, Posa B f/3.5, ISO 100, tripod.

Singola posa da 8 minuti ripresa dal terrazzo di casa, quindi in pieno inquinamento luminoso. Scattata per valutare la bontà o meno dell'ultima modifica fatta al codice che comanda arduino. Con questa modifica riesco a variare la velocità dell'inseguitore in modo da "correggere" l'errore periodico del sistema. A otto minuti si inizia a vedere un elongazione delle stelle, sintomo di una non perfetta velocità media di inseguimento e magari un non preciso puntamento alla polare. Tuttavia si nota che sono riuscito ad attenuare l'errore periodico che mi portava ad avere stelle "ovalizzate" già ad un minuto di ripresa. A spero presto con altre riprese, magari da posti più bui. Ciao ;)
