G'day Carl
I am just a beginner, so I can only offer praise/support rather than any quality advice.
I think it is a great start and you should be happy there considering the issues faced (i.e. moon and in Brisbane, surely some significant LP issues).
I have just started on DSO's this week and have found it to be a steep learning curve from a move from planetary and solar imaging. I am starting off with Nebula and when I get a bit more proficinent I will try my hand at galaxies.
Keep em coming and I will watch out for your new and improved images.
Regards
Gav
