This is one of our favourite cameras in the range due to it's versatility, amazing tonal range, and nice square 15x15mm image frame offered by the Kodak KAI4021 sensor, which makes full use of the image circle vs. sensor surface area on any telescope. We really like this camera!

Get in touch for special price when purchased with an Altair Astro telescope.

The relatively large 7.4 micron pixels make the Trius 814 CCD camera very sensitive indeed, and well suited to medium focal length scopes from 700mm onwards, such as the Altair Wave Series 102mm APO refractor (see the product thumbnail gallery for results), the Wave Series 115, and of course the Wave Series 130mm, and it will perform well with these telescopes. It will also perform well with Altair Ritchey Cretiens from 6-8" and even 10" versions, though one is straying into the larger pixel sizes offered by the Trius 25, 26, 35 and 36 range at these larger apertures and focal lengths due to the larger airy disc.

Please choose a monochrome or one-shot colour version in the dropdown menu before ordering.

Crescent Nebula Image Altair 102 715 Super ED Triplet APO

Above is a full frame image of the Crescent nebula in Cygnus taken with the Altair 102/715 Super ED Triplet APO and Planostar field flattener by Phil Shepherd, at the Kelling Heath Starparty in Norfolk. Exposure times were 6x600s in Ha, SII & OIII wavelengths using a filter wheel, with an Starlight Xpress SXV-H16 CCD camera. Click on the image for the full resolution shot. Colour correction is excellent, and there is no false colour fringing evident whatsoever. The stars are tight, round and concentrated points of light right to the edge of the frame due to the 1.0x Altair Planostar field flattener. Even the hottest bluest stars exhibit in incredibly small blue halo - less or equal to than telescopes costing many thousands of pounds more, which shows off the blue colur correction of a well corrected FPL53 triplet Super APO.

Trius Highlights:

  • Back focal length only 17mm +/-1mm.
  • The CCD sensor can be adjusted in tilt from the front of the camera.
  • High speed USB 2.0 interface for approx. 2.5 second downloads at full resolution (somewhat computer dependent).
  • Built-in autoguider interface and output - compatible with our optional dedicated external guide cameras.
  • 3x powered USB ports for guider and filter wheel control
  • Single USB cable control for all features for less cables in use overall

Dr Dietmar Hager has tested and reviewed the SXVF-H16. His conclusions can be found at www.stargazer-observatory.com/reportsCCD-h16-engl.htm

Major features:

  • Large, high resolution Kodak CCD chip, with 4,194,304 x 7.4uM square pixels in a 15.15 x 15.15mm array.
  • Low dark signal - Dark frames not necessary for most of the brighter deep sky objects.
  • Anti-blooming with minimal effect on linearity and no lost active area.
  • Built-in super high speed USB 2.0 interface for approx. 2.5 second downloads.
  • High sensitivity, 55% QE at peak (green light).
  • Back focal distance 17mm +/- 1mm.
  • Built-in autoguider interface and output - compatible with the optional dedicated external guide camera.
  • Built-in dual serial ports for accessory control - directly drive filter wheels, GOTO 'scopes etc.
  • Single USB cable control for all features - get rid of that dangerous cable tangle!
  • Only ONE computer needed to control all of the devices and functions.
  • Very low power consumption. Less than 1.0 amps at 12v DC - 12VA at 110v or 240v AC.
  • Compact and lightweight - only 75mm in diameter x 100mm long - less than 500 grams load on the 'scope!
