The Stars of Orion 30 Panels Complete - 300 image mosaic in the making.

Ten more panels making it 30 total with 7 left to edit. Really starting to come together with Barnard's Loop beginning to show.

I had a big season transitioning to dual scopes and I’m posting this one ahead of finishing out to Betleguese. I’m on a mission to make it to Betleguese before Orion sets for the year but Weather will play a big part. I’ve got roughly five hours a night left until March. It’s going to be tight. Regardless, I am on track to finish at least 25 panels this season,
Maybe even 13 more if I get the time. It’s worth noting I got 3 before switching to the dual scopes and 22 after with the week in Marathon Texas. If it had been clear all week
for us, I’d of finished this leg.

Integration per panel:

12x3min L
12x3min R
12x3min G
12x3min B
