Lunt Solar Systems - 75mm Ha Etalon-Filter-System with B3200 blocking filter for 1.25 inch

Introducing the LS75 Hydrogen-alpha system. To kick off the new company we are offering the 75mm aperture (no central obstruction)
integrally tuned etalon for use on any customer supplied refractor. System includes the B3200 blocking filter which provides full
disk images on telescopes up to 2880mm focal length.

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.

Delivered with order:
• Main Filter
• Blocking Filter (for 1.25 inch eyepiece-holder)
• Transport case
