My first attempt at Alberio this year , using synscan goto mount with a small scope , cannon 1100d .
It is a stack of 5 15 second exposures .

Sun Spots (June 4th Club Night)

Warning.
Never look at the Sun through any Lens based device.  Telescope, Camera, Binoculars, WHY !
Looking at or near the Sun will cause instant and irreversible damage to your eye. Eye damage is often painless, so there is no warning to the observer that damage has occurred until it is too late.  Children should always have adult supervision while observing the sun.  If the above is the case, how do we photograph sun spots, prominences, partial / total solar eclipses ??? , by using special telescopes and filters that remove 99.999% of the harmful light thus allowing visual observation and images to be taken.
The above said, here are two images taken using an 8" SCT telescope with a Thousand Oaks Solar Filter and a normal DSLR. You can clearly see the sun spots. The images shown are stacks of 20 individual DSLR images, stacked to give the composite. The upper images were taken at 1/400 sec @ ISO 800, the lower image are 1/125 sec @ ISO 1000
