Astrophotographer snaps his ‘clearest ever photo of the SUN’ – a 230 megapixel image made up from 100,000 pictures
- Photographer Andrew McCarthy took 100,000 photos at about 100 per minute
- When combined they created a dramatic 230 megapixel photograph of the star
- McCarthy has been photographing the sun and the moon for about three years
- He says this is the clearest image he has ever taken of our life giving star
A sensational blood-red image of the sun, made up from 100,000 pictures taken from Earth shows our star in intricate detail, including a building solar flare.
Astrophotographer Andrew McCarthy said the image of the sun was one of the ‘clearest’ photos he has ever taken of our host star, coming to 230 megapixels.
McCarthy has been photographing the sun and the moon for three years – but this month, he took on his ‘most unique challenge’ yet.
Using a new, ultra-sharp solar telescope, the photographer from California layered thousands of images over each other to capture the sun in breathtaking detail.

The huge, 230 megapixel image – a standard camera is about 10 megapixels – shows the round sun glowing a deep, dramatic red highlighted against a dark sky.
The combined photo is so clear that even the plasma right at the outer edge of the sun can be seen – dancing around in the atmosphere like a flame.
He had to take almost 100,000 individual photos of the sun – at a rate of about 100 photos per second to capture the amazing detail.
He said: ‘I was very pleased with the final result.’
‘I wasn’t sure if the image would turn out so well, as stitching together a large photo of the sun comes with unique challenges that I’ve never dealt with before.’

‘But I will definitely be producing more of these.’
He added: ‘To capture the sun in more detail than I’ve ever attempted, I assembled a new solar telescope that gave me 4000mm of focal length, about 10x the magnification of my previous telescope.
‘I used a technique called ‘lucky imaging’, so the best frames from a particular session are stacked together to help reduce the effects of the atmosphere.
‘These photos were captured just before noon, when the sun was high in the sky but while the atmosphere was still relatively calm.

‘By capturing close up details of the surface with this rig, timed when the atmosphere was very still, I was able to produce sharp details on its surface.
‘These objects around the edge of the Sun are known as a ‘prominence’ – a mass of plasma suspended in the solar atmosphere by the sun’s powerful magnetic field.
‘These happen quite frequently, and last a long time.’
