple and can be done by the user. Installation instructions can be found here under the tab "Manuals" as a PDF for download.After replacing the O-ring, the piston and cylinder of the Pressure-Tuner can be re-greased with grease available under part number 0558350.Please note that this spare part can only be used on the Lunt Solar Systems LS50THa H-alpha solar telescopes. If the problem occurs on the larger THa or MT series telescopes, the larger O-rings with part numbers 0558330 or 0558340 must be used there.FEATURESInner-diameter: 31mmOuter-diameter: 39mmCannot be used separately, only as a replacement part on the Pressure-Tuner of the LS50THa telescopes from Lunt Solar Systems.It does not matter what blocking filter is at the LS50THaSCOPE OF DELIVERYSpare part one O-ring for pressure tuner of LS50THa

LUNT Ca-K filter-module for LS130MT
This Ca-K module can be used at the LS130MT/B1200 and LS130MT/B1800 telescopes to observe the Sun also in the Calcium-K line. At the LS130MT/B3400 additionally the conversion kit for the LS130MT is required (item number 0551696).You can use this Ca-K module with your LS130MT telescope to observe and photograph the Sun not only in H-alpha, but also in the blue calcium-K wavelength. Here again completely different phenomena become visible on the Sun than in H-alpha.This Ca-K module was specially designed for the LS130MT H-Alpha telescope. If the H-alpha Etalon unit is removed from the LS130MT, the Ca-K module is simply inserted into the focuser instead of the blocking-filter.The additional conversion kit 0551696 is necessary at the LS130MT/B3400, because at this telescope the blocking filter is fix installed inside the focuser.For human eyes, the calcium-K light is just at the limit of the visible range. Many people have problems with visual observation. However, this does not apply to photography, where the Ca-K module shows everything the Sun has to offer in this wavelength.SCOPE OF DELIVERY2'' Ca-K Module for LS130MT telescopeInstruction manualLS130MT telescope and conversion kit not included! Can only be used together with an LS130MT solar telescope, at LS130MT/B3400 additional conversion kit 0551696 necessary.This Ca-K module is also available for the LS130MT/B3400 as a set together with the required conversion kit (item number 0551695).

LUNT HRG/SFPT anti-reflection filter for DSII/SFPT double-stack at LS80MT & LS100MT telescopes
The anti-reflection filter is an accessory for the DSII/SFPT double-stack module for the Lunt Solar Systems LS80MT and LS100MT telescopes. Reflections that may occur there can be effectively reduced with this anti-reflection filter if necessary.At the LS80MT and LS100MT multipurpose telescopes from Lunt Solar Systems, double-stacking is possible in H-alpha mode for solar observation with the internal DSII/SFPT double-stack modules (item number 0551395). The DSII modules reduce the bandwidth to <0.5 Angstroms. The DSII modules are designed to show better the surface details of the Sun, the contrast is significantly increased, and therefore filaments and active areas are better visible.But the DSII modules can also induce reflections, which can show up as a strong brightening around the sun. This so-called ''glow'' is not a problem when observing the solar surface. But it can complicate the observation of prominences, and many observers find it disturbing. The HRG/SFPT anti-reflection filter is designed to solve this problem. The filter effectively reduces the reflections. But please also note that the image will become darker by using this anti-reflective filter.The HRG/SFPT anti-reflection filter is easy to install. It is not necessary to return the telescope to the manufacturer, the filter can be easily installed by the user.This filter cannot be used separately! It can only be used on a Lunt Solar Systems LS80MT or LS100MT telescope together with a DSII/SFPT Double-Stack module.SCOPE OF DELIVERYHRG/SFPT anti-reflection filterInstruction manual
