Astrophotography Glossary
Learn the terminology of planetary imaging. From stacking to wavelets, understand the concepts behind professional results.
Techniques
Combining multiple frames into a single high-quality image
Selecting only the sharpest frames from a video
Multi-scale sharpening technique for detail enhancement
Mathematical sharpening using PSF modeling
Registering frames so features overlap precisely
Imaging through the telescope eyepiece with a camera
Expanding tonal range to reveal faint detail
Contrast Limited Adaptive Histogram Equalization
Matching pixel size to telescope resolution for optimal detail capture
Super-resolution technique using sub-pixel shifts
Equipment
Cropping the sensor to increase frame rate
Number of frames captured per second
High-speed camera designed for planetary imaging
Balancing sensor amplification and light collection time
Telescope focal length divided by aperture diameter
Optical element that increases telescope magnification
Prism device that corrects rainbow fringing from atmosphere
Astronomy
Atmospheric turbulence affecting image sharpness
When a planet is closest to Earth and brightest
Angular measurement unit (1/3600 of a degree)
Numerical rating of atmospheric stability for planning captures
