A closeup of Pollux in Gemini, taken in moonlight, with the 130mm f/6 apo refractor.

This is a stack of six 2-minute exposures and three 30-second exposures to reduce the core brilliance, with the short exposures blended in with a luminosity mask. All with the Canon 6D MkII at ISO 800. The diffraction spikes were added with Astronomy Tools Photoshop actions.
