Mit meinem Teleskop habe ich abgebildet, wie Saturn und Titan hinter dem Mond vorbeiziehen

Mir wurde klar, dass ich diese Aufnahme nie auf diesem Sub gepostet hatte, und da es eine meiner besten ist, dachte ich, warum nicht. Es wurden einige neue Verarbeitungstechniken für die Saturnbedeckung im September 2024 (17.09.2024) eingeführt und einige Schärfungs- und Leuchteffekte hinzugefügt. Ausrüstung: Celestron 5SE, ASI294MC, 2x Barlow. Aufnahme: 1 Minute gestapelte Monddaten, 7 Minuten gestapelte Saturndaten, sogar live in einem Video aufgezeichnet, das ich ebenfalls eingefügt und gestapelt habe, um mehr Details hervorzuheben. Die Wolken zogen sooo bald nach der Bedeckung auf, dass ich begeistert war, es mir schon vorher vorstellen zu können! Wirklich zufrieden mit dem Ergebnis.

@elliots Only if there is some kind of triage on what cars really need to be on the road, and there are a LOT fewer of them.

@scott @elliots @lahosken It is certainly not Golden Gate Park. I'd think somewhere on the coast in the South East corner of the city

@LevZadov Approximately one-third of San Francisco's residents do not drive, and at an absolute minimum, we deserve a third of the resources - including street space, infrastructure, and money.  The war against pedestrians must be challenged, however much those with privileged subsidies and convenience may not like it.
