Hi All,
I came across a mention of such a software on the Starizona Imaging guide.

Does anyone know what software this is? It looks like a accurate way of focusing using a bright star. The software essentially works on the intensity of the brightest pixel and when this count is high it is a good indication of accurate focus.
Regards
