Sorry mate, i haven't checked this for a while - im fairly sure it is correct. - i don't have the reference in front of me and yes, 0.1 but now you've confused me, but I did have a crack around when i posted my last one, i got 18 seconds for 45 degrees altitude from your profile location looking due east or west.
the best spot is near east or the west and under 45 degrees alt. you are closer to the equator which makes it not as good for you (if you were at the pole it would pretty much make it equatorial!). But saying that my photos were 20 seconds, and its the outer part of the frame that gets the field rotation first. you can stack and crop out the perimeter.
keen to see how you go
