Plato/Apennines 2-panel mosaic, 80% waxing, UV/IR-cut/L + Wratten #25 red filters
Posted: Thu Nov 18, 2021 12:33 pm
Captured 14th November 2021, around 20:20. Elevation 30°.
Celestron AVX mount, Celestron C8 SCT, 0.63x reducer, Skyris 618m CCD camera, UV/IR-cut /L + Wratten #25 red filters to mitigate brightness.
2 panels, each 7200 frames @120fps (60s). SER MONO8 640x480, gain 300 (out of 1000), exp=3ms. Histogram saturation 60%.
SC 4, Autostakkert!3 best 30% stacked with drizzle 1.5, Microsoft Image Composite Editor, Registax (wavelets 2, 1, 3 and brightness, contrast, gamma).
This was part of a 1 hour capture session which resulted in 25 SER videos totalling 50Gb. Here is a typical capture in progress from the session:
Filters tried were IR685, UV/IR-cut /L, Wratten #25 red including combinations. With the moon crossing the meridian, the UV/IR & #25 red seemed the best combination for handling the brightness and giving good contrast.
