The Constellation of Orion (EOS Ra 50mm SkyGuider).jpg

Add to Cart Add to Lightbox Download
A portrait of Orion and the northern winter Milky Way, on a February night, 2020. The Orion Nebula is the bright, overexposed pink glow below the Belt of Orion, while the curving arc of red is Barnard’s Loop, now thought to be a supernova remnant. The bright red glow at upper left is the Rosette Nebula. Red Betelgeuse was at its minimum then, at about the same brightness as Bellatrix to the right — Betelgeuse is usually about as bright as blue-white Rigel at lower right. However, Betelguese began to re-brighten in the nights after this.

This is a stack of 8 x 2-minute exposures at ISO 800 with no filter and 6 x 3-minute exposures at ISO 1250 with a NISI Natural Night light pollution filter, all with the Sigma 50mm lens at f/3.2 and red-sensitive Canon EOS Ra camera on the iOptron SkyGuider Pro tracker. An additional exposure without the NISI but through a Kenko Softon A diffusion filter adds the star glows. Taken from home in Alberta on February 24, 2020.
