A closeup of Altair in Altair, taken in moonlight, with the 130mm f/6 apo refractor with the Hotech field flattener. Moonlight added the blue sky background. This is a stack of three 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 equally matched white headlight double star Theta Sepentis, or Alya, in Serpens. This is a stack of 11 x 30-second unguided exposures with the Celestron C9.25 SCT at f/10 and Canon 6D MkII at ISO 1600. Taken May 29, 2019.
Arcturus in summer twilight, in early July 2018, shot with the 130mm Astro-Physics refractor at f/6 and Canon 6D MkII. A stack of 3 x 4-minute exposures at ISO 800. Diffraction spikes added with Astronomy Tools actions.
