Jul 9, 2015 at 6:15 comment added Noldor130884 I totally agree. Hours if you want FULL arches... And blur in the tree? Where?
Jul 6, 2015 at 15:07 comment added user13451 A 3h duration star trail would have each star tracing out 1/8th of a circle (45 degrees). The arc of each trail is clearly much less than 45 degrees.
Jul 6, 2015 at 14:30 comment added Nicolas Tenorio in the picture you can see blur in the tree, and 5 min? for that movement? i don't think so "Typical exposure times for a star trail range from 15 minutes to several hours". link
Jul 6, 2015 at 5:44 comment added Noldor130884 Absolutely not. With a minimum of wind you would have a picture with blurry tree and so on. With that stars' movement I don't believe that the exposure was more than 5 minutes for the sky
