A closeup of Capella in Auriga, 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.
The close double star Castor, or Alpha Geminorum, in Gemini, in a stack of frames from a webcam (Philips TouCam) from 2005 with the C8.
A closeup of Castor in Gemini, taken in moonlight, with the 130mm f/6 apo refractor. While this is a double star the separation is too tight for the stars to be resolved here. 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.
