Hi all, this may be a stupid question to some but here it is;

Obviously observing DSOs during the new moon phase at a dark-sky site is the best option.

BUT - Is there a noticeable difference to seeing faint DSOs when observing during the hours BEFORE the waning moon has risen (due to something like residual glow)?

So unless the moon is directly between the earth and the sun, even if it hasn't risen yet, does it still affect the dark(bright)ness of the sky in comparison to the new moon?

Cheers

As soon as the moon has set get out there and get into the DSO,S..

I normally go observing between 5 days after the full moon and 2 days after the new moon .......Others differ but thats me.

The moons not that noticable after and before moonset/rise.

Cheers Kev.

As soon as the moon sets, the fun begins. There is no moon induced "twilight", thank god. In these days of clouds, light pollution, wind, smoke, moon and insects, that's 1 thing in our favour!

Good to know - I assumed this to be the case but it niggles at you when you just can't find that galaxy...

Cheers guys!
