The Herschel TS-Optics 1.25 "wedge is a specialized accessory dedicated to solar observations with the use of refractors.
The wedge is equipped with a high-quality interference filter that blocks approximately 99 percent of the sunlight and thus enables safe observation of the sun's disk. In addition to the basic filter, the set also includes a polarizing filter that allows to obtain a much better contrast than in the case of using standard filters mounted on the telescope lens.
The wedge casing is designed in such a way as to best reflect the heat accumulating in it to the environment.
Attention! Observing the sun is always associated with the risk of irreversible damage to eyesight. Before each use of the wedge, check the condition of the filters and the correctness of their mounting, and in the event of any irregularities, discontinue observation. • high efficiency of cutting sunlight for safe observations • an interference filter with a maximum transmission for the 540 nm line • additional polarizing filter included • heat sinks that facilitate heat dissipation from inside the housing • construction: Herschel wedge • compatible telescopes: refractors • mount on the telescope side: 1.25 "/ M35x0.75 thread on the housing • mount on the observer side: 1.25 "/ T2 (male) / M35x0.75 on the housing • solar filter passband maximum (CWL): 540 nm • bandwidth of the solar filter passband: 40 nm • efficiency of cutting out the light: 99% • additional filter: polarizing • heat dissipation: through heat sinks in the housing • housing finish: black mat • Herschel TS Optics 1.25 "wedge with narrowband filter • additional polarization filter • plugs 24 months
