ALTAIR nickaltair Posted March 24 ALTAIR Share Posted March 24 Hi there, the Altair 6nm ULTRA DualBand 2" Certified filters are ready to ship. You get a test report with every certified filter. The Bandwidth at FHWM for Oiii is 6nm with 93% transmission, and the FWHM for Ha is 5.5nm with 93% transmission. Tolerances are 0.5nm and 0.5% respectively. To say this batch turned out beautifully is an understatement! Ordering overseas: We offer worldwide shipping with DHL Express tracked and insured courier. 20% UK VAT sales tax does not apply to overseas orders. To find out the total cost with shipping, add the product to your basket, and choose your destination country on checkout. Enjoy! 1 Quote Link to comment Share on other sites More sharing options...
