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.
- 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.
- Spectral Response: QE max at 620nM (~77%), 45% at 400nM and 770nM
- Readout Noise: Less than 10 electrons RMS - typically only 6 electrons
- Full-well capacity: Greater than 50,000 e- (unbinned)
- Anti-blooming: Overload margin greater than 1000x
- Dark current: Dark frame saturation time greater than 1 hour. Less than 0.1 electrons/second @ + 10C ambient
- Data format: 16 bits
- System gain: 0.4 electrons per ADU
- Computer Interface: Built-in USB 2.0 compatible interface
- Image download time: Typically 0.2 seconds at full resolution using USB 2.0
- Power requirements: USB powered
- Cooling system: Ambient air cooling
- Size: 32 x 86mm black anodized aluminium barrel with 1 x 32tpi mount thread at the CCD window end & input/output plugs at rear
- Weight: approx. 85 g (3 oz.)

I bought this camera to replace a SBIG ST-I camera that had stopped working. I can take images with this camera, but I can't calibrate the guider. It simply won't move the telescope to guide. I've not been able to find any documentation on setting up the camera as a guider. Right now, I'm very disappointed. Looks like I'll need to buy another ST-I.
Starlight Xpress Lodestar X2 Autoguider
Lodestar X2 was setup through MaxImDL. Calibrated the Autoguider with a star in Andromeda, got a perfect L shape centered on the star. I use CCDCOMMANDER to image and guide. Guider worked perfectly, got round stars in image of NGC891. Guider finds guide stars in less than 5 seconds. Guider does not require dark frames and is devoid of noise in its image. Setup and calibration took about 20 minutes. I recommend purchase of this Autoguider from OPT.
Starlight Xpress Lodestar X2
The X2 seems to be greatly improved from the older Lodestar. The connection port is not flimsy.
Great Guide camera
My previous guide cam was a QHY5L-II and the X2 is hands down better. Using an OAG it was hard finding some guide stars that had enough SNR for PHD2 to track. This camera made tracking some of the faintest stars better.
Lodestar X2 Is Outstanding OPT Not So Much Anymore
The Lodestar X2 is an outstanding guide camera, especially for off axis guiding. Small, light and very sensitive and makes guide stars just literally jump out. As far as OPT is concerned. Don't know what's going on with them anymore. They used to be outstanding. Very friendly and prompt. Not so much anymore. For the life of me can't figure how it could possibly take a full week to walk to a shelf pick up one little box and put a shipping label on it. Called to ask about it and the person I talked was not overly friendly. Was also informed that they had done away with the customer awards program that was supposed to be a lifetime deal. My next purchase is going to be a premium GEM mount but thinking it won't necessarily be from OPT. Disappointing that it has gone this direction I always enjoyed dealing with OPT in the past.
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.
