About Starlight Xpress Ultrastar
How does the Ultrastar Mini CCD Guiding/Imaging Monochrome Camera, with its high-quality 1392x1040 resolution, revolutionize astrophotography As an advanced iteration of the 'Superstar' guide camera, the Ultrastar boasts a CCD chip with 70% more area, and a Quantum Efficiency (QE) that peaks at an impressive 75%. These innovative features enhance the Ultrastar's performance, making it an exceptional choice for both guiding and imaging in astronomy.
This durable and compact camera is particularly adept at 'Live Viewing' mode, a feature that sets it apart in the realm of astrophotography equipment. The Ultrastar's compatibility with the upgraded 'Starlight Live' program, an evolution of Paul Shears' user-friendly 'Lodestar Live', allows for seamless control in Live view. Moreover, it can color convert and stack images from the single-shot color versions of these cameras, offering a comprehensive solution for capturing the night sky's breathtaking detail.
Whether you're a seasoned astronomer or a budding stargazer, the Ultrastar Mini CCD Guiding/Imaging Monochrome Camera is a reliable tool for your celestial explorations.
Starlight Xpress Ultrastar Features
- Added multi-spectrum stacking capability. Color channels can be masked during stacking process
- Added ability to select individual color channels for display (multi-spectrum)
- Display Processing 'Reset' button now resets all color channels to defaults as this is more intuitive for multi-spectrum
- Added button on Image Export tab to save the current stacked image in FITS format (prior to display processing - i.e. the current raw stack)
- Added color channel mask to the automatically generated filename when exporting raw FITS files
- Added command line parameter '-load-image-rggb' to permit loading of Bayer RGGB encoded images. This can be used to later load and display a FITS file saved using the save current stacked image to FITS file feature (when image was color)
- Image repeat dialog display mirrors the main display window, including any zoom applied plus overlays
- Disable image registration during stacking by setting Max Displacement to 0 (i.e. images are just stacked without any alignment)
- Improvements to star pattern matching algorithm to increase robustness of correspondence (especially with Ultrastar images)
- Enhancements to star extraction algorithm
- On key frames, image is divided into 4x4 grid and the 3 brightest stars are selected from each grid to limit the number of stars to be matched
- When matching stars, the corresponding star is searched for inside a bounding area defined by Max Displacement plus 10% with respect to the position of the keyframe star. All candidates within this area are then used for correspondence matching
- Fixed undo bug that caused exposure number to keep decrementing when 'undo last' is clicked after an undo is applied
- Added keyboard shortcuts to zoom and pan the image display
- Added keyboard shortcuts for the display processing tab. One of the functions (i.e. black level, white level) is selected via the numeric keys and then this can be modified by other keys to decrement or increment the value instead of using the UI slider control
- Multiple performance enhancements to the display processing algorithms. These now use multiple CPU cores during processing. The more cores the faster the algorithms run
