Focus Stars Project

Melissa, Julissa and Christina of WPCP are working on this project for a focus program routine for Stone Edge Observatory, at the request of the telescope manager.

The Focus Stars project needs these kinds of stars in a field that is about 15 arc minutes (a quarter of a degree). 

  • Stars that are near the celestial equator more or less between 0 and 20 degrees North Declination so that the telescope is pointed midway up the sky when it is facing south. 
  • Stars that are 6th magnitude but not brighter.  Remember the magnitude scale is somewhat illogical.  The stars that are brighter have a lower magnitude. So, no 5th or 4th magnitude stars, but 7th magnitude stars and dimmer are ok. This is because bright stars will saturate (fill up the pixel 'light bucket') and we won't be able to get a good bell curve profile of the starlight across all the pixels for the star, if  you did a slice across the star.)
  • No other bright stars should be in the 15 arc minute field.  That means no other stars brighter than 6th magnitude.
  • The stars cannot be double or multiple stars because the program won't be able to figure out that there are two stars there and the analysis will be mixed up.  (There would be two peaks in a double star slice.)
  • And, we need about 12 to 20 stars all the way around the celestial equator so there is one near where the telescope would point on the meridian (due south).  
  • Maybe you could make a screen shot of the planetarium program that shows any star fields that you pick out.
