Solar Prominences by John McDonald
Although our Sun is unremarkable in many respects, its proximity makes it the only star we can study in detail. And with the advent of affordable, narrow-band telescopes, even backyard astronomers can view and image the solar surface as never before. Victoria, British Columbia, astrophotographer John McDonald captured this image of the Sun from his home on May 19. Numerous solar prominences rim the solar disc and several are visible across the Sun’s face.
He used a Canon EOS Rebel T3i DSLR camera and 2.5× Tele Vue Optics Powermate Barlow lens attached to a 60mm Lunt Solar Systems LS60THa double-stacked solar telescope to record the five frames used to make this photo.
