The Starlight Xpress Lodestar X2 is the latest and most sensitive compact autoguider on the market, featuring a full sized RJ12 autoguider port and the Sony ICX829AL sensor. 

Introducing the Starlight Xpress Lodestar X2

For years, the original Lodestar guider had been held in the highest regard as the best autoguider on the market. As good at it was, the proprietary connector for the Lodestar’s autoguider cable was something of a mechanical weak link. The innovative minds at Starlight Xpress, therefore, took the opportunity to remove that weak link and make the Lodestar even more sensitive. The result is the Starlight Xpress Lodestar X2, the new best autoguider on the market.

Key Features:

Big things can come in small packages, and the Lodestar X2 CCD is no exception. This compact guide camera is packed full of great features:

  • Only 1.25 inches in diameter — allows it to drop neatly into your 1.25-inch eyepiece holder with no additional adaptors required.
  • A large imaging area (6.45mm x 4.75mm) gives you a wide field of view to find a suitable guide star.
  • Sensitivity is key, and with an impressive 77% QE, and large pixels, the Lodestar X2 just sucks up those photons. Combined with the incredibly low noise of the Lodestar X2, finding a guide star has just become even easier.
  • The full-size RJ12 Autoguider Port means there’s no need to run extra cables from your computer to control your mount corrections.
  • Powered by the USB of your computer, the Lodestar CCD sources power easily, so there’s no need to carry an extra power supply with you. That’s one less thing to forget when you are on your way to the Star Party.
  • The compact and solid aluminum construction means the Lodestar guide camera can endure just about anything you throw at it.

Great guidescope! Very sensitive. I use an OAG and have no issues finding quality stars for guiding. Easy to use.

I found a technical reason to change my order to an Ultrastar. I made a single call and everything was handled. Looking forward to its arrival soon!

This autoguider replaced my Starshoot Autoguider - it is much more sensitive and works extremely well with PHD2 (sutoguider software)

The Lodestar was shipped the morning after I ordered it and they were very accommodating when I requested a special method of shipment. I am currently on a business trip and have not even seen the item yet, but it was delivered exactly as requested. The price was also $20 cheaper than anyone else. I will definitely use them again.
