Introducing the LS75 Hydrogen-alpha system..... Although Lunt is in the final stages of patenting the large filter design. Lunt Solar does have pricing and projected delivery times. The LS75, LS100, and LS160 all have a unique design feature which allows for a more stable filter that is also less prone to de-contacting. (more information as is becomes available). System includes the B600 standard for use on telescopes up to 600mm focal length. *Blocking filter required.

 Because the LS75 has an estimated bandpass of <0.75 Angstroms it is capable to providing high contrast views of both surface and edge detail. Adding an additional etalon system will reduce the bandpass to ~<0.55 (dependant upon scope) allowing for higher resolution viewing and/or imaging.
