[Leica] Tested long exposure on the night sky last night - Howard

Eppur si muove ;-)

We may not perceive the tracks just because the FL is so short, and the sensor doesn’t record the jump from a pixel to the next one ???

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 :-)
