Nice work. Thanks for sharing.
It looks like I have a way to go. I'm pretty good with the theory on this, it's
putting it into practice that is giving me the problem.
It is what gives me the problem too. I just don't post the gazillions of tests
that didn't work out. I'll often spend an hour just trying to figure out what
will work. At first I thought that once I learned it I'd be able to just go,
set things up and shoot, but I need to dial it in every time.
One trick that I forgot to mention is to do test shots at a crazy high ISO to
get visible results in a few seconds rather than a few minutes.
If you have a 50/1.4 laying about, you may want to try just getting some
practice using it. Maybe even using it and stitching panos in post.
I'm posting my failures for the exact reason you replied to it.
I'm wise in some of the ways of photography (not astro), and I don't
mind getting pointers from people who have had some measure of success
in the genre.
I have the DFA* 50/1.4, A50/1.2 and a few K50/1.4s, and I suspect if I
dig around a bit I could come up with an A50/1.4. I know I had one at
one time.
At some point I will get around to figuring out which of them is best
for this, but first I want to be able to get good and repeatable results
from one lens per focal length that I have multiple options on so I know
I'm not muddying the waters with poor technique.
I had the A50/1.2 out the other night rather than the DFA*50/1.4 and
while it looks pretty promising, I got nothing worthwhile from it. At
least the star trails weren't showing signs of coma.
I need to drive about an hour to get away from the light pollution of
the city, but there is always some present from farm yards, so it's at
least a 5 hour jaunt for me to do anything. I'm about 4 hours from a
dark sky reserve, my plan is to get halfway competent and then do an all
nighter out there.
Thanks again.
