Starlight Xpress LodeStar X2
Stand-alone Autoguider - The Best is now even Better!
Exceptionally high sensitiviy, incredibly low noise, minature, USB2.0 imaging/autoguiding camera
  images will be available soon  

For years, the Lodestar has been held in the highest regard as being the best autoguider on the market. The innovative minds at Starlight Xpress have been trying to improve on the iconic Lodestar since it’s conception; however, this has proved to be very difficult to achieve - until now that is.

Introducing the Lodestar X2; the latest and most sensitive compact guide camera from Starlight Xpress.
Big things can come in small packages and the Lodestar X2, really is no exception. This compact guide camera is packed full of great features:
  • ONLY 1¼” in diameter allows it to drop neatly into your 1¼” eyepiece holder - no additional adaptors required.
  • Large Imaging Area (6.45mm x 4.75mm) giving you a wide field of view to find a suitable guide star.
  • Sensitivity - with an impressive 77% QE, and large pixels, the Lodestar X2 just sucks up those photons. Sensitivity is key, but combined with the incredibly low noise of the Lodestar X2, finding a guide star has just become even easier.
  • ‘Full size RJ12’ Autoguider Port - No need to run extra cables from your computer to control your mount corrections.
  • Powered by the USB of your computer so no need to carry an extra power supply with you - one less thing to forget when you are on your way to the Star Party.
  • Compact and solid aluminium contruction.
