Saturn imaged 28 August 2021. Scope is Starmaster hybrid truss with 14.5" f4.3 Zambuto primary to Antares 1/20-wave secondary through Siebert 45mm Binoviewer to ZWO ASI294 MC Pro camera on one side, eyepiece on other. Best of several 30-second SER videos captured in SharpCap, 30% best frames selected in AutoStakkert, sharpened in Registax 6. Digital Photo Professional used to correct for atmospheric color dispersion, and histo-stretch to see Dione and Tethys. Enceladus also showed up but when adjusting black level it faded into the background, It would be centered just above the other 2 moons.
