About this product
The new Starlight Xpress Superstar is essentially a higher resolution version of the hugely successful Starlight Xpress Lodestar making it an excellent choice for guiding through short focal length refractors.
Primarily intended as a high performance guider but will also serves as an electronic finder and planetary imaging camera!
Suitable for most mounts with a standard autoguider input.
As small as a 1.25" eyepiece!
Note: The new Starlight Xpress Superstar has good sensitivity but where high sensitivity is priority (when using long focal length telescopes and off-axis-guiders) the lower resolution Starlight Xpress Lodestar is still 'top dog'!

Over the last 17 years I've tried various cameras for autoguiding, with varied success.
I bought this camera, after getting fed up struggling to find guide stars at lower magnitudes. This camera has solved that problem for me completely. It can stay attached to my ST-80 without any problems. Starting up PHD2, shows stars in any random field of view that I happen to choose so far. When using other cameras, I was struggling to find anything dimmer than the trapezium. Wasted loads of time and effort on other methods. Would highly recommend this camera for guiding. Actually, it's better than my imaging camera!
