Orion (50mm EOS Ra).jpg
Orion on January 2, 2020 in the moonlight from a first quarter Moon, with orange Betelgeuse much dimmer than usual, a little brighter than Bellatrix at right.
This is a single 4-minute exposure with the 50mm Sigma lens at f/2.8 and Canon EOS Ra at ISO 400 and through the NISI Natural Night filter, and on the iOptron SkyGuider Pro tracker. Haze moving in added the natural star glows (no filter was needed to add those) and the haze ruined subsequent images in the set. So this is from only one exposure but serves to record the brightness of Betelgeuse this night. Gradient Xterminator filter used to even out the sky illumination.
