STX to GIF 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 GIF files?

GIF (Graphics Interchange Format) files are widely popular due to their ability to store animations and images in a relatively small size. Their compression algorithm implies the use of a limited color range (up to 256 colors), which means GIF files are great for storing static and animated images of a small size — like logos, icons or avatars, especially if you plan to transfer them or upload them online. GIF images, however, are usually not suitable for high-quality image rendering or printing.
