On the 29th September 2015 the Sun released a huge solar flare that resulted in a massive explosion from sunspot area AR2422. I set up my Meade 80mm refractor telescope with a glass solar filter attached to the front lens of the scope and took some images of the solar surface at prime focus with a Canon 700D camera. Then I put a 2x barlow lens in the system and took my images.
There were 20 images stacked in RegiStack6 and processed in PS CS4, exposures times for the images were 1/640th second and ISO 200. RegiStax6 is very good at stacking solar, lunar and planetary images.
The H-alpha image was taken with a 80mm Lunt solar telescope using a Canon 700D camera and a 2x Barlow lens.

Information from the Spaceweather.com website on the 29th September, explaining the activity around these dark sunspots on the solar surface.
Dark sunspots like these nearly always course solar flares…so I’m always on the look out for them. What is a solar flare please go NASA’s gsfc website which explains them in detail at:

NASA’s Solar Dynamics Observatory recorded this M7.6 category explosion on the 28th September 2015, 29th September (AEST) in Australia. SDO website at: http://sdo.gsfc.nasa.gov
