A simple focus assistant for astro photograph using HFD calculation. This tool is inspired by a similar project astrofocuser by thx8411. And the algorithms is base on OpenSkyImager by Giampiero Spezzano. Thank you all.
- Install gtk+2.0 dev package
- make
HFD Focuser will capture a region on the left of it's window and calculate the HFD value .The value will be plot and displayed. Just put a star on the left of the window so you can see it in liveview section , then adjust your lens/telescope/focuser to get a minimal value of HFD, you can get a best focus .
Sorry for my poor English and hope you like the little tool .
