Are You Ready?

I’m sure many are practicing solar imaging these days. This is today’s sunspots. Huge spots make imaging fun.

Thanks for purchasing KENKO or IDAS solar filters. We are quite busy to ship all out every day. Thank for making us very busy!

I noticed there are many who never shoot the sun. So let me have some tips to make imaging more fun, easier and safer.

1. Always double check if the solar filter is securely set in front of optics first. This is a kind of must-procedure to makes solar imaging as well as viewing safe. The sun has huge energy. So don’t hesitate spending the time to check back all the time.

2. Pointing telescopes or telephoto lenses to the sun : Use the shadow. When lens and camera’s shadow is lined up, it is pointing to the sun. This is to minimize or totally avoid looking at the sun during pointing work. Basically I don’t recommend looking at the sun without solar glasses etc.

3. Focusing : Use camera’s liveview function. Optical viewfinder is hard to see fine details. Use black spots to focus and be patient since spots are dancing around because of the air.  BTW, for KENKO filter users, I don’t recommend looking at the sun through optical viewfinder long time.

4. Faster shutter speed is always better to minimize affecting image quality by the air turbulence. Take some test shots and see histogram. You will see two separate curves. The sun’s data is only brighter one. As long as it is not saturated or too under-exposure, that’s fine.

5. And finally enjoy these spectacular events!!

If I get aware some other tips, I will write up here. Also if someone have any questions, please feel free to contact me any time.

  1. Great tips, Ted. Most of my solar imaging is done via eyepiece projection from a Hyperion 8-24mm zoom to the Canon 60D.

    Allow me to add two more tips to your excellent list.

    I focus on the rim usually at 5X live view, infrequently at 10X. Dimming a bright image by shortening the shutter speed also helps determine where best focus is via the Canon’s LCD screen.

    Wider FOV, i. e., shorter FL, is the easiest way to shoot the sun.

    Often, full disk images are really good, especially if there is something like sunspot AR-1476 present, as is there now. It’s relatively large.
