    • Altair 6nm Dual Band filters now available in 1.25" size

      Altair Certified 6nm ULTRA DualBand filters available in 1.25" size

      nickaltair posted a topic in Sponsor announcements and offers - Altair Astro,

      The popular Altair 6nm Dual Band filters are now available in 1.25" size.
       
      Each filter has a unique spectrographic report and matching serial number - so you aren't playing "filter roulette" any more. Every filter is on-band and within tolerance.
       
      Just like with Altair refractors, we offer total quality assurance - and now we've pioneered QC with filters too.
       
      There are two versions, the Ha/Oii and Sii/Oiii, available either individually, or as a combo. With the combo, you can image with a true Hubble palette, colour camera - and gain twice the amount of Oiii data in only sessions. 
       
      Enjoy!

    • Altair Hypercam 585C in stock

      Altair Hypercam 585C in stock

      nickaltair posted a topic in Sponsor announcements and offers - Altair Astro,

      Hi there, the Altair Hypercam 585C Fan Cooled Camera is in stock.
       
      This camera really does it all, for a very good price. 
       
      - The latest generation Sony IMX585 STARVIS II BSI Sensor makes long exposure deepsky astrophotography, easy with minimal post processing.
      - The STARVIS II level sensitivity allows easy video astronomy and the low read noise is ideal planetary imaging.
      - The fast frame rate with USB3.0 is a pleasure for lunar and planetary imaging.
      - Fan cooling allows for low noise deepsky imaging.
      - The Altair 585C will accept C-Mount lenses with the included C-Mount adaptor, making it a great Allsky camera.
      - Compatible with NINA, APT, SharpCap and other software through the ASCOM driver.

      Imaging the sun (with a safe solar filter) is very rewarding because no two solar images are the same.
