Betelgeuse Close-Up (HNT150 EOS Ra).jpg

Add to Cart Add to Lightbox Download
Here is Betelgeuse in a telescopic close-up revealing the red supergiant star set in a rich field of fainter stars in Orion. At this time, on January 22, 2020, Betelgeuse had faded over the previous few weeks to magnitude 1.5 from its usual of 0.5. The field of view here is 5° by 3°.

This is a stack of 8 x 4-minute exposures with the Canon EOS Ra at ISO 400 and the SharpStar HNT150 Newtonian Astrograph at f/2.8. Thus the diffraction spikes from the secondary mirror support struts.
