ALTAIR nickaltair Posted July 26 ALTAIR Share Posted July 26 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.

TareqPhoto Posted Thursday at 04:18 Share Posted Thursday at 04:18 I am just planning to buy SII 3nm 2" and a dual band filter of 3nm as well, i already have Ha 3nm from another brand and with a dual band i don't need to buy OIII, i have OIII 3nm 1.25" from Chroma for smaller sensor, so i must rearrange my priority better.
