Lunt solar LS50FHa filter with B600 blocking filter. $900.00 and includes delivery in the CONUSA. PayPal payment preferred.

Overview of the LS50 Hydrogen-alpha Filter Set
50mm aperture (no central obstruction) integrally tuned etalon for use on any customer supplied refractor. System includes the B600 blocking filter standard, which provides full disk images on telescopes up to 600mm focal length. Larger blocking filters suitable for longer focal length telescopes or imaging applications are also available as options.
Because the LS50FHa has an estimated bandpass of <0.75 Angstroms it is capable to providing high contrast views of some surface and all edge detail. Adding an additional etalon system (double-stacking) will reduce the bandpass to ~<0.55 (dependant upon scope) allowing for higher resolution viewing and/or imaging.

I also have available an adapter plate for using the filter on a Televue 76 $15.00.
