Starlight Xpress Lodestar X2 Autoguider

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.

Key Features:

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:

  • 1.25" diameter allows it to drop neatly into your 1.25" eyepiece holder - no additional adapters required.
  • Large imaging area (6.45mm x 4.75mm) gives 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 there's 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 aluminum construction.

Great Guider
I am using this camera with my 80 mm guide scope, it is replacing the DSI camera that I was using, this camera is very small and lightweight but does it ever deliver. I am using it with PHD and even with the exposure set at .5 sec I get all kinds of stars. I slewed the scope over to M42 and left the exposure at .5 sec and I could not only see the 4 main stars but some of the nebulosity. This is a great camera and opt delivered it on time and packaged it nicely. Review by Ghostrunner / (Posted on 1/30/2015)

Questions & Answers

Product Questions

Is the loadstar considered a DirectX Camera?
Hi There:

Would this be compatible with a William Star 71, which I'm using both as a guidescope and a imaging scope? If so, will I need an adapter to address any back focus concerns?

Is this compatible with Maxim DL?

Thanks a lot,

Am I correct that this item ships with usb and guider cables? Are they in stock or not - the front page says they are but when added to an order it says they are not.
What kind of software is used to guide? Will it work with PHD guiding? Does it support dithering as PHD does when I use Backyard DSLR Camera control?
Will this guide camera work with PHD2 and a MacBook Pro? The PHD2 manual shows "Lodestar" (not X2) for Windows, but only the SXV in the Mac list. I can't buy this if I don't know.
How does the X2 get connected to PC and then to Drive controller ?
( I am using Losmandy 492 on GM200 and PHD )
I've read everything I can find, my X2 will arrive in 2 days.
I think the setup is .... USB to PC ... RJ12 to drive controller.
and PC then talks to drive controller thru USB / X2 / RJ12.
What is the maximum current draw, in amps, for this camera over the 5V USB connector? I want to make sure I don't overload my USB hub.
Is it possible to image AND guide at the same time?
Will this work with Losmandy G-8 and G-11 control boxes for auto guiding? Does it plug into the Losmandy manual paddle port?
The port guide is St4 supported?
