Designed for Windows, it remains a popular choice for photographers who prefer a stable, legacy interface for aligning and stacking deep-sky images. Why Version 3.3.2?
Released as a critical bug fix for version 3.3.1, the 3.3.2 update addressed stability issues identified by the astrophotography community.
