hello,
Plenty of fantastic Helix's around the place, here is my attempt with 2 hours 35min data, mostly 7min subs and some 5 min subs at iso 800. unfortunately a some steep gradients to deal with.
have managed to reveal part of the brighter shell but could not get a whiff of the other side. Maybe I need longer subs
or darker skies, or some filters.
I plan on getting 6-8 hours weather permitting.
