David, Jasmine, Calvin and I enjoyed Curt Nason’s first installment of an astronomy course up at Rockwood park Tuesday evening (http://rockwoodpark.ca/events/welcome-to-the-night-sky), and afterward we enjoyed some nice views of Jupiter and Saturn.
I decided to try a few pictures tonight when Saturn was higher in the sky, and here is the best of the lot:
This took a bit of experimentation, but what I did was as follows, using my Canon 5D MkIII, 500mm F4 lens + 1.4x teleconverter:
– Mirror was locked up, 2s delayed timer (that way pressing the shutter activates the lock-up, and then the 2s timer actually takes the picture — I don’t have to touch the camera at all)
– Autofocus off (pre-focused), IS on (lot’s of debate on the net around this, but since the exposure was relatively short I thought it would help more than hurt)
– I had long exposure noise reduction enabled, but the best shots were all short exposures so it would not have kicked in
– ISO 3200, 1/1000 second, f/7.1
In the end, though, that’s a pretty boring picture.
So, I spiced it up with a noisy “starfield”:
In Lightroom I did a bit of post-processing; bumped the clarity and smoothed the luminance. I like the effect and, since this won’t go into any scientific journal or to APOD, I figure artistic license is excuse enough 🙂
