STX to TGA Conversion: FAQ

What are STX files?

STX files represent RAW images created with SBIG CCD cameras. They are part of a group of formats known as Santa Barbara Instruments Astronomical Images, also including ST5, ST6, ST7 and ST8. Apart from astronomy, SBIG cameras can also be used in medical imaging, color photometry and a few other scientific and industrial sectors. All formats in the group are considered specialized and rare, so opening STX files might be possible only after conversion to more widely available extensions.

What are TGA files?

The TGA (Truevision Graphics Adapter) format, also known as Truevision TGA or TARGA, is a bitmap file containing raster graphics and was initially associated with TARGA and VISTA boards. TGA files can be used on DOS, Windows and Mac OS X platforms for storing and transferring deep-pixel images. They support a color range of up to 24 bits and an 8-bit alpha channel.
