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
£3,698.00*
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 CAA-RF 0.8x reducer/field-flattener for nighttime photography with LS80MT, LS100MT & LS130MT telescopes
£598.00*
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
