Hi there

The newAltair 6nm ULTRA DualBand 2" Certified filters are ready to ship worldwide.

You get a spectrographic test report with every certified filter. 

This batch turned out very nicely indeed! Our new V2 coating process is really showing it's potential!

Based on testing of 90 filters so far, we have an average Bandwidth of 6nm FHWM for Oiii / 93% peak transmission and the FWHM for Ha is 5.5nm with 93% transmission. Tolerances are 0.5nm and 0.5% respectively.

I'm very happy with this production run, and I hope you agree we have kept the price very reasonable with regards to performance.

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.

Clear skies!
