BackyardEOS is a great addition to my astrophotography toolkit. It makes focusing on distant objects a snap with easy FWHM(Full Width Half Max) and several other modes. I’ve tried a few different imaging software aimed at astrophotography and this has been the easiest/best. However it does come with a $50 price tag but its worth every cent to me when I see the beautiful pictures. Give their trial a shot and see if it is the software for you.
