I’m having so much fun watching what’s happening on the Suns surface and seeing the different sunspots coming and going as the Sun rotates on its axis…but there’s much more going on that I can’t see. That’s where a dedicated solar telescope comes in, like a Lunt or Coronado solar telescope. Soon I’ll be going down that road but at the moment I’m just enjoying just looking at the sun most days through this simple set-up I have.
You must always have a SOLAR FILTER on your equipment at all times when viewing the solar surface of the Sun!
Visible light is the wavelength of light that our human eye sees our world with, the Sun emits many wavelengths of light from the electromagnetic spectrum and if you have the right type of telescope you can see all the wonders and activity on its surface. Please go to NASA’s Solar Dynamics Observatory web page where it will show you how this incredible solar observatory views our amazing star:

~ The Sun 2nd March ~
Active sunspots AR1990 & AR1991 are still the centre of attention on the surface of the Sun today. (East and West are reversed in my image) This time instead of my camera and lens set up, I used my telescope and captured some images with a solar filter attached.
One single image taken with a Canon 7D and Meade 8in Schmidt-Cassegrain telescope at prime focus, exposure was 1/500th second and ISO 640.
~ Sunspot Group AR2002 on the 12th March 2014 ~
New sunspot group AR2002 is looking really lovely on the surface of the Sun and it’s starting to develop into a very large area covering nearly 100,000 kilometres. There’s also another large sunspot on the limb coming into view…maybe some more action is about to start :-)
Image taken with a Canon 7D camera and 100-400mm lens @400 with a 2x converter with a solar filter attached to lens, ISO 400, exposure 1/1000th second, one single shot.
~ The Sun 16th March ~
Sunspot Group AR2002 and new group AR 2005 on the surface of the Sun this afternoon.
Image taken with a Canon 7D and 100-400mm lens @ 400mm with a 2x converter, exposure was 1000th second, ISO 200 and one single image.
While trying to take some images with our clubs new Lund LS80 solar telescope, I saw this huge prominence that ejected out from the limb of the Sun…it was fascinating to watch as it waved about near the limb, then it broke away and faded, this is the first time I’ve ever seen anything like this through a telescope…and it was Amazing!
~ A Sprinkling of Sunspots on the 23rd March 2014 ~
Visually, there are many sunspots sprinkled across the face of the Sun today, it looked very pretty :-)
