OK, astrotracer solved. You adjust the time by using the control wheel,
just like normal. The display on the back screen has totally gone away.
Unfortunately, you cannot set astrotracer for times less than 10 seconds and
it only has resolution of 10 seconds.
Can you do a sequence of multiple shots yet?
Here's a few from Mount Hamilton last night. Most shot with my sigma
20/1.7. It is now a much more interesting lens than it was on APS.
I experimented a lot with different exposures and ISOs. Changing ISO
didn't seem to make much difference in the final image (as expected with
ISO invariance), although I won't say that there is absolutely no
difference. I'll probably fiddle a bit more with processing each photo.
I did notice to my surprise that lightroom lens correction does not
have a profile for the FA 50/1.4
There is a lot to learn about astro landscape with this camera. I will
say that it is leaps and bounds ahead of the K20, which gave me the best
results at ISO 400 and something like 30 second exposures. It was well
after 2AM when I failed to figure out astrotracer, so these are all
simple tripod shots, mostly about 15 second duration. I may polish up
the processing on these a bit more, but they should be illustrative as a
lower bound of what the camera can do.
I expect that the best results would involve learning photoshop and
compositing two frames, one of the foreground and an astrotracer of the
background.
