Product Description

Shelyak Watec 120N+ PAL Camera and 1.25" Adapter


Lhires III or eShel spectrograph require a guiding camera. If a standard webcam or video camera would work on bright objects, we found the Watec 120N+ to be very efficient:

  • for very faint targets
  • for more efficient autoguiding


Watec 120N+ camera is ideal for guiding and is now used by numerous astronomers.

  • video mode: allow you to connect a video screen close to your telescope for exemple to assist in pointing
  • exceptionnal sensibility for this price range
  • exposure time from 1/2000 to about 10s environ (256 frames) in loop


Watec 120N+ is also a great educational tool: project the video signal on a large screen during your public outreach; most bright objects are available with standard amateur size telescope!
