Clavius - best 1% of 20,000 frames
Posted: Tue May 24, 2022 2:51 pm
Captured May 2022, ~75% waxing moon. Captured at 21:45 with moon approaching the meridian. Hampered by high, thin cloud - see the Autostakkert quality graph.
Celestron AVX Mount, Celestron C8 SCT, UV/IR cut filter, QHY5LII-M camera, JMI motorised focuser.
20,000 frames @ 46fps, 800x600, MONO8, SER, exposure=2.5ms, gain=10.
Sharpcap 4, Autostakkert!3, Registax 6, Faststone Image Viewer.
This capture took a big hit with high, thin cloud - see the Quality graph. By limiting to 1% of the 20,000 frames (~200 frames), the quality was 70% or better (no point stacking bad frames). At 2% of frames, the quality had dropped to around 60%. Stacked with drizzle 1.5.
Registax for wavelets, brightness, contrast, gamma. I processed the AS!3 _conf file which is sharpened and applied conservative wavelet settings.
Faststone Image Viewer was used to crop and flip the image.
