This is a Tuthill 3 angstrom prominence filter. it has a built-in heater and a focusing 27mm eyepiece with occulting disc. The filter has a fine tilt control to tune contrast. It was purchased in the mid 90's and easily shows prominences in my large refractor. However at 3 angstroms it will not show surface detail. The filter requires an F30 to F38 light cone. I will include a 6" #92 Kodak gel which I used as an ERF. $350 + shipping
