Re: [APML] Some Widefield Shots

Nice shots Steve! Trailing could be due to flexures or field rotation,
perhaps the former considering you seem sure about your alignment. It seems
your fog filter is very light, you should get a stronger effect according to
my experience. Which one are you using? How do you blend your shots?
