Subject: attempted ETMY picture taking 

The attached is the ETMY image with the single arm locked. This was the best I could do. Here is the recipe

  • Turn on SP570UZ
  • Switch to "M" mode (Manual aperture and exposure)
  • Set the aperture to be the widest (smallest F number) and the exposure to be maximum (15 second).
  • Switch to AF mode by the lens side switch
  • Use the lens dial to adjust the zoom until the OSEMs fill the central 1/3 box (i.e. 1/9 area of the field of view). If you zoom more, you can't focus the spot later.
  • Use menu button to switch to ISO1600 (You are now capable to see the beam spot)
  • Switch to MF mode by the lens side switch
  • Use the lens dial to adjust the focus to have the sharpest image of the spot. This can be achieved at the focal distance of ~1m
  • Use menu button to switch back to ISO64
  • Push the shutter (I didn't use it, but you should be able to use 2sec timer)
