New Altair 3nm ULTRA Narrowband filters are in stock.

 

Another Altair first - each filter has an individual test report.

 

Very deep OD blocking make these filters able to support deepsky imaging with a full moon, in the city. In fact, the images below were taken in London this summer.

 

I've added some star tests with Altair 80mm F6 Triplet APO running at F4.8 with Planostar 0.8x reducer. They were kindly sent to me by customer Ryan Harris, a Beta tester who has had them for some time, and a member of the Altair Facebook group. You can check out his images in the group.
