Reviews

• http://www.dansdata.com/astroscan.htm
  • 200x in theory
  • Edmunds recommends only 35x because of the aiming problem
• http://www.cloudynights.com/documents/astroscan.pdf
  • 40-45x max magnification
• http://irwincur.tripod.com/edmund_astroscan.htm
  • Max power ~ 130x

  • Still, 30X is just enough to make out the rings of Saturn and cloud belts on Jupiter
