Wot no image!

[melvin]

Hi I tried to image the transit of Mercury yesterday but could not. I went into the 'frame and focus' tab and got the best focus I could checked the ISO (100) set the camera to 'manual' checked the camera settings on the screen in Byeos, all seemed ok so I moved over to the 'image' tab and took a shot. All I got was a white picture!!! I must have something set wrong but what, it looked fine in the first screen but nothing in the second, any advice?

The capture parameters on the Imaging tab are separate from the settings on the Frame and Focus tab.

 

The ISO and shutter speed are used to directly affect the brightness of the LiveView screen, but they do not change the exposure duration of LiveView frames which are taken and downloaded as quickly as possible. Those same parameters will generally not work to provide a properly exposed image on the Imaging screen.

 

Your image was white because it was overexposed. It was overexposed because you did not set the ISO and exposure duration on the Imaging screen. I think that the default exposure on the Imaging screen is 1 second.

 

In hindsight you should have tried imaging the sun ahead of time to "get the kinks worked out" before trying to image the once every 10 years event.

As Rick said, you are overexposed.  You need to adjust the parameters in the capture session for image capture.

Thanks for your replies, yes I should have sorted things out beforehand. I'll keep trying until I get it right and look at the things you mentioned. Once again thanks.
