Nightlight

Nightlight is a new desktop application whose aim is to bring a modern interface to FITS files with the polish and design people expect from applications they use every day. By making it a native Macintosh application, one is able to leverage cutting edge frameworks that enable GPU acceleration, multithreading, interactive touch interfaces, real-time image processing, desktop metadata indexing, and more. FITS (flexible image transport system) is the standard file format used by professional astronomers. Nightlight is designed to answer the question, "What is in this FITS file?" without requiring a line of code.

Features:

• View the structure of a FITS file at a glance
• Displays all image and table HDUs
• Thumbnail view of all HDUs
• Metadata "card" view for table columns
• Supports an unlimited number of table rows and columns
• Inspector panels for image views
• Supports WCS (world coordinate system) overlays for ten coordinate systems
• Pinch and zoom image magnification for trackpad users
• FITS headers displayed in a floating panel
• Nightlight uses Spotlight to find all the FITS files on your computer for you

• Nightlight now supports macOS 10.10-10.12.
• 2D images that look like 2D spectra now displayed as plots in thumbnail views.
• fitsverify now called as an external process (now won’t crash Nightlight).
• Better handling/display of edge cases of several data types.
• Fixed display of tool tips in table views.
• Null values now correctly displayed in table column card views.
• Numerous small user interface fixes.
