No single item in recent memory has had more of an impact on planetary imaging than RegiStax
, developed by Dutch amateur Cor Berrevoets. By aligning and stacking multiple images obtained with inexpensive webcams and backyard telescopes, the program can create images that surpass even the finest ground-based views made a few years ago at professional observatories. In October 2006 Berrevoets released his much-awaited RegiStax 4
. Among its newest enhancements is the ability to use multiple alignment points in an image, which greatly improves the software’s performance with solar and lunar images. Is it still a bargain? As freeware, how can it not be!
