Description

A

Unfortunately I could only use 57 of over 300 frames because of wind and low stratus.

Leider konnte ich wegen Wind und Hochnebel nur 57 von über 300 frames nutzen.

Re-did on 22nd and - under better conditions (no wind or low stratus) - on 23rd of February before moonrise and used the best 132 of more than 400 lights. Now I'm quite satisfied!

Führte Aufnahmen am 22. Februar und - unter besseren Bedingungen (kein Wind oder Hochnebel) - am 23. Februar vor Mondaufgang durch und benutzte die besten 132 von insgesamt mehr als 400 lights. Jetzt bin ich halbwegs zufrieden! :-))
