Thanks Samir for the very interesting images. How did you get images of 5 min exposure times without the stars "streaking" (except the one with full exposure to mid-histogram)?Thanks again,Andrew[a href=\"index.php?act=findpost&pid=68826\"][{POST_SNAPBACK}][/a]

I used an astro tracking mount, complete with an autoguider (a CCD camera that checks a star's position every couple of seconds and corrects the mount's tracking):[{POST_SNAPBACK}][/a]
