hi chucky,
nice one, sounds like you are slowly getting it all together.
it is a bit of a balancing act trying to find the right balance for exposure time vs sky glow. I can really only go to about 70 seconds, maybe slightly longer depending on direction.
you need to experiment to see what works for you. of course if you are taking photos when the moon is out it complicates it again (best to avoid). one way of extending your exposure time is by purchasing a light pollution filter.
also are you stacking your photos and using any editing software?
cheers
Russ
