APT - Astro Photography Tool
(released on 2016/11/10)
(next version in January 2017)
APT stands for "Astro Photography Tool" and it is like Swiss army knife for your astro imaging sessions.
No matter what camera you use - Canon EOS DSLR or CCD, APT has the right tool for planning, collimating, aligning, focusing, framing, controlling,
imaging, synchronizing, analyzing and monitoring. All its features are packed in an easy and comfortable to use interface with design that had no alternative back in 2009 when
it was released. Since then APT is constantly being improved and refined by the real experience of many astro photographers from all over the world and by author's
own experience. Currently APT works on MS Windows XP, 7, 8, 8.1 and 10.
