Product information "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.

LUNT DSII/SFPT double-stack module for LS80MT & LS100MT
Double-stack module for more contrast and details on the solar surface with the LS80MT and LS100MT telescopes.At the LS80MT and LS100MT telescopes double-stacking is possible with this internal DSII double-stack module when observing the sun in H-Alpha. The DSII modules reduce the bandwidth to <0.5 Angstrom. They are designed to show the surface details of the sun better, the contrast is significantly increased and therefore filaments and active regions are better visible.The DSII/SFPT module is designed exclusively for use in LS80MT and LS100MT telescopes, it cannot be used at other telescopes. It is used between the existing H-Alpha unit and the focuser on the telescope. Installation is simple, no additional adapters or tools are required.FEATURESBandwidth: <0.5 AngstromTuning: Air Pressure Tuning System SCOPE OF DELIVERYDSII module with internal Etalon for LS80MT and LS100MT telescopesPressure Tuner System(LS80MT or LS100MT telescope not included!)

LUNT Blue-Glass 20mm for B400 to B1800 blocking-filters
​Spare part for blocking-filters from LUNT SOLAR SYSTEMS, suitable for B400, B500, B600, B1200 and B1800 blocking-filters.The H-alpha telescopes and filter systems from Lunt Solar Systems each include a blocking-filter. The blocking-filters have a blue colored filter part on the side facing the telescope. This blue colored filter parts may become a milky white layer at older blocking-filters if the blocking-filter was storded at high air humidity for some time. Please always store H-alpha telescopes and filters as dry as possible. If this blue colored filter part has become a milky white layer, it can be replaced with this spare part. The replacement is easy and can be done by the user himself. Installation instructions can be found here under the "Manuals" tab as a PDF for download.Please note that this replacement part can only be used on Lunt Solar Systems blocking-filters B400 to B1800. If the problem happens with the large B3400 blocking-filter, the B3400 must be sent to our service department for repair.FEATURESDiameter: 20mmCannot be used separately, only as spare part at blocking-filters from Lunt Solar SystemsFor B400, B500, B600, B1200 and B1800 blocking-filtersIt does not matter if the blocking-filters are installed in 90° zenith-mirrors or straight extension-tubesSCOPE OF DELIVERYSpare part 20mm blue glass for B400 to B1800 blocking-filters
