Product Description

To kick off the new company we are offering the 50mm aperture (no central obstruction) integrally tuned etalon for use on any customer supplied refractor. System includes the B1800 blocking filter for use on telescopes up to 1800mm focal length.

Because the LS50 has an estimated bandpass of <0.75 Angstroms it is capable of 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.

System Includes:

LS50 Ha Filter
B1800 Blocking Filter (other sized available by request)
Re-enforced case with foam
