Drizzling
The following image shall demonstrate, how drizzling can enhance details in planetary imaging. Drizzling reduces the SNR, so it is mandatory,
to use more frames for stacking. Here, a total of six videos had been concatenated and then stacked with 3x drizzling.Due to the high amount
of frames, the SNR of the final image is still in a reasonable range.

The 2023 Saturn opposition
The 2023 Saturn opposition showed Saturn a little bit higher in declination, so that a photographic approach to the ringed planet made
sense since several years, where Saturn had its lowest declination values.
