The Sun and Sunspot AR2665

I read at Spaceweather.com over the week-end that the latest sunspot AR2665 was HUGE, and the biggest sunspot of 2017 so, not having photographed the Sun for sometime I thought it would be interesting to make an image of this Sunspot on the Sun.  I dug out my solar filter then Monday morning set up my camera in the backyard and waited for the morning sun to climb above the mountain tops.   I cropped this image in 25% so we can see the spot a bit better.

Sun July 10, 2017 with Sunspot AR2665

“Sunspot AR2665 has grown into a behemoth almost as wide as the planet Jupiter: Stretching more than 125,000 km from end to end and containing dozens of dark cores, the active region is an now easy target for backyard solar telescopes. Sunspot AR2665 has a ‘beta-gamma’ magnetic field that harbors energy for M-class solar flares.. “~http://spaceweather.com/

I’ll add you can see it with a Telephoto lens, and Solar filter.  Caveat: Don’t ever attempt to photograph the sun without a Solar Filter. You can permanently damage your eyes, and your camera’s sensor.

M-Class Solar Flares are Medium sized flares. They can cause brief radio blackouts that affect Earth’s polar regions.

I use an Orion 4.10″ ID Full Aperture Solar Filter. It fits snugly over my lens allowing me to look directly at the sun and photograph it by blocking  99.999% of incoming sunlight for safe observation and astrophotography.  I’ve had this filter for several years and it’s worked perfectly, and is easy to use.  It fits my 300mm f/4 perfectly. It slides over my 200-500mm’s 82mm front end element, but not so far that I’m able to secure it with the screws so, to make sure it wouldn’t fall off I taped it to my lens barrel.  Gaffers tape or Painters tape works.

I linked to the filter so you can check it out if you’re interested. I am not affiliated with Orion and do not receive any compensation or products for using their products or mentioning them.

Still practicing for the upcoming Annular Solar Eclipse.

I’m working on getting the exposure right using Live View, and reading lots and lots of articles written by other photographers about how to go about photographing it.

This is a bit blurry you’ll notice. I think this is due to all the atmosphere between me and the sun;wind, dust, clouds, etc. This morning we have clouds in the sky.

Here’s an article I liked that has  handy settings charts for a good starting base. Here’s my friend Steven’s advice on Solar Filters. Don’t try to watch or photograph this event without proper protection for your eyes and camera! I use this Solar Filter.

I’ll be driving with friends 4-5hours away from home to view this event. Will you be traveling to view the Annular Solar Eclipse?
