Sunspot AR2644

MARK FORBES, STOCKPORT, 2 APRIL 2017

Mark says: “I heard news of developing sunspots moving across the Sun’s disc. Working full time I rarely get the opportunity to image the Sun during the week, but I got lucky with cloud gaps around lunchtime! I was satisfied with the level of detail, although I learnt I should really capture some flats to help with removing dust and shadows.”

Equipment: Altair Astro Hypercam IMX174 mono camera, Altair Astro Starwave 102 ED refractor, Sky-Watcher AZ-EQ6 GT mount, Daystar Quark chromosphere filter.
