Although I was using a tripod as you may imagine, I had left the IOS on, that could be another reason why. There was absolutely no wind and the foliage seems to prove it. OTT 10mm means 15mm in Leica world, but it doesn?t modify the result ... I?ll try a longer lens at the earliest opportunity, say the Novoflex 400 (600 eq.) for instance, and see what I get, and report. Thanks Howard. Stay well, and vigilant :-) Amities Philippe > Le 20 oct. 2018 ? 17:04, Howard Cummer via LUG <lug at leica-users.org> a > ?crit : > > Hi Philippe, > I am surprised that you can take a 30 second exposure with a 10mm lens > and have such small star tracks.
