10-C Spectrograph

Our 10-C spectrograph is the first one produced (serial number 0) of the popular 10-C spectrographs made by Optomechanics Research of Vail, AZ. It has some differences from the popular production model but it performs in a similar manner.

History

• Imaging Camera:

  • Originally the 10-C was build for a standard camera body and film.

  • Later it was upgraded to using an SBIG ST-8 camera to image the spectrum.

  • In 2016 the camera was upgraded to an SBIG STT-1603ME

    • Kodak KAF-1600 chip (UV coated)

      • 1536x1024 pixels (9 micron square)

      • Gain = 1.28

    • -50 C cooling

• In 2013 we had Ron Hillard build a long-slit for us. The length is a few arc minutes long.

• In 2016 we replaced the telescope mating collar (the threads had worn on the old one).
