Sunspot AR13007 in White Light + H-alpha 13/05/22
On the morning of Friday 13th May my friend Stuart tipped me off that there was a huge looping prominence visible on the Sun. It was cloudy at the time but I could see a few gaps possibly heading my way so I set up the solar telescope just in case. What followed was a hugely frustrating imaging session, with strong gusts of wind and lots of cloud scudding past the Sun every time I started to capture video. My laptop screen also hadn't been fixed yet so it was incredibly difficult to get focus and exposure right. By the time I got a clear look at the Sun the large prominence in question had lifted off and vanished! However, I manage to get some ok shots out of the imaging session. My white light stuff ended up being horrendous so this collage is pretty grim! It's always fun to see the two lights side by side, so I'm sharing it anyway.
White Light:
William Optics 70mm refractor fitted with a Thousand Oaks solar filter. Camera was an ASI120MC fitted with a Baader Continuum Filter, and I shot through a Celestron 3x Barlow.
H-alpha:
Coronado PST and ASI120MC fitted with a 2 x Barlow. I shot either 500 or 1000 frame videos with SharpCap and stacked the best 50% of the frames using Autostakkert! 3. Processing was done in Lightroom, Photoshop CS2 and Fast Stone Image Viewer.
