Today I managed to play hide-and-seek with the intermittent cloud cover and record this giant sun spot, AR3664 which has been classified as a 'Carrington-class' sunspot.
The Carrington Event was a large solar storm that took place at the beginning of September 1859, just a few months before the solar maximum of 1860.
I used the Canon EOS R7, RF 200-800mm and RF Extender x1.4 mounted on my equatorial tracking mount to grab 75 frames which I Aligned/Stacked in Autostakkert!4, deconvolved in Wavesharp and then finished in PS CC.
1120mm, 1/1,000 sec, F16, ISO400.
I fitted the RF x2 Extender to give 1600mm but the seeing (atmospheric conditions) was poor so the images were very soft and lacking detail.
Dennis.
