Details
H-alpha Single Pass Front Mount Etalon System for telescopes with 1.25" focuser and up to 1080mm focal length.
Introducing the LS35 Hydrogen-alpha system. To kick off the new company we are offering the 35mm aperture (no central obstruction) integrally tuned etalon for use on any customer supplied refractor. System includes the B1200 blocking filter which provides full disk images on telescopes up to 1080mm focal length.
Because the LS35 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 ~<0.5 Angstroms.
Delivered with order:
• Main Filter
• Blocking Filter (for 1.25" focuser)
• Transport case
