This is the active Sun on July 9, 2023, with numerous sunspot groups across the disk, including the very large region AR3363 at lower left that had just turned into view. At top is the pair of spots comprising AR3361, and at lower right another pair AR3366. Bright faculae are visible on the darker limbs of the Sun as well as the general fine granulation across the surface. North is approximately up here. This is a single image, selected from nearly 350 taken within the space of a few seconds using the Canon R5 in high-speed continuous burst mode at about 20 fps, with purely electronic shutter and with the camera in crop-frame mode to reduce the frame size and crop into the solar disk. This was through the Astro-Physics 130mm refractor with a 2X Barlow lens for f/12 and 1600mm focal length, and for 1/250 second at ISO 100. The scope had a full aperture Kendrick/Baader Mylar filter on it. The yellow coloration was added in processing. Taken as part of practising and testing for the upcoming solar eclipses.
