This ERF can be used with H-alpha, Sodium, and Helium D3 solar filters, but is incompatible with calcium wavelengths. \u003c\/p\u003e \u003cp\u003eChoose the ERF aperture size to approximately match your OTAs front lens. Select the correct filter cap size by measuring the outside diameter of the OTA's front retaining ring, including fastener heads, and choose the ERF with the smallest inside diameter that will fit over the end. A set of screws is included to secure the ERF into place. This ERF's cap has an inside diameter of 46.0cm (18.110\").\u003c\/p\u003e \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cspan\u003eUPC: 724696425687\u003c\/span\u003e \u003c\/div\u003e \u003c\/div\u003e\u003cdiv\u003e \u003cdiv\u003eIn the Box\u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003eDayStar Filters 125mm-Aperture Off-Axis Energy Rejection Filter (460mm Cap Diameter)\u003c\/div\u003e \u003c\/div\u003e \u003cul\u003e \u003cli\u003e 3 x Set Screws \u003c\/li\u003e \u003cli\u003eLimited 10-Year Warranty\u003c\/li\u003e \u003c\/ul\u003e \u003c\/div\u003e \u003c\/div\u003e All product and company names are trademarks™ or registered® trademarks of their respective holders.
