APT User Guide - Bahtinov Aid

Astro Photography Tool Video User Guide Bahtinov Aid The Bahtinov Aid uses licensed technology developed by Neils Noordhoek - the very same technology built into the famous Bahtinov Grabber. It allows achieving precise focus using a Bahtinov mask making sub-pixel analysis of the spikes. I may be wrong, but I really do think using a Bahtinov mask is the most accurate way to achieve focus. Thankfully some semi-clear skies allowed me to get in & do this under live conditions which is needed to demonstrate Bahtinov Aid fully.
