I'm looking to try shooting this one again in mono once it gets a little higher. Such a pretty target.
Yep. Fog on the coast is always a challenge, even when it stays "out" it typically reforms after midnight when the temp hits the dew point. My imaging window is tight too, so 4 hours is typically a great run for me as well. Of course, in spite of the challenges at night I always remind myself I can be walking on the beach in 15 minutesSTEVE333 wrote: ↑Tue Oct 05, 2021 3:35 am
Thanks. I believe this is the most time I've gotten on any target. It was very gratifying to see the reduction in noise.
My setup only allows for capturing data from about 30 degrees above the Eastern horizon up to the zenith. After that my mobile home or the driveway awning block the sky. So 4 hours in one night is about the best that can be done. Being a coastal town the fog is always a potential show stopper. The 16 hours was 12 hours from last year (4 Ha, 4 O3, and 4 S2) and 4 hours of Ha from this year. You may have similar fog problems in San Diego if you live close to the coast.
