Lunt Solar Systems - 160mm Ha Etalon-Filter-System with B1800 blocking filter for 2 inch

Introducing the LS160 Hydrogen-alpha system. We are offering the 160mm aperture integrally tuned etalon for use on any customer
supplied refractor. System includes the B1800 for use on telescopes up to 1620mm focal length. Blocking filter required.

Because the LS160 has an estimated bandpass of <0.7 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 <0.5 (dependant upon scope) allowing for higher
resolution viewing or imaging.

Delivered with order:
• Main Filter
• Blocking Filter (for 2 inch eyepiece-holder)
• Transport case
