Product Details

  • Borrowing from the same compact concept as the Starlight Xpress Lodestar, the Ultrastar is highly sensitive miniature CCD camera with both guiding and imaging capabilities. Low internal noise and ease of use make the Ultrastar an exceptional primary camera choice for the beginning astrophotograher and a premium guide camera for the intermediate to advanced user.

    Perhaps the Ultrastar's greatest feature is the ability to stack images while shooting. When used in conjunction with Starlight LIVE software, the Ultrastar will provide a build-as-you-go imaging experience. Rich detail is exposed when short exposures are combined over the course of the imaging session making it a great choice for outreach and educational situations where students and participants can see their final imaging results with almost instant satisfaction, without the tedium of post-processing. While the camera is uncooled, the internal noise levels are very low. Warm pixels are simply removed by applying hot pixel filters, stacking dithered images or using conventional dark frame subtraction. Starlight Xpress' original image processing software is included to allow for as much fine-tuning as you please.


    The Ultrastar is extremely compact and perfect for grab-and-go imaging set ups. If you love to travel, camp or hike to more remote locations for imaging or own a very lightweight setup this is the camera for you! Powered by mini-USB which connects through the rear of the camera, the Ultrastar draws less than 200mA. Leave the extra power supply at home! The camera is a featherweight at only 3 ounces. It will never bog down your gear on even the most lightweight of imaging set-ups.


    For those seeking a premium guide camera, the Ultrastar provides nearly twice the imaging area of the Lodestar. The Sony ExView 2/3-inch format CCD chip also provides progressive scanning and better dark current performance.


    Additional Key Features:

    • 1.25-inch diameter allows the Ultrastar to drop neatly into your 1.25-inch eyepiece holder, no extra adapters needed.
    • Large imaging area: A 8.98 mm x 6.71 mm imaging area gives you ample space for wide field imaging of galaxies, nebulae and for finding a guide star with ease.
    • Impressive 75-percent QE, the Sony ExView ICX825AL Monochrome Grade 1 CCD chip has large 6.45 micron square pixels to quickly and effectively gather light.
    • Verical anti-blooming keeps light from spilling over into unwanted pixels.
    • Full size RJ12 Autoguider port. Eliminates extra cables from your computer to your mount for mount corrections.
    • USB 2.0 powered. 2 frame per second at full resolution download speed.
    • Aluminum construction for durability.

      Works well as a guider

      Using this with SkyX.Still learning to adjust the driver settings to get maximum performance. The large image size makes this a camera with many possibilities. Good sensitivity even with a 30mm QHY guide scope. So far this camera is reliable guiding a CEM25p. I chose this camera to replace an aging SBIG STi, as the guider interface seems to be more reliable than other cameras like QHY or ZWO, which I have had problems with. The camera is expensive, but you get what you pay for. I have never had a problem with 8 different SBIG and Starlight cameras. I have had various problems with 50% of the 6 ZWO / QHY cameras I have had.

      Ultrastar mono guider

      This is by far the best guide camera I have used. Big chip with big 6um pixels. The driver is excellent as well. Used in The SKY X Pro.
