From sunspots to solar eruptions: Amateur astronomer captures incredible images of the sun using basic camera equipment
Jose Manteca from Begues, near Barcelona, took the photos from a small observatory on the terrace of his house
The 54-year-old says he spends hours on the terrace gazing into space, hoping to spot scintillating solar activity
He has developed a technique to take 15 images per second using a humble DSLR camera and a solar telescope
Images include stunning close-ups of solar prominences, sunspots and even a plane crossing the face of the sun
'I like photographing solar flares and sunspots with maximum detail. Now, I want to see the interiors of the sunspots.,' he said.
Incredibly, the equipment used cost him no more than £2,900.
Mr Manteca added: 'I have an achromatic refractor (meade) and solar telescope (lunt). This equipment helped me do all these images.
'My solar equipment is very simple and basic. It costed me no more than 3,500 euros (£2,900). It has worked well for me so far.'
