M17 Swan Nebula ( Omega )

Captured M17 for the first time last Friday night down at my weekender
I initially planned to capture 3 hours but clouds rolled in so only managed 1 hour of worthwhile data
Seeing conditions were average with a 20km/hr southwest wind blowing ( knocked the guiding around a bit )

13 x 5 minute dithered guided subs
10 x darks
ISO 800
Canon 600D unmodded with Baader coma corrector
8” f5 newt on an EQ6-R Mount
BYEOS
Stacked in DSS
Processed in Startools

Thanks for looking

Nice one.
I started on it a couple of nights ago but managed only about an hour...spent all my time trying to get various things working. .its an absolutely perfect night here but I have just spent three hours sorting out my new caravan (used)...a gift from a wonderful lady☺ but I had to help the driver of the transporter ...long story☺ but it is in place by the nice dam so I have a waterfront ☺ and can now erect something to house the gear...probably bring the cube up or make another.

I was surprised the huge amount of ha around the Swan..its so clear here tonight I can see the Cats Paw Nebula and the Lobster Nebula with bare eyes so I wish I was not so tired.

Great colour and whispy nebula. A good target.

Do you stretch a little more and clip the blacks to a greater degree when you have less data?

Thanks
Sounds like your going to have a great set up with your caravan and obs at your dark site

No I don’t stretch the image more when I have less data , I find you lose detail ( your trying to squeeze something out of something you don’t have )
My second and final stretch I use Develop from 78 to 82. For 3 hours I would normally use 82 to 86 depending on detail
Thanks
