I thought I'd have a go at doing my own version of David Malin's famous image of the colours of the stars in Crux, so this was taken and processed tonight.
Captured with the Oly E-510, 1600ASA, 15 sec (to limit star trailing), Zuiko digital 40-150 zoom at 40mm (80mm eq) and f/4, ICNR on (standard), IS off, manual focus using live view.
The image is a stack of 8 photos, stacked with blending mode "lighten", image flattened and saved for the web in PS CS3. No other processing.
I took 12 photos in 15 minutes, and had a few problems
... like the remote ceased to work after the first image, so I had to go to cable release and start the sequence again, and it looks like I must've bumped to zoom on the second or third image in the sequence
... there could be some movement in the tripod as well as I was too slack to get my big tripod from my binoculars to put the camera on... the lens was entirely dewed up at the end of the 15 minutes. It was -0.7C and 85%RH outside at the time.
I will have to do this again. Next time:
- sturdier tripod
- fixed focal length lens (Zuiko f/1.8 50mm)
- try to take images at more regular intervals
