Light Source for Point source fibers - telescope

Click For Summary
SUMMARY

The discussion centers on the types of light sources suitable for single point source or artificial star calibration in telescopes. Participants confirm that LEDs, particularly green ones, are effective for this purpose. Additionally, they mention the availability of commercial light sources designed specifically for telescope calibration. The link provided leads to a resource for building an artificial star using a point source.

PREREQUISITES
  • Understanding of telescope calibration techniques
  • Familiarity with fiber optics in astronomy
  • Knowledge of LED specifications and applications
  • Basic principles of artificial star creation
NEXT STEPS
  • Research commercial light sources for telescope calibration
  • Explore the specifications of green LEDs for optical applications
  • Learn about fiber optics integration in astronomical setups
  • Investigate DIY methods for creating artificial stars
USEFUL FOR

Astronomers, telescope operators, and hobbyists interested in enhancing their calibration techniques using artificial stars.

Hi. I am wondering what kind of light sources are used if one is using a fiber to do a single point source or artificial star calibration on a telescope? Any commercial ones can do if anyone knows one.

I've heard that LED's can be used. I would use a green one of course.
